Is the largest natural lake in Slovenia. Nested in the heart of the Julian Alps, this jewel is a precious natural resource and at the same time offers endless opportunities for outdoor activities. Lake Bohinj is located in a glacial valley and it comprises almost 100 million cubic meters 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 often freezes. Water level rises 2 - 3 meters after heavy rainfall.
