Black Lake Žabljak, or Crno Jezero, is the easiest place to begin exploring Durmitor National Park. It is close to Žabljak, the main path around the lake is 3.5 kilometres long, and the view towards Međed gives you the mountain scenery without committing to a full-day hike.
That accessibility is also why the entrance can feel busy in summer. A little planning makes a noticeable difference: arrive earlier, allow more time than the distance suggests, and treat the lakeside circuit as a walk rather than a race.

What is Black Lake?
Black Lake is the largest lake in Durmitor National Park. Despite the singular name, it has two connected parts: Big Lake and Small Lake. In summer, the water level can fall enough for the natural connection between them to disappear temporarily.
The name does not describe dirty or black water. It comes from the dense conifer forest reflected on the surface. Behind the lake rises Međed, one of the defining shapes in the Durmitor landscape.
Durmitor National Park is part of a UNESCO World Heritage property shaped by glaciers, rivers and underground water. Black Lake itself has a long protection history: UNESCO records that it received protected status in 1907, decades before the national park was established.
How to reach Black Lake from Žabljak
The official tourism information places the lake three kilometres southwest of town. You can reach the main entrance by road or walk from central Žabljak. Driving is convenient if you are travelling with small children, carrying extra clothing or continuing elsewhere afterwards. Walking avoids the parking fee and works well if the weather is settled.
Do not use the walking distance as a reason to leave your rain layer behind. Žabljak sits at about 1,450 metres and conditions can change quickly. Our Žabljak packing guide covers the useful basics for every season.
Walking around Black Lake
The full circuit is 3.5 kilometres. It is an approachable lake walk, but not a paved urban promenade. Expect natural surfaces, roots, uneven sections and conditions that change after rain or snow. Comfortable shoes with grip are a better choice than smooth city footwear.
If you only want the classic view, you do not need to complete the loop. The area close to the main entrance gives you the lake, forest and mountain backdrop with very little walking. The full circuit is worth doing when conditions are good because the view and character change as you move away from the busier entrance side.
Allow at least 90 minutes for an unhurried loop, more if you plan to stop for photographs or spend time by the water. This is a planning allowance rather than an official walking time. Families with young children should keep the day flexible and turn back if the surface becomes uncomfortable.
When should you visit?
Late spring through early autumn gives the simplest walking conditions, but the exact date matters less than current weather and snow. July and August offer long days and the busiest entrance. June and September often make a better compromise for visitors who want to walk without peak-season pressure.
Autumn colour can be excellent, while shorter daylight and colder mornings deserve respect. In winter, the frozen lake and snow-covered forest create a completely different visit. Stay on safe, obvious routes, follow local signs and do not assume that a summer path will be equally simple under snow or ice.

Tickets, parking and boat rental
The €5 daily ticket includes access to the Visitor Centre and educational trails. National Parks of Montenegro also sells Durmitor tickets online, and children under 15 are exempt from the entrance charge. If you arrive by car, the current passenger-car parking fee is €1 per hour.
Boat rental is listed at €10 per hour. Treat availability as a same-day question rather than a promise: weather, season and operating conditions can affect services. If a boat matters to your visit, confirm it with park staff when you arrive.
Is Black Lake suitable for children?
Yes, if you match the plan to the child rather than insisting on the full loop. The entrance area is the simplest option, and the circuit can be shortened at any point by turning back. Bring water, a snack, an extra layer and shoes that cope with a natural path.
A pushchair should not be assumed to work around the entire circuit. Trail surfaces and weather can make sections awkward. Families who need a predictable, barrier-free route should ask the Visitor Centre about current access before setting out. More realistic family ideas are in our Žabljak with kids guide.
Can you continue to other walks?
Black Lake is a starting point for several marked routes, including connections towards Barno Lake and Zminje Lake, as well as much more demanding mountain objectives. Do not mistake a busy lakeside entrance for proof that every route beyond it is easy. Distance, elevation, exposure, remaining snow and daylight all matter.
Choose a route based on current conditions and your actual experience. Our verified walks and hikes around Žabljak separates simple outings from serious mountain days.
A short safety checklist
- Check the forecast and daylight before leaving.
- Wear footwear suitable for a natural path.
- Carry water and a warm or waterproof layer.
- Follow signs and any instructions from park staff.
- Do not continue onto a longer mountain route without enough time and equipment.
- For an emergency in Montenegro, call 112.
The Mountain Rescue Service of Montenegro advises callers to stay calm, protect the injured person and themselves from immediate danger, give first aid within their ability, mark the accident location and provide precise information to rescuers.
Where Black Lake fits in a Žabljak stay
Black Lake works well on an arrival afternoon, as an easier day between two longer outings, or as the main activity when the weather rules out exposed trails. It is also a useful first stop because it shows what makes Durmitor distinctive without using all your energy on day one.
Villa Eagle gives up to six guests a private three-bedroom base with a fully equipped kitchen, living area, Wi-Fi and on-site parking. See the house and facilities, then check current availability on Booking.com or Airbnb.
