Visit the mesmerizing Postojna cave and find out about its history. It has taken millions of years for the clear waters of the River Pivka to create these 21 kilometers of underground labyrinth passages, caverns, and great halls, decorated with dripstones, translucent curtains, and pillars of fascinating shapes and colors. After an unforgettable underground train ride to the heart of the cave system, experienced guides will accompany you on a walk through the subtly lit fairy-tale-like underground world.
Back in the daylight, the trip will continue towards the astonishing castle of the robber knight Erasmus - the mysterious castle of Predjama. For centuries dramatically hanging in over a 100-meter-high vertical cliff, it's waiting for you to enter and discover its secrets, legends, and myths.
