Durmitor

A limestone massif in north-western Montenegro and the national park around it, protected since 1952 and inscribed on the UNESCO World Heritage list in 1980 together with the Tara river canyon. It covers roughly 390 square kilometres of peaks, glacial lakes and high pasture.

Bobotov Kuk, at 2,523 m, long thought to be the highest point in Montenegro until surveys gave that to Zla Kolata in the Prokletije. It is a full day's walk from Zabljak, with a scramble near the summit, and the usual objective for fit walkers.

Crno jezero, the largest and most visited of Durmitor's eighteen glacial lakes, about 3 km from Zabljak and reachable on foot. A level path circles it in around an hour, and it is the one place in the park that is busy in August.

About 1,300 m at its deepest, which makes it the deepest river canyon in Europe and second in the world after the Grand Canyon. It forms the park's northern boundary and is the reason the UNESCO listing covers river as well as mountain.

Zabljak, at around 1,450 m the highest town in the Balkans, sits inside the park and has most of the accommodation, from hotels to village rooms. Mountain huts and the katuns serve walkers doing multi-day routes.

July to September for walking, when the snow has cleared from the high routes and the katuns are occupied. December to March for skiing at Savin Kuk. May and June are green and empty but the highest paths may still hold snow.
