Postojna Caves

Sonali Shah
Postojna Cave is a 5.2 Km long karst cave system created by the Pivka River. The caves are home to the endemic olm, the largest trogloditic amphibian in the world. A mini - train (open air) takes you through the deepest end of the cave to see the Stalagmites and stalactites.
