Postojna Caves Overview

The Postojna Cave takes pride in being one of the most sought after caves and tourist attractions in Europe. This is a series of cave systems stretching as much as 24 kilometres and is more than 2 million years old.

It was carved out by the Pivka river and also comes with an electric train that takes its visitors into the deep labyrinth network of tunnels. Visitors can explore up to 5 kilometres of the cave using a guided tour that takes you through tunnels and caverns. As you explore, you can catch a glimpse of the halls and galleries of the tunnel and know more about the network through audio guides.

The cave system is nicknamed as the Queen of the Underground World and also connects you to a fairytale world filled with knights and castles. Either way, the visit to the caves will be nothing less than an adventure, leaving you with awe and wonder.
