Lake Cerknica, the disappearing lake


An interesting lake of the Notranjsko-kraška is the Lake Cerknica, also known as the “disappearing lake”. The lake doesn’t actually disappear, although it does give that impression. In fact, Lake Cerknica is an intermittent lake, the biggest of its kind in Slovenia.


The many reservoirs and subterranean channels surrounding Lake Cerknica create a migration of water that changes the volume of the lake. During heavy rains, the water from the surrounding channels erupts and flows into the lake, flooding Lake Cerknica into the biggest lake of Slovenia. During the dry season, the reverse happens. Depending on the amount of water, the landscape of Lake Cerknica alternates from a beautiful gorgeous lake to wetlands to completely dry land. Sometimes, you might not even see that it is a lake.


This special feature of Lake Cerknica makes every visit a different adventure. When there is a good amount of water, you can do some water sports and if there’s none, you can take a walk at the bottom of the lake.


Every season is a good time to visit the disappearing lake of Cerknica.
