Durmitor National Park above Žabljak has 25 marked trails over about 150 km, 48 peaks above 2,000 m and 18 glacial lakes. The easiest walk is the loop around Black Lake, 3.6 km in about an hour; the classic viewpoint climbs are Savin kuk and Ćurevac. The hiking season on the high massif runs from June to the end of October.

Trails with official lengths and times
| Trail | Length | Time | Grade |

| Black Lake educational loop | about 3.6 km | 1 h | easy |

The first three are from the park's own list; Savin kuk and Ćurevac figures are from the Žabljak tourist office trail pages. Grades follow the national three-step scale (easy, medium, hard) that the mountain trails law requires on maps, boards and guides. Both climbs have their own pages: Savin kuk and Ćurevac viewpoint pages.

The NTO's Durmitor page gives the trail network as 100 km; the park's own activity page says about 150 km.

- Škrka hut: open mid-June to late September.
- Sušica hut: open late June to late September.

When to go
The NTO gives June to the end of October for the high massifs and names July to September as the best months for Durmitor. The two staffed huts follow roughly the same window. Black Lake at 1,418 m is reachable for longer than the ridges.
