Divje Jezero is a huge deep blue karst spring, the emergence of the
Jezernica river, which flows after only 50m into the Idijca river.
The spring is a collapse doline, the end of a cave system which drains the
mountains to the south.
The cave below the lake goes down vrather steep.
It is until today explored for 160m, going down 83m deep.
The big depth is an enormous problem for human divers and so exploration has
come to an end.
The cave was formed along a tectonic fault, which is visible in the rock face
behind the spring.
But this is not only a geologic site.
The flora and fauna around the spring is exceptional and protected.
There are also Olms (Proteus anguinus) living in the cave, which are
sometimes transported out by floods.
At normal times the fresh water is full of trout.
The lake is a famous tourist destination, although it is off the major tourist
