What to see at Plitvice Lakes: the Great Waterfall and Kozjak

Most people arrive at Plitvice expecting scenery and leave having seen scenery, which misses the actual subject. The lakes exist because the water here is saturated with calcium carbonate, and where mosses and algae grow in the current, the mineral crystallises onto them and hardens. That builds barriers, the barriers hold back water, and the water forms a lake. The process has not stopped: the dams grow roughly a centimetre a year, so the park you walk through is a landscape still under construction. UNESCO listed it in 1979 for exactly this reason.

Lower lakes: the Great Waterfall and the canyon

The four lower lakes sit in a limestone canyon and end at Sastavci, where the Plitvica stream drops 78 metres as Veliki Slap, the tallest waterfall in Croatia. This is the postcard, and the viewpoint above the canyon near Entrance 1 gives the wide version while the boardwalk at the bottom gives the loud one. Do both, they are twenty minutes apart. On the way, the Šupljara cave opens directly above the boardwalk and you can walk up through it; German visitors often recognise the surroundings, because Karl May adaptations were filmed here in the early sixties.

• Tickets are timed and sold through the official park webshop. Validate at the entrance and in the slot you booked, not another.
• Swimming has been prohibited throughout the park since 2006. The barriers are living formations and are damaged by contact.
• The boardwalks have no railings in long stretches and get slippery when wet. Closed shoes with grip, and hold small children.
• Drones are banned, and so is leaving the marked boardwalks anywhere in the lake system.

Upper lakes and the crossing of Kozjak

The twelve upper lakes lie on softer dolomite, so they are wider, shallower and more open than the canyon below, with waterfalls spreading sideways rather than dropping in one line. Galovac and its cascades are the section most worth slow walking. Between the two halves sits Kozjak, the largest lake, crossed by a quiet electric boat that is included in the ticket and doubles as the only real rest on a long day. If you have to choose one half, take the lower lakes for drama and the upper lakes for water you can actually look into.

Plan a full day and start with the first slot of the morning, both because the light on the water is better and because the boardwalks are single file and fill up. Spring carries the most water, autumn the best colour, and winter turns parts of the system to ice with far fewer people. If you stay overnight nearby, Rastoke with its watermills built into the river is twenty five minutes north and makes an easy second stop.

How to get there

The park lies inland on the D1 road between Karlovac and Korenica. Zagreb and Zadar airports are both about 130 km away, Split 250 km. From Zagreb you take the A1 motorway to Karlovac and then the D1 south, about 2 hours. Zadar is about 1 hour 45 minutes, Split about 3 hours with motorway tolls of around 20 euro each way. Buses from the Zagreb main bus station stop on the D1 at both entrances, so tell the driver which one you want. Car parks at both entrances open at 07:00 and charge by the hour in summer.

Which entrance and which programme

Entrance 1 at Rastovača is the northern one, nearest the Great Waterfall, and in 2024 it took 61 percent of arrivals, so the morning queue forms there. Entrance 2 at Hladovina lies a few kilometres south on the same road, beside the park hotels, and opens onto the Kozjak dock and the upper lakes. Starting there in July and August means walking instead of queuing for your first hour. The panoramic train leaves from Station 1 next to Entrance 2, and Station 3 at the far end is the nearest stop to Prošćansko. Choose a lettered programme from the park map before you arrive.

• A, Entrance 1: lower lakes and the Great Waterfall only, 3.5 km, 2 to 3 hours, the short version for small children.
• B, Entrance 1: lower lakes, boat across Kozjak, train back, 4 km, 3 to 4 hours, the standard day trip.
• C, Entrance 1: lower and upper lakes with boat and train, 8 km, 4 to 6 hours, the full day.
• E, Entrance 2: upper lakes only, train up and boat back, 2 to 3 hours, the quiet summer option.
• K, either entrance: the full circuit of all 16 lakes on foot, about 18 km, 6 to 8 hours, no shortcuts.

How busy is it, really

The park recorded roughly 1.49 million visitors in 2024, from around 163 countries, with July and August as the peak months. The mix was 79 percent adults, 13.7 percent children aged 7 to 18 and 7.3 percent students, and 85 percent of visitors came from abroad. By origin, 77.7 percent were European, 12.8 percent came from Asian markets and 6 percent from the USA and Canada; after Croatia itself, Germany, Poland, France and Italy led the country ranking. The park also sold 149,156 accommodation nights in its own facilities, 93 percent of them to international guests.

The Lower Lakes canyon in detail

From Entrance 1 the steps drop into the canyon and in a few minutes reach the viewpoint above the lower chain, where the 4 lakes are seen following each other in steps. The platform is small and railed, so a queue forms from mid morning. The path continues to the bridge below Veliki Slap, where the Plitvica stream falls 78 metres from the side, then to the bridge over Sastavci, where the last lake spills into the Korana and the spray is heavier than anywhere else in the park. In August the Great Waterfall thins to slender jets, so the canyon walls and the colour of Milanovac carry the scene. The walkway then runs upstream through Novakovića Brod, Kaluđerovac and Gavanovac to Milanovac and dock P1. A side path enters Šupljara cave, about 60 metres long, narrow and wet, and comes out above the canyon a few minutes below the viewpoint. Allow 90 minutes to 2 hours, with climbs.

The Upper Lakes walk in detail

From Entrance 2 the panoramic train leaves Station 1 and reaches Station 3, the far stop near Prošćansko, in about 15 minutes. From there the path descends all the way. It begins at Labudovac, where the water from Prošćansko drops some 20 metres into Okrugljak and the path passes through spray beside a cave under the barrier. Batinovac and Vir follow, with mirror surfaces on still mornings. At Galovac the walkway passes below Veliki and Mali Prštavac, then crosses the barrier itself between a dozen separate streams above Galovački buk, the slowest stretch of the upper chain after 10:00. Gradinsko comes next, shallow and full of reeds and birds, then the Burgeti pools, and the walk ends at dock P2. Count 2 to 3 hours on foot before the boat across Kozjak to P1 and the Lower Lakes.

Tickets, prices and opening hours

Ticket prices follow the season and are the clearest guide to crowds. The summer prices, 1 June to 31 August, are in the table below; outside the summer the same adult day ticket costs 23 euro in April, May, September and October and 10 euro from November to March. Children under 7 enter free in every season.

Two other options are worth knowing. A two-day ticket, valid June to September, costs 60 euro for adults, 40 for students and 20 for children aged 7 to 18. Groups of at least 15 people get 1.50 to 2 euro off per adult or student ticket. Guided tours are priced separately at 120 euro for a half day and 170 for a full day, and car parking in peak season is 2 euro per hour.

There are 2 quiet windows: the first 2 hours after opening, when Milanovac and the canyon viewpoint are almost empty, and the period after 16:00, when the coaches have left and the cheaper afternoon ticket from the price table applies. The afternoon ticket suits one lake system walked slowly, the Lower Lakes from Entrance 1 or the Upper Lakes from Entrance 2.

Where to stay

For an early start, sleep within walking distance of an entrance. The park hotels stand at Entrance 2, and Mukinje next to them was built after 1950 for park staff, with a shop and restaurants that fill after the loop. Plitvica Selo sits above the canyon of the Great Waterfall near Entrance 1, and most of its houses are now rooms and apartments. Korana village, a few kilometres north where the river leaves the canyon, is quieter, with old stone and timber houses now run as guest houses. Korenica, 10 km south, is the nearest town with full shops and services.

Food and supplies

Inside the lake system food is limited to kiosks at the entrances and the Kozjak docks, so bring water and lunch. The shop in Mukinje is the nearest to Entrance 2 for bread, fruit and drinks. Rakovica, north of the park, has a small market on the main road selling potatoes, cabbage and beans from the gardens around, apples and plums in autumn, Lika cured meats and sheep's and cow's cheese. Roadside restaurants along the D1 serve spit-roasted lamb, the standard Lika meal, and trout from the local rivers.

What to bring

Past the entrances the lake zone has few services. There are kiosks at the docks, a restaurant at dock P2 and another at Entrance 2, toilets at the docks and a cloakroom at Entrance 1 for anything you do not want to carry. The Upper Lakes are shaded by beech and fir, but the Lower Lakes canyon and the boat crossing are open to the sun, and in August the afternoons are hot. The list below covers a full day on the longer routes.

• At least 1 litre of water per person, since the kiosks stand only at the docks and entrances and the long routes pass nothing between them.
• A packed lunch, because the tables at dock P2 are the only place to sit and eat inside the lake zone and they fill at midday.
• A light waterproof layer for Sastavci and the Prštavac falls, where spray reaches the boardwalk even on a dry August day.
• A hat and sun cream for the Lower Lakes canyon and the boat crossing, which are open to the sun from late morning.
• A lens cloth, because mist from the falls settles on camera glass and phone screens within seconds.
• A small bag only, as the boardwalks are narrow and a wide rucksack blocks the single-file stretches at Milanovac and Galovac.

With children

Children under 7 enter free and those from 7 to 18 pay a reduced rate. Pushchairs do not work on the boardwalks or on the stair sections of the Lower Lakes, so bring a carrier for small children. Long stretches of walkway have no railing and the water is close, which means holding hands at the narrow points. Programme A from Entrance 1, 3.5 km and 2 to 3 hours, is the usual choice for a family, and the boat and train break up the walking. Šupljara cave is popular with older children but is narrow, wet and ends in a climb. Outside the park, the adrenalin park has low rope courses for children, the Speleon centre in Rakovica has cave models to touch and does not depend on the weather, and Ranch Deer Valley, about 20 minutes' drive, lets children feed deer under supervision if you book ahead.

Day trips within 20 km

The Barać caves at Nova Kršlja, about 15 km north near Rakovica, were among the first caves in Croatia laid out for visitors, with paths and lighting installed at the end of the 19th century. Drežnik Grad, about 20 km north on a rocky spur above the Korana canyon, is a fortress raised in the 13th century to control the road from Lika, and it lies directly on the way in from Zagreb. East of the park Gola Plješivica, 1,649 metres, stands on the border with Bosnia and Herzegovina, so keep to the marked trails and carry your passport.

The places, one by one

Lower Lakes Viewpoint

The viewpoint stands on the lip of the limestone cliff above the canyon, and it is the one place where you see the lower chain as a staircase: Milanovac, Gavanovac and Kaluđerovac with the barriers between them, and at the bottom Sastavci and the Great Waterfall, all in a single frame. You reach it by a forest path or by climbing through the Šupljara cave, a few minutes either way. The platform is small and railed, so in summer a queue forms and you wait your turn. Go before noon, when the sun reaches the floor of the canyon and the water shows its colour.

Sastavci Waterfalls

Sastavci is the point where all the water of the Plitvice chain meets. From Novakovića Brod, the last lake, it spills over a run of cascades, and from the side the Great Waterfall crashes into the same hollow. Below that meeting the river Korana begins and flows north into its own limestone canyon. The name means the joining of waters. A wooden bridge crosses the falls and gives you the whole scene at once, and steps nearby climb back toward Entrance 1. After rain there is more spray here than anywhere else in the park, so cover your camera and phone before you step onto the bridge.

Novakovića Brod Lake

Novakovića Brod is the last and lowest lake in the chain, at about 503 metres above the sea, some 130 metres lower than Prošćansko at the top. It is small and shallow, ringed by the canyon walls, and its water leaves through Sastavci into the Korana. The name comes from brod in the old sense of the word: a place where a river could be forded, because the water here was shallow enough to cross. A walkway runs through the lake and over the barrier, ending at the bridge below the Great Waterfall. From here steps climb toward Entrance 1, or the path continues along the Korana toward the way out of the canyon. By now you have walked the whole drop of the chain.

Lake Kaluđerovac

Kaluđerovac fills the narrowest part of the lower canyon, directly under the vertical cliff in which the Šupljara cave opens. The name comes from kaluđer, a monk, after a hermit who by tradition lived in that cave. The lake is deep and dark green, and because the cliff shades it for most of the day the colour shifts between dark blue and emerald. At its lower end the water passes into Novakovića Brod, the last lake, at about 503 metres above sea level and 130 metres below Prošćansko. The boardwalk takes you along the cliff foot and over the water, and steps to the side climb to the cave mouth.

Lake Gavanovac

Gavanovac lies between Milanovac and Kaluđerovac, with a barrier that lets the water down in several broad curtains. Its name is tied to the story of the rich Gavan, told in these parts in several versions: he refused to help a beggar, so his estate sank and a lake formed on the spot. Legends of drowned manors are common in karst country, where water really does vanish underground. The lake is shallow and very clear, with tufa deposits visible on the bottom. The walkway runs along its edge, and off to the side the mouth of Šupljara cave shows in the cliff above. This is the place to look at the bottom: the white deposits are the barriers of the future.

Lake Milanovac

Milanovac is the first lake below Kozjak and has the strongest colour in the lower chain, deep green to turquoise depending on the light and on how much dissolved limestone the water carries. It lies in a narrow stretch of the canyon, ringed by cliffs and by forest that reaches the water, and the barrier at its end drops the water toward Gavanovac in a run of cascades. The boardwalk crosses the lake just above the surface, so you look straight down onto drowned trees and shoals of fish. The passage is narrow and a crowd builds here in summer. It is quietest in the first 2 hours after the park opens.

Lake Kozjak

Kozjak is the largest of the lakes, about 82 hectares in area and up to 47 metres deep, and it divides the Upper from the Lower Lakes. It formed when 2 lakes merged as the tufa barrier between them grew high enough to raise the water level, and the drowned old barrier can still be seen below the surface, stretching across the lake. The water is cold all year and markedly green from the dissolved limestone. On a peninsula reaching into the lake stand the remains of Krčingrad, a fortification from the late Middle Ages abandoned after the Ottoman incursions of the 16th century and the only trace of human building in the lake zone. It has no arranged access, so look for it from the boat.

Kozjak Boat Dock P1

Dock P1 sits at the northern end of Kozjak, on the lower lakes side, and it is the busiest spot in the park because routes from both directions meet here: walkers up from the Great Waterfall wait for the boat south, and those who have finished the upper lakes step ashore. Beside the dock are a shelter, benches and a kiosk with drinks. The crossing takes about 15 minutes and the boats run at short intervals through the season, but in summer you can wait some 20 minutes for a place. A shore path leaves from here toward the lower lakes with no climb at all.

Kozjak Boat Dock P2

Dock P2 is the southern landing, nearer the upper lakes, where boats from the north put you ashore and the path along the upper chain begins. From here you walk toward the Burgeti and Gradinsko, and further upstream to Galovac and Prošćansko. The dock has a restaurant, toilets and a rest area with tables, one of the few points inside the lake system where you can sit down and eat. The boats run at short intervals in season and less often in winter. The wait here is usually shorter than at the northern dock, so this is the better place to time a break around the crossing.

Gradinsko Lake

Gradinsko is one of the last lakes in the upper chain before Kozjak and looks different from its neighbours: shallow and largely overgrown with reeds. That makes it the best place in the park for birds. Ducks, grebes and herons nest in the reeds, and dragonflies hunt over the open water. The name comes from gradina, a hillfort, because the remains of a medieval fortification lie on a peninsula in the lake. The water leaves toward Kozjak over the Burgeti, a web of tiny pools separated by tufa rims only a few tens of centimetres high. The boardwalk passes through the reeds just above the surface. Come early in the morning for the birds.

Veliki Prštavac Falls

Veliki Prštavac is one of the strongest falls in the upper chain. The water drops over a high barrier into Galovac in a broad curtain that you hear well before you see it when the flow is up. The name comes from prštanje, the sound of water striking stone and breaking into droplets. The boardwalk passes directly below it, tight against the rock, and you walk through the spray on wet boards. Mali Prštavac stands beside it on the same barrier, lower and narrower, and the walkway threads between the two. Early in the morning this stretch is nearly empty and the spray often catches small rainbows. In summer the flow divides into a few thinner jets.

Pevalekovi Waterfalls

The Pevalek Falls carry the name of Ivo Pevalek, a botanist who in the years after 1918 studied how the Plitvice tufa forms. He showed that it is a living process depending on mosses, algae and the composition of the water, and his work was the main argument for protecting the area and for the proclamation of the national park in 1949. The falls lie in the upper chain on a barrier that descends in several broad steps overgrown with moss, and the path passes right beside them. What you see is exactly what he described: plants catching the limestone from the water and turning it to stone. The flow is greatest in spring. Stop and look at the edges of the steps, where the new stone forms.

Labudovac Waterfall

Labudovac is one of the highest falls in the upper chain. Water leaving Prošćansko crashes over a broad tufa barrier some 20 metres down into Okrugljak in several separate jets. Below the barrier a cave has been hollowed out by the water, and the path passes right beside it, so you walk through the spray. This is the clearest place in the park to watch tufa growing: mosses catch the limestone from the water, turn to stone and build a new sill. Okrugljak below took its name from its rounded shape, unusual in a chain of long, narrow lakes. The fall is strongest in spring, when snow melts on the Lika plateau, and thins to a few jets in summer.

Ciginovac Lake

Ciginovac is the second lake in the upper chain, directly below Prošćansko, and one of the quieter places in the park, because the main paths run along the forest edge above it. Dense beech forest surrounds it and gives the water a dark colour. It lies under the slope, so it sits in shade for most of the day and the surface is usually still enough to mirror the trees. Its water spills over a low tufa barrier toward Okrugljak. A path from the upper entrances leads down to it, a walk of some 20 minutes. Come here to see what the landscape looks like without the crowd: forest, water and the sound of water, and little else.

Prošćansko Lake

Prošćansko is the first and highest lake in the chain, at 636 metres above sea level, and the second largest in the park after Kozjak. It is fed by the Crna and Bijela rivers, which meet just south of the lake and carry water down from the forests of the Lika plateau. Everything below starts here. The lake is long and narrow, ringed by beech and fir forest mirrored in the water, and its shore is mostly unbuilt and quiet because the main routes turn downstream before they reach it. A path from the upper entrances takes you to it past several viewpoints. Fewer people come here than anywhere else in the lake system.

Lakeside Boardwalks

The wooden walkways are the main way of moving through the lake zone. There are about 18 km of them in all, running over the water, along the edges of the barriers and through the shallow parts of the lakes. They are built of timber from the surrounding forests and renewed regularly, because damp and tufa wear them quickly. Tufa also settles on the boards, so stretches of walkway grow into the ground over time. On most sections there are no railings, and that is deliberate: railings would block the view and speed up decay. In season you walk in a single direction, following the markings, so once you have passed a point you do not go back to it.

Adrenalin Park Plitvice

The adrenalin park near Plitvice is laid out in the forest, with rope courses, small bridges and platforms fixed between the trees at different heights. The courses are graded, from low ones for children up to routes 10 metres above the ground that need real strength and balance. Everyone wears safety gear, and an instructor explains the harness and pulley before you start. Beside the courses there are a zipline and a climbing wall. It suits the afternoon after a morning on the boardwalks, since inside the national park nothing is allowed except walking the marked paths. The park is open from spring to autumn, and groups should book ahead.

Zipline Beware of the Bear

The zipline near the park is strung across a forest hollow, with steel cables stretched between 2 slopes, so the flights run above the treetops and a stream. The name plays on the fact that the brown bear really does live in these forests, one of the largest populations in this part of Europe, though the animals avoid people and are seldom seen. Guides explain the gear and the braking before the start, and each leg lasts a few dozen seconds. There are weight and age limits, and in heavy rain or wind there are no flights. It works from spring to autumn and arrival is arranged in advance. It fits an afternoon after a morning on the Lower Lakes.

Ranch Deer Valley

Ranch Deer Valley lies about 20 minutes' drive from the park entrance and shows what a working farm in the Lika hinterland looks like. Red and fallow deer are kept in fenced pastures and you may feed them under supervision. The horses are used for riding and for cart rides along the forest tracks around the ranch. The hosts also serve food prepared in the traditional way, mainly lamb and cheese from this region, so it doubles as a place to eat properly after the lakes. Because animals are involved, you arrange your arrival in advance, and riding has age and weight limits. Check those before you promise children a ride.

Speleon Centre

Speleon is an exhibition space in Rakovica, on the main road toward Plitvice, built as a reconstructed cave that you walk through. The display explains how passages, halls and formations form, how water dissolves limestone and how slowly a stalactite grows. It also shows the cave bear, bats and the small invertebrates of the dark, among them species found only in the Dinaric karst, such as the olm. Children get models they are allowed to touch. The visit takes about 40 minutes and does not depend on the weather, which makes it the obvious plan for a wet morning. It pairs well with the Barać caves nearby.

Rastoke Watermills

Rastoke stands north of Plitvice at the point where the river Slunjčica meets the Korana, one of the few villages built directly on waterfalls. The Slunjčica drops over tufa sills in dozens of small falls, and the houses sit on the rocks between them, with water running under the floors. That water once drove mills and fulling stamps for cloth, more than 20 of them at the peak, and several have been restored and run as demonstrations. You walk the settlement on paths and small bridges with a ticket, and about 1 hour is enough. It lies on the road from Karlovac, so it fits as a stop on the drive in from Zagreb.

Drežnik Old Town

Drežnik Grad is a medieval fortress on a rocky spur above the canyon of the Korana, some 20 km north of the park. It was raised in the 13th century by the counts who held this part of Kordun, on a site chosen to control the road from Lika toward the Kupa basin. In the 16th century it stood on the line of defence against the Ottoman Empire as part of the Military Frontier and was rebuilt and strengthened several times. After the border moved it lost its purpose and fell into ruin. Today the walls, the foundations of towers and the entrance are visible, with paths and explanatory panels on part of the site, and the river shows far below. Access is free.

Gola Plješivica

Gola Plješivica is the highest peak of the range east of the park, at 1,649 metres, and the state border with Bosnia and Herzegovina runs across the summit. The top is bare of forest, which is where the name comes from, and on a clear day you see the whole of Lika, the Plitvice valley and part of the Una. Inside the mountain lies an abandoned underground military complex from the Yugoslav period, one of the largest of its kind in Europe. Entering is dangerous and forbidden because of uncleared minefields. The climb follows marked paths and is advised only with a guide. Stay on the marked ways, carry an ID document because the summit lies on the border, and check the weather before you set out.
