Durmitor is a limestone massif in northern Montenegro whose western edge falls away into the Tara River Canyon — at 1,300 metres, the deepest gorge in Europe. The Ice Age did the carving: glaciers ground the rock into forty-eight peaks above 2,000 metres, crowned by Bobotov Kuk at 2,523 metres, the highest summit lying entirely within Montenegro. As the ice withdrew it left eighteen lakes scattered across the high slopes, which locals still call gorske oči, the "mountain eyes." Far below, the turquoise Tara foams white between walls of pale limestone.
The best loved of those eyes is Crno jezero, the Black Lake, an easy three-kilometre walk from the town of Žabljak. It is really two lakes joined by a strait that shrinks each summer. On a windless morning the water lies flat enough to mirror the pyramid of Međed peak and the dark spruce that give the lake its name. Downstream, the Đurđevića Tara Bridge arcs 172 metres above the river; when it was finished in 1940 it was the largest vehicular concrete arch bridge in Europe, and it did not stay intact through the war. In summer the meadows fill with wildflowers and rafters ride the cold Tara through the gorge. In winter the snow settles deep and Žabljak, the highest town in the Balkans, becomes a ski resort. Still a working national park, Durmitor rewards a slow visit — one lake, one ridge, one season at a time.
