Lake Bohinj is the largest natural lake in Slovenia. Nested in the heart of the Julian Alps, this hidden gem is a precious destination waiting to be discovered!
Lake Bohinj lies deep in glacial valley guarded by steep slopes on all but one side with green pastries. It holds about 100 million cubic metres of water - and as the old Bohinj saying goes: it holds no more water than a bucket - if it is large enough. It is part of the Triglav National Park, the only National Park in Slovenia and its pristine charm will get you in love at first sight. In summer, the temperature of the water rises up to 22 °C; in cold winters, the lake often freezes. Water level rises 2 - 3 metres after heavy rainfall.
LAKE BOHINJ IN NUMBERS
- Surface elevation: 526 m
- Length: 4100 m (the longest diagonal)
- Maximum width: 1200 m
- Water quantity: 92.5 million m3
- Maximum depth: 45 m
- Area: 318 ha
- Shore length: about 11.35 km
Water is completely refreshed three times per year. The main tributary is the Savica, and the main distributary is the Sava Bohinjka. More than a third of the water flows into the lake from the Karst springs under the lake surface along the northern shore. During heavy rainfall, the Karst waters gush out as the Govic spring on the Pršivec hillside.
