Black Lake is a lake in the municipality of Zabljak, in northern Montenegro. It is a glacial lake, located on the mountain Durmitor, at an altitude of 1416 m. It is located 3 km from the town of Zabljak. Black Lake lies at the foot of the peak Medjed and has an area of 0.515 km2. The lake consists of two smaller lakes, Big and Small Lakes. These two lakes are connected by a narrow stream and thus form two separate water bodies. The Great Lake has an area of 0.338 km2, a maximum depth of 24.5 m, a maximum length of 855 m and a maximum width of 615 m. The small lake has an area of 0.177 km2, a maximum depth of 49.1 m, a maximum length of 605 m and a maximum width of about 400 m. The greatest length of the entire Black Lake is 1155 m. The small lake actually has a larger volume than the large one, due to the greater depth. Numerous mountain streams flow into Black Lake, and the most famous is Mlinski potok. Other streams do not have a name, as they appear periodically, when the snow from Durmitor melts. Black Lake is the main tourist attraction of the Durmitor region. It is the largest and most famous of the 18 glacial lakes on the mountain. The lake is accessible, and can be reached on foot from the center of Zabljak. 3.5 - {km} - hiking trails stretch around the lake, and it is a popular recreational destination.
