Black Lake (Crno jezero) is the largest of the 18 glacial lakes of Durmitor National Park, 3 km south-west of Žabljak in northern Montenegro: 0.52 km² of water at 1,418 m, up to 49.1 m deep, ringed by spruce forest under the peaks of the Durmitor massif. It is the busiest place in the park and the easiest to visit: a flat path of about 3.5 km circles it in an hour, rowing boats are for hire from the ranger, trout fishing is allowed on the large lake from May to October, and most of the marked mountain trails, including the way up Bobotov kuk, start on its shore. The park ticket is €5 a day, free for children under 15.
Two lakes in one
The name covers two basins, Veliko jezero (the large lake) and Malo jezero (the small one), joined by a narrow strait. In a dry summer the strait disappears and the two stand apart. Snowmelt, springs such as Čelina and waterfalls that run only in spring feed the lake; it has no visible outlet. The water drains underground and, unusually, reaches two river systems at once, the Tara and the Piva. In winter the surface freezes.

The lake lies at the edge of the Durmitor plateau, which averages 1,450 to 1,500 m, below the central ridge of Savin kuk, Šljeme and Bobotov kuk (2,522 m). The lake lies at 1,418 m (the park gives 1,416 m). Durmitor has been a national park since 1952 and a UNESCO World Heritage site since 1980, and the lake is its main checkpoint and busiest zone. The lakes of Durmitor hold only introduced fish: here brown trout, rainbow trout and Arctic char.
Walking round the lake and beyond
The lakeside path is the park's educational trail: 3.5 to 3.6 km, flat, about an hour at an easy pace. A reading forest with deckchairs stands near the visitor centre at the start. Longer walks branch off it:

- Tri jezera (Three lakes) loop from Black Lake: 8.93 km, 172 m of climbing, graded easy.
- Barno jezero, Zminje jezero and back to Black Lake: the park's short forest loop.
- Black Lake to Stari katun (Lokvice) and the Ledena pećina ice cave: the route towards the central peaks. The Lokvice shelter at 1,800 m sleeps up to 20 people and is open all year.
- Žabljak, Lokvice and Bobotov kuk: the classic ascent of the park's highest peak starts here.
- In winter a marked snowshoe trail runs 6.7 km from the Savin kuk ski centre to the lake, about 2 hours one way. Snowshoes cost €4 a day and poles €3 a day from the park; bikes are €3 an hour or €8 a day.
The Durmitor hiking page lists the 25 marked trails of the park, about 150 km in all; the hiking hub covers the rest of Montenegro.
Boats and swimming
Wooden rowing boats and kayaks are rented from the park ranger on the shore: €10 an hour for a boat, €5 an hour to launch your own. Swimming is not organised: there are no lifeguards and no marked bathing area, but the water reaches about 20 °C in summer and people swim from the shore.

Fishing
Sport fishing is allowed from May to October on Veliko jezero only; Malo jezero is closed to fishing. A daily permit (€20) is bought from the ranger on duty, who also sells the boat hire. Fishing hours are 14:00 to 19:00, every day except Monday, with one rod and artificial lures only; the limit is four trout a day with a minimum size of 25 cm, and the park recommends catch and release. The national fishing order adds a closed season for all trout in Žabljak municipality from 1 November to 15 March, and any fish caught in a closed season goes back alive. The fishing hub covers permits on the Tara and elsewhere.
