Eighteen glittering glacial lakes known as gorske oči (mountain eyes) dot the Durmitor range. The spectacular Black Lake, a pleasant 3km walk from Žabljak, is the largest of them and the most visited part of the national park. The rounded mass of Međed (the Bear; 2287m) rears up behind it, casting an inky shadow into the pine-walled waters. An easy 3.6km walking track circles the lake.
