Postojna Caves & Predjama Castle

Today we take you to the biggest and most world-renowned Slovenian cave system – the Postojna caves.

This two-million-year old and 27-km-long system of subterranean caves is one of the most easily accessible networks of underground caves in the world. A ride by electric train will be followed by a guided walk through a series of cave halls with stalactites, pillars and translucent curtains that create unforgettable impressions.

The underground system is home to the mysterious, unique and rare amphibian Proteus Anguinus, or "human fish", as it is popularly known here.

Only nine kilometres away stands one of the most interesting Baroque castles in Slovenia, Predjama Castle. It appears to hang dramatically in the middle of a 123-metre-high rocky cliff.
