    Lake Plav between green mountains, with red-roofed houses on the shore and clouds over the valley

    Plav, northern Montenegro

    Lake Plav, the big glacial lake below the Prokletije

    Lake Plav lies at 906 metres beside the town of Plav, covering 1.99 km² with a maximum depth of 9.1 metres according to MONSTAT. The local tourist board calls it Montenegro's largest glacial lake. It's fed by the Ljuča, carrying Prokletije snowmelt, serves as the town's beach in summer and freezes in winter.

    • Lake Plav covers 1.99 km² at 906 metres and is 9.1 metres deep at most.
    • Plav Tourist Board calls it Montenegro's largest glacial lake.
    • In summer there's a swimming platform, boat hire and lifeguards.
    • It freezes in winter and is the starting line for the Lim Regatta and the Plav Triathlon.

    Lake Plav isn't a high-mountain lake for postcard shots, it's a lake to spend time at. I'd save it for the afternoon after a Prokletije hike and cool off from the floating platform. In winter, however solid it looks, I wouldn't walk on it.

    Before you go

    What I would keep in mind

    1. 01 Most beautiful

      The country's largest glacial lake

      That's how Plav Tourist Board describes it. MONSTAT gives it 1.99 km², well ahead of other mountain lakes such as Durmitor's Black Lake, at 0.52 km².

    2. 02 My tip

      Lifeguards in summer

      The tourist board hires lifeguards for the lake in season, and the floating platform doubles as a swimming area and a place to hire pedalos, kayaks or rowing boats.

    3. 03 Worth the splurge

      Triathlon and regatta

      The Lim Regatta left the lake on 29 May 2026 for its 134 km run to Prijepolje, and the swim leg of the 2nd Plav Triathlon was held here on 15 August.

    4. 04 Getting there

      On to Lake Hrid and Ropojana

      The national tourist board suggests an easy lakeside walk, and from Plav routes lead up to Lake Hrid, at 1,970 metres, and to the Ropojana valley beside Vusanje.

    What I would book

    Lake Plav is the reason the town exists and the place everyone who spends a few days in the Prokletije ends up coming back to. MONSTAT gives it 1.99 km², an altitude of 906 metres and a maximum depth of 9.1 metres. Plav Tourist Board claims no glacial lake in Montenegro is bigger, and although I haven’t found another official source making that comparison, MONSTAT’s figures put it well ahead of the glacial lakes of Durmitor or Biogradska Gora.

    A lake born in the Prokletije

    The tourist board explains that ice and snow hang on in the Prokletije until June, and the meltwater feeds the streams that form the Ljuča, the river flowing into the lake. Its own figures differ slightly from MONSTAT’s, 907 metres, 2 km², an average depth of 3 metres and 9 at its deepest, but they broadly agree. The national tourist board places the town of Plav between the lake shore and the source of the Lim, the river that runs the length of the valley past Andrijevica and Berane.

    What strikes me is the scale. It’s a flat, shallow lake fringed with meadows and houses, with Visitor and the Prokletije all around, which makes it somewhere to be rather than just something to look at.

    Swimming, paddling and fishing

    In summer the water gets warm enough to swim, says the tourist board, and a floating platform serves as the bathing area and the place to hire pedalos, kayaks and rowing boats. The tourist office hires lifeguards in season, which makes it the best spot in the area for a swim with children.

    Fishing is the other big draw. The board lists Black Sea trout, glavatica trout, grayling, zander, chub and barbel in the lake and calls it a paradise for fly fishing. You’ll need a licence, as everywhere in Montenegro.

    The lake in winter

    The tourist board says the surface freezes in winter, to the point that you can walk on it. I mention it because it’s part of the lake’s life, but I wouldn’t recommend it, since no official source publishes ice thickness or safety warnings. In winter, the snowy Prokletije and the frozen lake seen from the shore are reason enough to come.

    Events and walks from the shore

    The lake is also a stage. On 29 May 2026 the 27th International Lim Regatta set off from here on its 134 km run to Prijepolje, and on 15 August the 2nd Plav Triathlon was held. From the shore, the national tourist board suggests easy walks, and Plav is the starting point for the high lakes of the Prokletije, such as Lake Hrid, at 1,970 metres, and Lake Abdija, at 2,054, which the board calls the highest in the country. On the far side of the valley, the road continues to Gusinje and the Ropojana valley beside Vusanje.
