Croatia 2023: Climbing our first Big Wall – Anića Kuk

The cursed day

6th July has become, through pure, uncanny coincidence, a day on which something significant happens to me. I may write about this separately (think car crashes, ultramarathons and multi-mountain hikes) so I’ll skip straight to 2023, which was no exception: Ryan and I decided to climb our first big wall*, the 350m vertical north face of Anića Kuk in Paklenica National Park, Croatia.

*there’s no hard and fast definition of what constitutes a “big wall” but the infallible source of all verified knowledge (Wikipedia) describes big wall climbing as a form of rock climbing that takes place on long multi-pitch routes that normally require a full day, if not several days, to ascend. While we didn’t plan to spend the night on the wall, we chose a route called “D. Brahm” (5c), a  300+m, 13-pitch classic that would probably take at least most of the day, so as far as I’m concerned it qualifies. This route was named in honour of Dragutin Brahm, a climber who died while attempting the first ascent of Anića Kuk – on this route – in 1938.

This year, 6 July taught us the following climbing-related lessons:

  1. Find the route
  2. Don’t throw gear off cliffs
  3. Mind out for dead things
  4. Treat loose rock like glass
  5. Take enough water

We learnt these in the following way.

Thursday 6 July

After Ryan’s little wobble whilst climbing in the canyon on Tuesday, and having researched D. Brahm as thoroughly as possible, which was less than I’d have liked given the limited information available online, we felt the weight of anticipation prior to our first ever big wall climb. We half-heartedly shovelled down some cereal (leftover rice slop for Ryan) and left the apartment at 7:30am, carrying rucksacks containing questionably light climbing racks. We’d packed minimally to keep luggage costs down and we desperately hoped that we had enough gear to make it up the route, which was technically a sport (bolted) climb but with some run-out pitches that would require additional trad placements to protect against potentially huge (40m+) falls.

To save time and energy we drove a short way up the road to the entrance to Paklenica, showed our three-day passes at the gate and followed the winding track up the gorge towards the mountains, which loomed ahead looking vast, rocky and slightly menacing. We parked by a thick, leafy forest at the mouth of the canyon, whose vertical limestone walls rose high either side of a gravel path as if designed to make the visitor feel quite inconsequential, and headed up the great cleft towards Anića Kuk.

After 15 hot minutes its enormous, pale north face appeared ominously around a corner, rising high into the clear blue sky like the hunched back of a great, rocky monster. We identified the vague, wandering line of D. Brahm using an information board showing the main routes and reflected that its northerly aspect meant we’d spend most of the day shaded from the hot sun. Satisfied with our reconnaissance, we crossed the valley via a steep, narrow path through lush woodland, following signs to Anića Kuk and even our chosen route:

We emerged from the trees and stopped at the base of the wall, which suddenly gained a new dimension. Rather than a flat, sheer face, it now looked like an impossibly high, slightly-less-than-vertical series of slabs, cracks and shrubby ledges jumbled in a complex arrangement that made it likely we’d only be able to see small sections of the route at once. This would complicate route finding, which we suspected would be difficult anyway given the size of the wall and the fact we were relying on website screenshots and a photo I’d sneaked from a guidebook in a shop.

Nevertheless, we were excited to have arrived. We identified what we thought was the start of the route, harnessed up, tested the radios and talked through our plan.  I was to lead the first pitch as that would mean that I’d also lead the crux (hardest move) at pitch seven, but – as I’ll explain later – this didn’t go to plan.

Pitch 1 (4b made harder): Route finding

I set off at 9am by a large memorial plaque for D. Brahm – which turned out to be ill-placed – and followed an easy crack up a slab. My confidence was misguided: after about ten metres the route became uncertain. Knowing that it went left at some point, I made some delicate, balancey moves across the exposed face of the wall to an insecure stance, where I placed a trad nut into a crack and rested on it while I worked out where to go.

After a vain, time-consuming attempt at continuing upwards over a holdless bulge onto more featureless slab, I conceded that I’d already lost the route and returned – a little sketchily – to the crack I’d come up. Ryan suggested going right, on which advice I soon rediscovered the route (my heart leapt when I spotted a bolt) and realised that I’d gone for a more difficult, direct start, rather than setting off up a chimney about 10m to the right of the plaque. This was confirmed when Ryan spotted, quite unhelpfully by this point, a triangular tag on the rock indicating the “true” start of the climb.

Happy to be back on track but slightly apprehensive at how difficult the rest of the route may be to stick to, and consequently how long it might take, I continued along a diagonal crack up an easy gradient to a grassy ledge and the first belay.

P2 (3b): Blocky

Ryan followed me up, unimpressed at having to make the awkward sideways moves to retrieve the wayward nut, and proceeded to lead the long, blocky second pitch – which had just one slightly awkward move up a corner – without difficulty.

P3 (4b): Shrubby

I seconded pitch 2, passed Ryan and led pitch 3, which went directly up another easy corner, where shrubs clung to the wall in little pockets and trees perched on small ledges. Ryan followed, met me at the belay and continued past, following a red painted arrow, which was very helpful here as the route veered suddenly off to the right.

P4-5ish (4a): Sideways

He traversed along a diagonal fault, then disappeared around another corner. I belayed patiently, wondering what was taking him so long, and struggled to pay out rope as it dragged sideways through the bolts – which were few and far between – and trad gear.

After a good while I heard him call “safe” and prepared to follow while he pulled in the slack, which – given the distance he’d climbed – was a relatively small portion of our 60m twin ropes. I completed the long, straightforward but exposed traverse across the wall (which would not have been a good place to fall as it was very “sideways”) and discovered the cause of the delay and the rope drag: Ryan had strung together pitch 4 and most of pitch 5 by bypassing the fixed anchor at the end of pitch 4. In fairness I didn’t see it either, so can’t blame him.

I found him at a hanging belay beneath an intimidatingly vertical, slabby face, attached to two bolts with nothing under his feet but an overwhelming amount of air, and congratulated him on his excellent management of both ropes, which – in the absence of a surface to place them on – were folded neatly across his cowstail (the short length of rope attaching him to the bolts). This turned out to be the belay for another route, “Black Magic Woman”.

Although the climbing was easy, we were now over 100m from the ground and the exposure was exhilarating. Luckily neither of us were fazed at all by the sheer drop below – we had expected to be fine, but having never climbed a big wall before, we accepted that we wouldn’t really know until we were there. Enormous beech trees filled the belly of the canyon like a mossy floor, interspersed by gargantuan, house-sized boulders that looked like pebbles, and a small forest clearing revealed a helicopter landing pad that looked fit for a bumblebee. It was sensational.

P5ish-6 (5a): Dubious rock

I joined Ryan at the uncomfortable hanging belay and we deliberated over which way the route went. We thought that he’d done pitches 4 and 5 in one but weren’t 100% sure. We couldn’t see anything to the right, so on spotting a line of bolts set close together up the vertical slab to our left (perhaps that should have been warning enough, as all the previous bolts had been many metres apart), I set off upwards to see if the moves were easier than they looked. I discovered, three bolts up, that they were not, at which point Ryan conveniently spotted a bolt set way over to the right, almost level with him. Relieved but still in a precarious position, I downclimbed delicately, unclipping quickdraws as I went, and later realised that I’d made several balancey moves up a 6b+ pitch of Black Magic Woman.

I squeezed awkwardly past Ryan and made a long, airy traverse to the right. I clipped into the bolt he’d spotted, to both our relief (he’d kindly pointed out the great fall I’d have taken before the bolt, of which I was extremely aware), then pulled up a loose-looking, blocky section and discovered the belay bolts at the end of pitch 5. Ignoring them, I moved up and left across a pale, disconcertingly fresh looking slab, placing a couple of nuts and hoping that any newly exposed rock would hold in the event of a slip. I reached the anchor after a tricky move up a steep diagonal crack, then radioed Ryan with instructions to watch out for the loose-looking flakes. The radios were proving a godsend on these long, wandering pitches, where climber and belayer were often out of sight. He followed and joined me on my narrow belay ledge.

P7 (5c+): Ordeal, loss of an ally

We looked upwards into a distinctive chimney, which was 2-3ft wide and topped by a large chockstone (a loose block held between two vertical walls). Although the shortest pitch of the route, we’d read that this was the awkward crux – the hardest section. We’d planned the route so I would lead it as Ryan’s confidence had taken a knock a couple of days before, climbing in the Klanci valley way below where we were perched, but as we’d strung two pitches together and were alternating leads, it now made sense – from a time and faff perspective – for Ryan to lead. I offered but he mulled it over and decided to try it, to my disappointment – a mild disappointment that was tinged with quiet relief.

The chimney didn’t look too difficult from below, although almost immediately after setting off Ryan reported that it lacked holds and that its two opposing walls – against which he jammed his body, relying on the outward pressure of his back, feet and hands – were polished and slippery. In an attempt to gain friction he dipped his hands into the single chalk bag we’d brought in a desperate, and with hindsight misguided, attempt to reduce the weight of our luggage on the plane. Looking for other ways to make the pitch easier, he realised that his rucksack was a hindrance as it pressed against the chimney wall. He rested on a cam he’d placed in a crack and went to unclip the waist strap so I could take the bag.

Unfortunately Ryan unclipped the wrong strap. I watched helplessly as our single chalk bag, which had belonged to me and seen me up hundreds of climbs, tumbled in slow motion down into the airy void, landing neatly on a grassy ledge way below with a dramatic puff of chalk dust. There was a brief, stunned silence as we processed the loss, then all we could do was laugh. The polished crux – and the rest of the route – would have to be tackled without additional friction.

Thankfully this section had three close-together bolts for protection and the cam was good, so a fall would have been minor. However, I’ve never belayed an uglier pitch. Ryan scrabbled, clambered and humped his way up the smooth chimney, his movements resembling those of a large, unwieldy bear. He made it to the top bolt, which was just below the chockstone, had a quick rest, then threw (and I don’t use that word lightly) a leg across the gap to a miniscule hold on the right hand wall.

I watched dubiously from directly below him as he did his own mediocre version of the splits, concerned for the welfare of his inflexible tendons; was deeply alarmed when his left leg followed his right so his body was almost horizontal; then I marvelled as his desperate attempt to surmount the chockstone – with something like a semi-controlled, semi-frantic bear-hug-come-bellyflop – appeared to work. I was still processing my emotions (a heady clash of anxiety and amusement) when he suddenly disappeared over the top of the chockstone, still horizontal, in a strange, smooth movement, as if dragged into the belly of the mountain by a great, rock-dwelling monster. His feet vanished, and I knew that he’d completed the crux.

Once he’d set up the belay, a triumphant Ryan – who was highly satisfied with the theatre he’d just performed – cut short my rendition of James Blunt’s “Goodbye my Chalk Bag” and I started up the chimney. I made no lighter work of it that he had, but thankfully there was nobody below to bear witness. I jammed my body between the walls, cursing the two lumpy rucksacks on my back, agreed that it was very polished and devoid of good holds (the okay-looking blocks at the back of the chimney were useless), and made quite a scene of salmon-flopping my way onto the chockstone.

Lunch with a view

I scrambled up to Ryan, who was tucked into a corner of a rocky, grassy ledge looking harrowed but pleased with himself, and we contemplated rappelling down to retrieve the much-lamented chalk bag. This would have been time-consuming so we decided to have lunch instead, then press on. Fake sausage and fake cheese in tiny slices of strange bread never tasted so good.

As we ate, we took in the exposure and the view across the canyon, which seemed both miniature and gargantuan. Tiny people trailed along the barely visible path way below, beneath hulking limestone cliffs across the valley, and the moss-like forest filled the canyon belly like a wide, green river curving around the base of the mountains. Up the valley distant green and grey peaks sprawled across the horizon, and on either side of our ledge, vertical walls plunged into nothingness above and below.

P8 (3b): Grassy scramble feat. anty bat & loose blocks

Once lunch was over I set off up pitch 8. I climbed a short wall above Ryan’s head and on mantling over the square lip, I saw that I’d been lucky – I’d blindly placed my palm onto a flat ledge a couple of inches away from a small, dried bat, which was peppered with ants. I alerted Ryan to the presence of the bat, topped the wall and continued up a grassy gully. This section was little more than a long walk up a relatively gentle slope, which was strewn with boulders and shrubs, but – although easy – it required some caution, as it was littered with loose rock.

A complete lack of bolts led me to wonder if I’d lost the route, but I decided it more likely that the rock on this pitch was simply too unstable to be trusted. At one point I placed a hand on a block the size of a small football, set on a sloping, outward-facing ledge at chest-height, and froze as it moved under my touch. I realised that I was now supporting both its weight and the weight of another, cricket ball-sized block above it, so – very cautiously – took the smaller block, placed it carefully on a flattish bit of the ledge (which wasn’t quite as flat as I’d have liked), and used both hands to move the larger block to a more stable position. While holding these rocks I was acutely aware of the gravity of this situation – if I’d had a clear view below, and wasn’t 200-odd metres from the ground, I might have cleaned them from the route, but all I could see behind was the narrow, V-shaped channel I’d come up. Ryan was out of view at the base of the bat wall and I had no idea who might be below us, so I handled them as if they were made of glass.

Disaster averted, I continued up the gully and was quite relieved to find two anchor bolts, connected by a short rope sling, up a steep block next to a tree. One of the bolts was too small to clip so I clipped the other, the sling and the trunk to make a “tree piece anchor” (a name I remain proud of), then belayed Ryan up while fending off some kind of flying, buzzing insect.

P9 (3b) – P10 (4a): More scrambling

Ryan followed without difficulty, then passed me and led pitch 9. This was another easy scramble, so – conscious of time and perhaps not satisfied with what felt like a glorified hike – he continued on to lead pitch 10, which went up a steeper, slabby corner at the top of the gully. I was glad when he radioed to tell me he’d reached the belay, as it meant I could stop grappling with rope drag.

P11 (4a) – P12 (4b): Mile-high traverse

I joined Ryan at the belay and continued up pitch 11, which involved some straightforward moves up another corner to a platform with two sets of bolts. Feeling a bit short-changed, I decided to carry on up pitch 12.

I moved off the platform onto a steep slab with a single distinctive feature: a straight, diagonal crack stretching way out to the right, with a line of bolts showing the route. This afforded an excellent, very airy traverse, and I was exhilarated by the exposure as I padded sideways with nothing beneath me but a dizzying drop where the slab plunged towards rocks and trees that may as well have been a mile below.

I climbed very carefully, fully aware that a fall would mean a big swing from the horizontal, still fairly spaced-out bolts. Having strung the two pitches together I really struggled to pull the rope through, as the change of direction caused a huge amount of drag. Despite this difficulty I had no regrets – for me, this pitch was probably the most fun.

I reached the end of the crack and the gradient eased as I pulled above the slab. I suddenly felt the warm sun on my face and realised that having spent the day in the shade of the wall, we must be nearing the top. Scant bolts ran parallel to a blocky wall on my left, and I followed them upwards, heaving on the rope, past a tall, leafy tree until I came to the anchor set into the wall.

I set up the belay and absorbed the view. The lumpish mountains across the canyon didn’t seem quite so vast from this height, tapering down to a just-visible sea via the smooth, pale grey curve of a westerly ridge. The water shone bright in the late afternoon sun, which bathed the peaks up the valley in a warm light that cast angular shadows and accentuated their intricate contours.

Ryan receives my wrath

Just as I felt the end was in sight, I went to take a sip of water from my hydration bladder. I was thirsty as I’d rationed my three litres carefully throughout the day. I was rewarded by a few unsatisfying drops, then the disagreeable, rubbery resistance of an empty pouch as I vainly sucked air from the tube. I thought of Ryan’s thirsty gulps from the mouthpiece, which dangled – perhaps too accessibly – over my shoulder, after previous pitches, and vividly recalled telling him to make sure he had enough water before we left the apartment (ie. more than the 500ml that he did take). Inwardly seething, I prepared to give him a piece of my mind when he joined me at the belay.

That I did, my mood not improved by hauling at the dragging rope, after he skipped up the two pitches and had the cheek to conclude that it was pleasantly exposed and thoroughly enjoyable. My fury at such an amateur mistake was dampened slightly by his enthusiasm to finish the route, and further by the breathtaking scenery as I pointed out the dazzling sea. I decided not to drop him as he set off up the near-vertical start of the final pitch.

P13 (4b+): One tough move

He climbed up the slab, following a line of spaced-out bolts. Several metres up he made a difficult, no-hands move on small footholds to reach for a lofty crimp. I watched, impressed, and silently forgave him – temporarily – for his silly oversight. He pulled up, topped the slab and disappeared for a while as he searched for the route.

After what felt like a long, thirsty wait, he radioed to tell me he was safe and setting up the final belay. After a few minutes I followed him up, doubly impressed by the balancey move up the slab on discovering how small and far apart the holds were (although as it was only graded 4b+, I put its difficulty down to mental weariness after sustained concentration throughout 12 exposed pitches). I pulled over the top and arrived at a large mound of jumbled boulders that proffered no indication of how to surmount them.

I followed Ryan’s instructions to go left and weaved my way up the unprotected final scramble. My water woes were completely forgotten when a spectacular rock arch appeared above me, then Ryan came into view, belaying from a large boulder underneath it. I clambered up the last few metres and walked over to him, a little dazed. We’d topped the face of Anića Kuk at nearly 6pm, nine hours after setting off up the first pitch. The first thing I said was “we didn’t die!”.

Victory

We were both taken aback by the sudden flood of emotion. Having never climbed anything so committing, technical and exposed before, our previous multipitch experience being limited to the classic VDiff ridges and scrambles of Scotland, North Wales and the Lake District, we were overwhelmed by relief, slight disbelief and a completely shameless feeling of triumph. The realisation that we were capable of a big wall was empowering: it was as if we’d broken down a barrier to a whole new world of climbing. We hugged, congratulated each other on our competence and continuing state of aliveness, and drank in the panorama of sun-drenched mountains and sea.

After investigating the magnificent natural rock arch, through which was a wonderful view of the long, opulent Adriatic inlet between Starigrad and the flatter part of Zadar county, we collected ourselves and crammed our chaotic array of climbing gear into our rucksacks. We scrambled up a rough, rocky bank next to the arch onto a boulderfield plateau and hopped around on large rocks looking for the red painted circles that denoted the “climber’s way” down the south side of the mountain, which was not shown on my map of Paklenica. The view was now panoramic: layered, hazy ridges of triangular peaks swept down to the glistening sea on one side, and on the other the high, grey-green mountains of the southern Velebit range sprawled majestically across the horizon, looking just as staunch as they had done earlier but – now that we’d conquered one of them – less menacing.

A harrowing descent

Regrettably my enchantment was jaded slightly by thirst, and we were both keen to leave Anića Kuk behind us for a drink of water. We found the painted waymarkers and clambered down the large, awkward rocks until we came to a thick, via ferrata style wire cable dropping several metres down a nearly sheer wall of boulders. I knew I was dehydrated because I felt quite weak as I leaned back on the cable, feet on the wall, and slid down slowly to avoid skinning my unprotected palms.

The going was tedious down the steep, irregular terrain, and unfortunately there were several more via ferrata cables requiring utmost care and concentration. My irritability at Ryan’s silliness had returned in full force and we descended in stoic silence, both focusing hard on every foot and hand placement. Thankfully the red markers were numerous and easy to follow once off the plateau, although the Klanci valley below didn’t seem to get closer for a very long time, and the terrain did not ease, remaining loose, blocky and steep the entire way. I couldn’t remember the last time (if there was one) I felt so parched – I was certain my body would shrivel up like a raisin before we got back to the car.

We plodded down the mountain in this way for what felt like an age. Eventually, after descending an enormous, very steep, loose bank, we reached the cobbled path in the valley. We contemplated walking up it – about 15 minutes – to the drinkable spring water pipe we’d found on the way to Manita Peć cave a couple of days before, but decided to save ourselves time (in case I shrivelled up) and drink from the hose by the National Park entrance hut, where we’d previously seen a motorhome fill up 5L bottles.

Salvation

We headed down the valley and were back at the car in 10 minutes. Salvation was in sight, nearly two hours after beginning the descent. We drove away from the canyon down the narrow, winding road and stopped at the little entrance car park. Agonisingly someone else was using the hose, which was fed by the Paklenica River and evidently filtered through pipes in a small concrete structure a little further upstream. I dashed for it the second it was free. I downed two 500ml bottles in seconds and it was heavenly. Never before have I tasted such pure, cold, clean-tasting water. Ryan was now truly forgiven, although the incident won’t be forgotten – I’ll certainly be reminding him to take plenty of his own water in future.

We returned to the apartment down the road and collapsed onto the bed, giddy with a wonderful feeling of accomplishment. I had one more mountain to overcome that day – washing my hair – so I jumped into the shower while Ryan cooked dinner. Despite barely eating all day, we weren’t really hungry until we tucked into a delicious bowl of rice slop with cheap sausage, tomato and whatever else he found in the fridge. We went to bed without washing up, exhausted, delighted to have ticked off our first big wall climb and slightly relieved to be back in one piece.

Croatia 2023: Plitvice Lakes National Park

Disclaimer: Strap in – this was a difficult, lengthy post to write as I wanted to do justice to the intricacy and other-worldly beauty of Plitvice. Please excuse my rambling descriptions, inclusion of utterly unpronounceable names and repetitive variations of “blue”, “green” and “clear”…

Wednesday 5 July

After researching Plitvice Lakes, we’d initially decided that 40€ each was too much to pay to visit a National Park. However, I’d seen some photos and the seed had been planted, which meant (as it always does) that I’d inevitably reverse that decision. I decided to treat us to the trip on the conditions that Ryan a) get up early, and b) drive us there without damaging the rental car.

The journey

We were on our way by 6am. The 1h40 journey was traffic-free, which was just what Ryan needed to get used to driving on the “wrong” side of the road. We joined the tunnel-ridden E71 motorway shortly after leaving still, peaceful Starigrad, nestled between the Paklenica mountains and an inlet of the Adriatic sea, and entered Lika-Senj County to the north, which was – to our mild surprise – shrouded in early morning fog.

We arrived at Plitvice at 7:30am, parked very carefully at Entrance 1 and made our way to the chalet-style ticket office. There was already a long-ish queue and I was concerned that having made the journey without booking, we’d come across some issue that would prevent our visit. My foreboding was not unwarranted as the card machine didn’t like my bank card, but luckily a different card worked and we received tickets after an anxious few minutes.

We passed through the entrance and went straight to the information boards showing seven waymarked hiking routes, which I’d already researched online. We naturally picked the longest, an 18km trail that circumnavigates nearly all the lakes and cuts out the land trains and electric boats (bar one) that shortcut around the park. Having photographed the board, we wandered over to the start of the trail and were instantly blown away by the landscape.

Lower Lakes:  Veliki Slap waterfall to Milanovac

If we’d have been in a cartoon, our jaws would have hit the floor. A vast limestone valley opened up below us, pale rock walls rising from large pools that were bluer than blue and so clear that we could see the bottom from our high vantage point. These pools were set at different levels, and fell into each other via multitudinous cascades that tumbled as vertical columns of pure white water so bright that they seemed to emit light. A forest of the lushest, most brilliant green covered every inch of land that wasn’t rock or water, almost glowing, and across the valley the highest waterfall, Veliki Slap, dropped out of the trees at eye-level and disappeared behind a vegetation-covered, natural limestone dam, which held the torrent back from a series of small, tiered, turquoise pools set low in the basin. A distant mountain ridge stretched hazily across the horizon, just visible above the forested valley side, beneath clouds of white and lilac-grey interspersed by occasional blue patches. It was as if the sky, in deference, reflected the land.

We followed the handrailed, switchback walkway down the side of the valley, feeling as though we were dropping into a real life Avatar set. It was already getting busy so we were keen to see Veliki Slap, “Big Waterfall”, before the crowds descended. The lakes grew in size and clarity as we approached from above and looked impossibly, almost unnaturally blue. We reached a rustic (but solid) boardwalk across the water between Novakovića brod lake, which was level with us, and the Korana river, which was set low in the valley and fed by an abundance of falls bursting improbably from invisible sources concealed by leafy vegetation. We wandered along this boardwalk marvelling at everything: the lakes, the falls and the incredible variety of water grasses and leafy plants on either side of us. It was impossibly beautiful.

The boardwalk snaked around a sheer limestone face to Veliki Slap, a 78-metre high column of water surrounded by tens of narrower, only slightly shorter falls. It was utterly magnificent: I wondered how there was enough water on Earth to feed this powerful, constant giant, which erupted from the clifftop treeline high above. Once we’d gazed in sufficient awe we snapped a couple of photos and returned to the boardwalk, aiming to break away from the growing number of tourists collecting at the base of the unimaginatively but accurately named Big Waterfall.

We followed the boardwalk along the western side of Kaluđerovac lake, still awestruck by the water, and crossed a low limestone barrier between tiered pools to a path along the eastern side. The shallows were gin clear, melting to translucent turquoise and almost opaque blue-green in the middle as the lakes deepened. Fish basked nonchalantly in the open water, and the perfectly flat surface reflected pale rock walls and green forest across the valley.

The path bordered Gavanovac and Milanovac lakes under a leafy canopy and we walked past several tantalising, dark caves set into pale limestone walls on either side of the valley. The number of visitors had dwindled, as we’d predicted, and after a kilometre we crossed another low dam via a boardwalk over shallows brimming with vegetation. Wide, multi-columned Slapovi Milke Trnine and Milanovači Slap waterfalls rushed out of these shallows below us, connecting great Kozjack lake to its smaller sister Milanovac about six metres below, and I was in awe at how the rock held these vast waters back from each other.

Upper Lakes: Kozjak to forest trail

We followed the edge of enormous, irregularly shaped Kozjak to a large visitor area containing dozens of picnic tables, wooden food kiosks, a gift shop, toilet block and the first boat station, where tens of people queued to cross the lake. Happy not to join this rush, we continued along the western edge for a couple of kilometres, snaking round the lake’s undulating border through the fringe of a rich beech forest. We drank in the quiet serenity of the flat water and almost overwhelming brightness of the blues and greens, feeling utterly content now that there was nobody else around, save for the occasional pair of other visitors looking to experience the place in solitude.

The path climbed a short way into the trees, affording stunning views over Kozjak, which – now that the sun had emerged – was a perfect mirror of the verdant forest on the opposite bank. I was amazed by the biodiversity of the woodland, where all kinds of low plants, shrubs and fungi covered the floor beneath a glowing canopy. We had a good view of thickly forested Štefanijin otok, the park’s sole small island, before finding another waterfall about eight metres in height and width tucked away – somehow subtly – in a leafy corner.

We climbed a set of stone steps up into the forest, then walked down a bank and found the ferry dock, where most visitors disembarked having caught the boat across Kozjak. We had a minor disagreement over which way to go – I was keen to continue on Route K but Ryan was concerned that we’d miss out on the waterfalls, so wanted to go with the throng along the low path by Burgeti lake. I conceded at first but after about a hundred metres became stressed by the influx of slow-walking people constantly stopping for photos, so – to Ryan’s initial chagrin, but eventual approval – we turned back, climbed the wooded bank above the busy path and continued on a quiet, sun-dappled trail beneath towering, impossibly green trees.

Upper Lakes: Forest trail to Okrugljak

After a short way we came to a clearing and looked down across the glassy blue water of lagoon-like Gradinsko lake to Veliki Prštavac, the second highest fall in the park, which formed a wide series of white pillars erupting from the forest above. To call it a fairytale scene wouldn’t do it justice. The path then continued for a few kilometres under a high beech canopy that covered a steep bank overlooking a multitude of smaller lakes, which formed a watery patchwork that filled the valley floor, separated by snaking, leafy rock barriers. I was looking out enthusiastically for grizzly bears, featured in the National Park’s logo, but (to my disappointment) was only successful in spotting some large bracket fungi and some pretty nine-spotted moths:

Any remaining sourness from our disagreement dissipated the minute we emerged at another clearing, where the path turned sharply left before descending to the popular trails. We gazed over the blue glass of lake Ciginovac, surrounded by rising green forests, and above it, the vast, hanging lake of Prošćansko – almost as big as Kozjak, and just as irregularly shaped – whose mirrored surface shone into the sky, the unimaginable weight of water impossibly suspended by a steadfast limestone dam. It was as if the rock stoically kept the lakes in check, permitting water to move between levels via numerous regulated falls, but had no control over the vegetation, which spread on all but its most vertical surfaces and encroached in the shallows as if showing off its leafy mastery of the landscape.* I pointed out to Ryan, blissfully aware of my capacity to irritate, that we’d never have seen Prošćansko on the popular trails. I think he forgave me.

*This later made sense, on learning about the formation of tufa barriers – no spoilers here, you’ll have to read on

We wandered down the hill through more forest, paused at a viewpoint over three of the little patchwork lakes to admire more falls bursting from various treelines, took a couple of switchback turns and emerged back onto the tourist route by the edge of Okrugljak lake, where we rejoined the steady flow of visitors.

Upper Lakes: Okrugljak to Galovac

Another curving, handrailed boardwalk granted passage across the green strip of vegetation between small, bright blue Veliko jezero and Batinovac lakes, and I was delighted to see a two-foot long brown snake zipping effortlessly through the clear shallows in a graceful S-shape between roots and reeds.

Having crossed the water, a path took us slightly away from the azure lakes into a rainforest-like area of woodland, then north along the eastern side of Galovac, where an information board taught us how the limestone dams between water levels are actually called “tufas”. They are formed by a gradual build-up of calcium carbonate deposits from moss, invertebrates, bacteria and the blue-green algae that give the water its bright blue colour. These barriers are estimated to be 6,000-7,000 years old and grow at an average rate of 13.5mm per year. It was as if the science behind the landscape was necessarily explained to convince visitors of its reality.

Water tumbled in tens of narrow pillars down the tufa at the head of Galovac, its vertical course replicated by green columns of grass and moss that hung over the side of the dam. Yellow, pink and purple wildflowers climbed the tall, grassy bank below the forest edge, and fallen trees below the water’s surface accentuated its blue clarity, the long forms of their majestic trunks fully visible as they stretched far from the bank. We skirted along the edge of the lake, passing a photogenic trio of goosanders (it was strange to see a UK-dwelling bird in this exotic place), and stopped for our customary holiday lunch of highly processed ham and cheese sandwiches on a fallen tree trunk just off the path, overlooking an irresistible little lagoon.

Veliki Prštavac waterfall and Upper Lakes: Galovac to Kozjak

We didn’t hang around for too long, noting the presence of several large ants, before continuing past the gin clear shallows at the northern end of Galovac. The path took us through a wooded area between lakes, past another high, grassy waterfall and down a steep bank onto a busy, snaking boardwalk between Galovac and Gradinsko, where completely colourless water flowed steadily beneath our feet. We ambled along at the slow pace of the single-file line, approaching the base of 28-metre high Veliki Prštavac, which we’d seen earlier from high in the forest. It had looked quite tranquil from a distance, but proximity betrayed its intensity as white water rushed urgently in a wide, multi-columned wall into the pool below, its fine spray relieving us of the hot sun. Again, vegetation was everywhere: trees grew above the falls, grasses hung low over the edge of the barrier, mosses concealed every inch of rock and rhubarb-leaved water plants (I’m a poor botanist) crammed the edges of clear pools.

We passed a small crowd taking photos of the waterfall and continued on the boardwalk, which twisted tightly between several small, clear pools lined by reeds and slim, pale-trunked trees. Numerous falls poured from forest-topped tufas thick with hanging, trickling grasses and opportunistic shrubs, bursting from every nook and cranny that would take a root, and every inch of ground was covered by what seemed like a hundred different plant species. It was fascinating, and I wished desperately (despite the in-fittingly rustic boardwalk) that I could have seen the park before the age of tourism and slipped into its cool, clear, blue-green waters.

We wandered through this surreal, intensely detailed, prehistoric oasis until the boardwalk straightened along the edge of Gradinsko. A path took us through verdant pine and beech forest to the boat station at the southern end of Kozjak, and after a short wait we boarded and sat at the front of the electric boat as it carved smoothly across a narrow section of the lake past Štefanijin otok island to the eastern bank.

Return from Kozjak

After a quick loo break at a chalet-style café, we set off north on the quiet, shady path back to the park entrance. This trail hugged the eastern edge of the lake, and on clambering onto an overhanging tree for a terribly touristy photo, I – to Ryan’s great amusement – very nearly overbalanced and fell in. I dismounted quickly, muttering something about how a rucksack affects balance, and we continued on the final 4km stretch. Highlights of this last section include a dice snake slithering through the water a couple of feet away from us, more fallen trees emphasising the clarity of the lake, which shelved steeply on this side, and stunning views of waterfall-backed, dazzling blue depths as we climbed into the leafy forest above Milanovac, Gavanovac and Kaluđerovac on a high path parallel to the lakeside route we’d taken that morning.

We reached a viewpoint overlooking the curving boardwalk that crosses the pale turquoise water to Veliki Slap, which was now suffused with a long, moving string of ant-like people. This vantage point gave us a new perspective over the tiered series of green-and-white-dammed lakes stretching up the valley, and it seemed impossible that the high, pale limestone walls on the opposite bank could hold the weight of the immense leafy forest that climbed towards the sky like a long, green afro. Returning to the entrance above that first-described view of Veliki Slap was like being struck by déjà vu, or suddenly remembering a striking dream. I thought that if, even I’d looked over that verdant, rocky, watery basin a thousand times, I’d never not be awestruck.

We tore ourselves away from the view and after a quick peruse of the gift shop, we returned to the car. I expressed my disproportionate fury at paying for seven hours’ parking despite being just a couple of minutes over six, and we started the drive back to Starigrad at 1:30pm.

Journey back to Starigrad

On the return journey, we were astonished by the beautiful countryside that had been concealed by the morning’s fog. For some reason I’d thought the landscape would have been quite arid, but the lush fields, swathes of forest and abundance of shrubs and wildflowers revealed my naivety. Rolling hills and yellow-green meadows all around us were backed by the undulating, forest-covered Velebit mountains, which stretched in a wide panorama across the horizon ahead. Remote farm buildings were scattered thinly across the countryside and we drove past lots of quaint little roadside stalls selling homemade cheese and honey.

We passed through a couple of peaceful-looking villages containing stone churches, several hotels and large buildings painted pastel orange and yellow, guessing nervously at the uncertain speed limit. At the risk of sounding like a naïve British tourist (again), I thought it looked very “European”, not dissimilar to parts of France or Switzerland. We joined the motorway and cruised back to Starigrad, enjoying mountain views the whole way, Ryan’s driving confidence having soared to the point he was willing to overtake the occasional car and sing merrily (if poorly) as the road snaked into the now-familiar little town.

We picked up a couple of supplies from the supermarket and returned to the apartment, where we relaxed for a couple of hours, making the most of the air con. We had our customary dinner of cheap, tasty slop, this time a rudimentary paella with rice, fake sausage and tomato sauce, then headed into town for a swim.

Evening: sea swim and surprise street party

We walked all the way along the pretty seafront, past the market by the main quay, and stopped on a concrete block jutting into the water between small, stony beaches backed by a leafy walkway and a little seafront campsite. I swam around while Ryan watched a snorkeler collect clams and stash them on the beach under (presumably) his mother’s straw hat. The sun dropped into the sea at the foot of the dark, jagged Velebit ridge that stretched behind the town, casting a soft orange glow between the deep, textured blue of the water and the smooth pastel sky. It was indescribably tranquil.

When the sun disappeared, we walked up a quiet street past rustic stone and whitewashed houses, then headed back to the town centre via the main road. It was a very homely place: washing hung in colourful lines from the verandas of terracotta-rooved houses, small, cosy restaurants served pizza and seafood, children of all ages played football in a small, fenced sports court and people congregated in little groups on the pavement, laughing and smoking.

Back at the main quay, which we’d only seen quiet and still under a hot sun, we stumbled into what felt like a random, Wednesday night street festival. It was 9pm but the seafront was alive with lit-up stalls selling all kinds of peculiar little gifts and edible treats. Open-fronted restaurants served food and drink to tables that had popped up across the walkway and people milled around everywhere. We bought a curly fried potato on a stick, which was spicy, salty and greasy but in a delicious way, and listened to an excellent live band that had popped up on a small seafront stage. Children and adults danced to the music and people wandered around left, right and centre with ice creams, pushchairs and dogs on leads. We finally felt like we understood the culture, and it was so charming.

We’d have liked to stay all night, but had ambitious designs on the towering vertical face of Anića Kuk in Paklenica National Park the following day. It would be our first “big wall” climb and we knew that it’d require a good night’s sleep, so we left the party after half an hour. We returned to the apartment, packed our rucksacks and went to bed feeling a strange mix of extreme contentment after our wonderful day, and intense anticipation for what we knew was to follow – “an epic”.
