Your adventure snapshot

The plateau lakes of Zelengora.

Zelengora is the mountain plateau that rises above the Sutjeska River Valley — a wide, open landscape of alpine meadows and glacial lakes at around 1,400–1,500 metres. It is one of the most biodiverse alpine environments in the western Balkans, with over 300 plant species recorded across the plateau, and the two Zelengora lakes are the still heart of it.

Orlovačko Lake sits at 1,438 m and Jugovo Lake at 1,450 m — both glacial, both clean enough to swim in and both set against a backdrop of open sky and the Stog summit above. The trail between them is easy and well-marked. The pace of the day is slow by design: 3–4 hours at the lakes for swimming, lunch on the shore and time to sit in a place that most travellers moving through the region never reach.

This is one of the most accessible tours we run — suitable for families with young children, no hiking experience required, and the trail to the lakes is gentle enough for anyone walking comfortably.

What makes the Zelengora plateau different

Orlovačko Lake at 1,438 m

The first lake you reach on the Green Trail — a wide, calm glacial lake with clear water and open views across the plateau. The name means "Eagle Lake" and the banks are flat and accessible. Swimming is possible from June through September and the water, while cold, is clean and refreshingly clear after the walk up.

3–4 hours at the lakes

The day isn't built around a destination and a return march — the pace stops at the lakes. Time to swim, eat lunch on the shore, walk between the two lakes at a relaxed pace and sit in the alpine meadows. The guide identifies plants and explains the ecology of the plateau for anyone interested. No rush to be anywhere.

Biodiversity of the Zelengora plateau

Over 300 plant species have been recorded on the Zelengora plateau — rare alpine flowers, endemic grasses and medicinal herbs that grow across the open meadows between the lakes. The guide walks with the group and points out what is underfoot. June and July are the peak flowering months, but the meadows are distinctive right through the summer.

Stog summit in view

Stog (1,970 m) rises above the southern edge of the Zelengora plateau and is visible from both lakes on a clear day. The peak itself is not part of this tour — this is a day at the lakes, not a summit route — but the presence of the mountain above gives the plateau its character. The view across the meadows towards Stog is the one that appears on most photographs of Zelengora.

From there the trail rises gently through alpine meadows to Orlovačko Lake, continues to Jugovo Lake, and returns the same way. Three to four hours at the lakes for swimming, lunch and time in the meadows. Return to Tjentište by early evening.

Dates & availability

Available June through October

The Zelengora plateau is accessible from June through October. June and July bring the peak wildflower season — the meadows between the lakes are at their most colourful. August is the warmest month and the best for swimming. September offers cooler air and fewer visitors, with the first autumn colours beginning on the surrounding slopes. Get in touch and we'll confirm the right date for your group.

The best day of our Bosnia trip. We had the plateau completely to ourselves — no crowds, no noise, just the lakes and the meadows and the mountain above. The guide knew every plant and pointed out things we would never have noticed walking on our own. The swim at Orlovačko at midday is a memory I'll keep for a long time.

★★★☆☆

Beautiful landscape and the guide was knowledgeable and kind. The lakes themselves are stunning — the water is unbelievably clear. My only note is that the day felt slightly rushed during the return and we had less time at Jugovo than I'd hoped. Worth doing, just worth communicating what pace you'd like from the start.

★★★☆☆

A lovely day in a genuinely remarkable landscape. The wildflowers in June were extraordinary — I'd never seen anything like it. The trail is very accessible which means it's a good option for families. We came expecting a more remote feeling and the plateau delivered. Good lunch, good guide, good day.
