Lake Bohinj is located in a glacial valley and it comprises almost 100 million cubic metres of water – according to an old Bohinj joke: no more than a bucket if it is large enough. The steeply descending lake basin is relatively smoothly shaped and has no shallow areas. In summer, the temperature of the water rises to 22 °C; in winter, the lake freezes sometimes. The water level rises 2 – 3 metres after heavy rainfall.
Lake water is restored 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.
Lake Bohinj is perfect for water activities all year round – from swimming, boat riding, windsurfing, kayaking or canoeing, fishing and diving in warmer months, to (sometimes) even ice skating in winter. Visitors can also take a wonderful tourist boat ride or simply go for a relaxing walk along the shore. If ice skating is an option, please be aware, that you can only skate and walk on the ice at your own responsibility. We recommend you to be extremely cautious!
