BLACK LAKE · FOREST & GLACIAL LAKE WALK
Walk beneath the dark conifer forests of Durmitor to a glacial lake where still water, mountain reflections and the great face of Međed change with every step.
At the edge of Žabljak, a path enters the forest and leaves the town behind.
The trees open gradually, revealing dark water beneath the limestone face of Međed. On a still morning, the mountain appears twice—once above the forest and again in the reflection below.
This is Crno Jezero, the Black Lake: the largest and best known of Durmitor’s 18 glacial lakes, traditionally called the mountain’s eyes.
Despite its name, the water is rarely simply black. It changes with the weather—deep green beneath the forest, turquoise in bright sunlight, silver under cloud and almost perfectly transparent along the shore.
The lake is actually formed by two basins: Veliko Jezero and Malo Jezero. During periods of higher water, they are joined by a narrow channel. As the level falls, the connection may disappear and reveal two separate lakes with remarkably different depths.
A marked trail circles both basins, passing through conifer forest, across roots and rocks and beside small streams descending from the mountain. The standard circuit is accessible enough for a gentle outdoor day, but the experience does not need to end there.
For travellers who want to continue, quieter paths lead deeper into Durmitor—to Zminje Lake hidden beneath spruce trees, across open mountain clearings or towards viewpoints above the forest.
Black Lake may be Durmitor’s most familiar landscape. With time, local knowledge and the right route, it can still feel wonderfully personal.
The approach begins beneath tall conifers, with only brief glimpses of the mountains between the trees. Then the path reaches the open shore and the complete landscape appears at once: water, forest and the great limestone wall of Međed rising behind the lake. Rather than continuing immediately, the experience allows time to notice how light, cloud and wind alter the scene.
Crno Jezero consists of Veliko Jezero—the larger surface basin—and Malo Jezero, which is smaller but significantly deeper. A narrow channel connects them when the water is high. During drier periods, the channel recedes and the two parts become visibly separate, revealing the seasonal movement of water through Durmitor’s limestone landscape.
The circular trail leaves the busiest viewpoint behind and enters a quieter world of spruce, fir, moss and exposed roots. Each side of the lake feels different. Some sections remain close to the water, while others rise slightly through the forest or cross small streams and rocky ground.
The closer the trail moves towards Malo Jezero, the more strongly Međed dominates the view. Its name means bear, and its steep limestone slopes form one of Durmitor’s most recognisable silhouettes. From the lake, the mountain gives a first sense of the much wilder terrain hidden beyond the forest.
For groups choosing the longer route, the walk can continue towards Zminje Jezero—Snake Lake. Much smaller than Black Lake and enclosed by dense forest, Zminje has a completely different atmosphere. Its dark green water, fallen branches and exposed tree roots make it feel less like a famous viewpoint and more like a hidden part of the mountain.
The experience is deliberately shaped around more than completing a circuit. There can be time for photography, a forest picnic, stories about Durmitor’s glacial landscape and a quiet pause beside the water. When available and permitted, a seasonal boat ride can offer another perspective from the lake itself.

The standard lake circuit is relatively short, but conditions should not be judged by distance alone. Rain, snowmelt and fallen branches can make parts of the shoreline trail wet, slippery or more difficult than expected.
For travellers who want to experience Durmitor slowly, without needing to climb one of its high peaks.
The experience is particularly well suited to:
No previous hiking experience is required for the standard Black Lake circuit.
Participants should be comfortable walking on natural forest paths with roots, stones and occasional muddy sections. The complete shoreline trail is not uniformly flat or suitable for all pushchairs, wheelchairs or guests with limited mobility.
A shorter out-and-back walk can be arranged for anyone who prefers to remain close to the main shore, while stronger walkers can continue towards quieter lakes and deeper forest trails.
A relaxed half-day experience following the marked trail around Veliko and Malo Jezero. The pace is deliberately unhurried, with time for the main viewpoints, photography, interpretation of the glacial landscape and a picnic or seasonal drink beside the lake.
The route can be shortened if the group prefers an easier walk or if sections of the circuit are affected by water, ice or trail conditions.
Best for: families, couples, photographers and travellers wanting a beautiful but undemanding introduction to Durmitor.
A longer private walk beginning at Black Lake before continuing along selected forest trails towards Zminje Lake, Barno Lake or another suitable part of the national park.
The exact route depends on fitness, weather and seasonal conditions. The experience may include deeper forest, open clearings and quieter places beyond the main visitor area.
Best for: moderately active travellers who want to move beyond Durmitor’s most famous viewpoint without committing to a high-mountain ascent.
This flexibility allows Borova to shape Black Lake as either a gentle encounter with Durmitor or the beginning of a more immersive day in the national park.
Black Lake is one of the most accessible natural attractions in Durmitor, but the complete circuit remains a mountain trail rather than a paved promenade.
Tree roots, loose rocks, wet ground and stream crossings require attention. Water levels can affect sections near the shore, while snow and ice may remain in shaded parts of the forest outside the main summer season.
Weather around Žabljak can change quickly. A warm, clear beginning can be followed by rain, wind or a significant drop in temperature.
The local guide or operating partner may:
Black Lake is deep, cold and fed by mountain water. Swimming should never be treated as an automatic part of the experience and is considered only where current park rules, weather, water temperature and the guide’s assessment allow it.
Wildlife should be observed without approaching, feeding or disturbing it. All food and waste must be carried out of the park.
The responsible local partner confirms the final itinerary, guide, price, inclusions and booking terms before you reserve.
Final inclusions would depend on the personalised itinerary.
The forest can remain cool and damp even when Žabljak feels warm and sunny.
