Pliva Lakes

Two kilometres northwest of Jajce, the Pliva river widens into a pair of lakes — Malo Plivsko Jezero (Small Pliva Lake) and Veliko Plivsko Jezero (Large Pliva Lake) — that together form one of the most serene natural settings in central Bosnia. The Small Lake is famous for a cluster of medieval wooden watermills that stand at its outflow, their stilted structures built directly over the rushing water, and which have become one of the most reproduced images in Bosnian travel photography. The Large Lake, stretching several kilometres through a limestone valley, is largely undeveloped and excellent for swimming from June through August.

Getting to the Pliva Lakes

The lakes are accessed from the road northwest out of Jajce toward Banja Luka (the M-16.1). After crossing the town waterfall bridge, bear left and follow the lakeside road. There is a car park near the mill complex at the Small Lake outflow. The entire area is walkable from Jajce old town in about 25 minutes on foot, or 5 minutes by car.

A guided excursion taking in Jajce, Travnik and the Pliva watermills covers the mills as part of a full central Bosnia day from Sarajevo, with a local guide explaining the history of the mills and their place in Bosnian rural life. This is the most efficient way to see the lakes alongside the town’s fortress and the Jajce waterfall.

The watermills of the Small Lake

The mill complex (mlinice) at the outflow of the Small Lake clusters a dozen or so wooden structures on a narrow strip of land between the lake surface and the fast-running channel below. Most are built on short wooden stilts directly over the water, with waterwheels operating on the current beneath. Some mills are privately owned and operational; during the summer tourist season a few grind grain on demonstration for visitors.

The photographic angle most commonly reproduced shows the mills reflected in the still lake surface, with the surrounding limestone cliffs and forested ridge as backdrop. Morning light from the east illuminates the scene best, particularly in May and June before the trees fully block the sky. Entry to the mill area is free from the lakeside path; there is a small charge (2 BAM) to access the mill owners’ private terrace.

The Jajce watermills guide traces the history of the mills from their medieval origins and explains which of the surviving structures are oldest.

Swimming in the Large Lake

The Veliko Plivsko Jezero is 3.5 kilometres long and up to 1.5 kilometres wide, filling a karst depression that was enlarged when the Pliva dam was constructed in the 1950s. The water is clear and cold in May, warming to a comfortable swimming temperature by late June. The best swimming spots are on the southern shore near the outflow; there are no formal beaches but several gravelly banks that local families use throughout the summer.

The lake has no commercial beach infrastructure — no sunlounger hire, no café on the waterfront. Bring your own food and water. The road along the southern shore is unpaved in sections but passable by car; a gravel track circles most of the lake for cyclists and walkers.

The Pliva waterfall (in Jajce town)

The Pliva waterfall itself is technically within the Jajce municipal boundary rather than at the lakes, but the two are part of the same hydrological system: water from the Pliva Lakes flows down through the town and over the 21-metre travertine drop at the edge of the old town. Our Pliva waterfall guide covers the falls in detail and explains how the travertine barrier formed. The falls are best visited before or after the lakes — together they form a coherent natural circuit that takes a comfortable half-day.

Combining with the broader day

Most visitors combine the Pliva Lakes with Jajce (see the fortress and waterfalls) and Travnik (Ottoman fortress, the Šarena džamija mosque, the Andrić museum) in a single long day from Sarajevo. The standard sequence is: Travnik in the morning, Jajce town and fortress in early afternoon, Pliva Lakes and mills in late afternoon before the return drive.

A day that includes all three can be long (12-13 hours return from Sarajevo) but is doable and rewarding. The Jajce, Travnik and Pliva waterfall day trip runs this circuit from Sarajevo with transport and guiding included.

Practical tips

• The mill area is best before 09:00 or after 17:00 to avoid coach groups that arrive mid-morning.
• The road around the Large Lake can be very quiet in the evening — a good time for a sunset drive along the water.
• There are no accommodation options at the lakes themselves; stay in Jajce or make this a day trip from Sarajevo.
• The Pliva river supports trout; local restaurants in Jajce serve fresh river fish that originates from the lake system.
• In early June the meadows around the lake margins are full of wildflowers — a particularly attractive time to visit.

The Pliva Lakes are not the most visited destination in Bosnia, which is precisely their appeal. A short detour from one of the country’s most interesting medieval towns, they offer swimming, mill photography and a quiet natural landscape that feels entirely off the standard tourist circuit.
