Black Lake, Montenegro: Crno jezero at Žabljak

What Black Lake is and where it sits

Crno jezero lies about 3 km from Žabljak, close enough to reach on foot, by bicycle or by car. The lake is actually two bodies of water, Veliko Jezero (Big Lake) and Malo Jezero (Little Lake), joined by a narrow strait that often dries up during summer. Despite its name, Malo Jezero is the deeper of the two, with a maximum depth of 49.1 m.

The lake sits inside the national park boundary, which shapes the practicalities of the visit: you pass through park entry rather than arriving at a free roadside attraction. Žabljak is the natural base, and the town's layout, facilities and access roads are worth reading before you drive north.

Why it suits non-hikers

You do not need to be a serious hiker to enjoy Black Lake. A relaxed walk around the shore gives forest, water and mountain views without technical planning, which makes it a sensible choice for mixed-ability groups and for travellers who want the mountains without a full day on foot.

Travellers with limited time in the north should put the lake ahead of ambitious objectives and treat bigger summits as a separate trip. If you want the wider picture of what the park holds, from the high peaks to the scenic drives, the Žabljak attractions hub pulls the individual guides together.

The lakeside path: length, time and surface after rain

A well-marked trail of roughly 3.5 km circles the lake, with views of the surrounding mountains and forests along the way. It is relatively easy and suits most fitness levels, taking about 1.5 to 2 hours to complete at an unhurried pace.

The surface is the one thing that can change the day. The trail becomes very muddy after rain, which makes sections harder to navigate than the distance suggests. Shoes with grip are the practical choice, and if it has rained heavily, allow more time or walk only part of the circuit before turning back.

If you want to see the shape of the path and how it relates to the roads and the town before you arrive, a map of the area makes the layout clearer than a written description.

Is swimming possible in summer?

Swimming is a summer activity at Black Lake, not something to count on outside the warm months. The lake is described as suitable for swimming in the summer season, so treat it as a seasonal extra rather than the reason for the trip.

Mountain water stays cold even on hot days, and the weather at this altitude is not the same as on the coast. Bring a towel only if you genuinely intend to get in, and keep the walk itself as the main plan.

Boats on the water

Row boats are available for hire in summer, which gives a different view of the lake and the mountain walls around it. Hire is a summer service, so do not build a day around it in the colder months.

If a boat on the water matters to you, ask in Žabljak when you arrive rather than assuming it will be running on a given date, and keep the lakeside path as the fallback.

Getting there from Žabljak and where parking is

The lake is about 3 km from Žabljak and can be reached by car, by bicycle or on a pleasant walk from town. The walk in is short and, for anyone staying in Žabljak, removes the need to move the car at all.

In high season, arrive early for easier parking and quieter paths. The difference between an early start and a late one is mostly about how much of the walk you do alone, and staying in Žabljak means you can leave the car behind and walk in.

Do you need to book ahead?

There is an entrance fee of €5 for entering Durmitor National Park, which includes access to Black Lake. Treat that figure as the published rate rather than a guaranteed price on the day, and check the current charge when you arrive.

Advance booking is not required for the lake itself, which makes it a flexible option when mountain weather is unstable. The lake can still be visited in a shorter window, so it suits a day when plans have already shifted.

Best time of day for light and crowds

The site gets crowded during the day, especially when tourist buses arrive, though walking further around the shore tends to leave the crowds behind. The middle of the day is the least rewarding window if you want quiet.

A late afternoon or early evening visit is recommended to avoid the crowds and enjoy a quieter experience. For photography, morning and late afternoon give better light than harsh midday sun.

That leaves a simple choice: an early start for parking and calm water, or a later arrival for softer light and fewer people. Either works; a midday arrival in high season gives you neither.

What to wear and carry at altitude

Mountain weather can change quickly in Durmitor, and colder evenings occur even in summer. Carry layers, water and shoes with grip even if the coast is hot, because the temperature at the lake is not the temperature in Kotor or Budva.

The essentials are modest but specific: footwear that copes with mud, a waterproof layer, and enough water for a couple of hours on the move. Camera gear is worth the weight here, and the path is short enough that you are not carrying it far.

Combining it with the rest of Durmitor

One full day is the minimum for the park, and two nights are better if you want the lake, viewpoints and Tara Canyon without rushing. A short visit can pair Black Lake with a simple viewpoint rather than a demanding route.

If conditions are good, Curevac viewpoint is a strong Tara Canyon option, and the Durmitor Ring Road is excellent for a scenic drive that deserves time rather than a rushed detour. If you would rather have the driving and activities arranged for you, there are local tours from Žabljak.

The drive north is long if you are coming from the coast, and that shapes how much you can fit in. Build the day around the lake and one other stop rather than trying to tick off the whole park, and use the guide to the town itself to sort out fuel, food and an early start.

Is the lakeside circuit worth it on a short northern trip?

Yes, if you are already heading to Žabljak. The 3.5 km circuit is manageable for most people, gives you the mountain scenery that makes the north feel different from the coast, and takes less than half a day. It is the lowest-risk way to spend time in the park when the weather is unsettled.

Go early for parking or late for light and quiet, wear shoes that handle mud, and keep one other stop for the afternoon rather than a full schedule. The entrance fee is paid for the national park as a whole, so the cost covers the wider visit rather than just the lake.
