Blidinjsko Lake is the largest mountain lake in Bosnia and Herzegovina. It is located at 1185 meters above sea level.The lake is long, about 2.5 kilometers wide, about 2.1 kilometers, a maximum depth of the lake, yet in some places, is about 3 meters. Otherwise, the lake is very shallow, average depth is about half a meter.

The melting glaciers from Čvrsnica during the two past ice ages created this open and barren valley Dugo Polje field leading into the park.

Blidinje lake is the direct result of a glacial retreat, but according to the Poklečani Parishes office documents, lake is, also, a product of anthropogenic intervention and activities of human inhabitants. According to these documents, in order to keep the water that is lost through the subterranean passage, local residents and cattle breeders were sealed sinkholes with branches and clay, so that water could not find its way underground. Therefore, the lake was formed.

Lake is located in the Nature Park Blidinje, so visiting this marvelous area in Herzegovinia will be something you will remember.
