On this day we take you to the biggest and worldwide known Slovenian cave system - the Postojna caves. Amazing two million years old and 21 km long system of underground caves is one of the most easily accessible networks of underground caves in the world. First, you will experience the ride by electric train, after that, a guided walk will follow through a series of cave halls with drop stones, pillars, and translucent curtains that create unforgettable impressions. The underworld system is home to the mysterious, unique, and rare amphibian Proteus Anguinus, or “baby dragon” as it is popularly called here. Back in the daylight, the trip will continue towards the astonishing castle of the robber knight Erasmus. 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. Driving through the green scenery, we return to Ljubljana.
