On this day we take you to the biggest and worldwide known Slovenian cave system - the Postojna caves. A two million years old and 21 km long system of subterranean caves is one of the most easily accessible network of underground caves in the world. A ride by electrical train will be followed by a guided walk through a series of cave halls with drop stones, pillars and translucent curtains that create unforgettable impressions. The underworld system is a home of the mysterious, unique and rare amphibian Proteus Anguinus, or human fish as it is popularly called here.
Only 9 km away stands one of the most interesting baroque castles of Slovenia, the Predjama castle. It hangs dramatically in the middle of 123 m high rocky cliff.

Both sights are must sees for different reasons perhaps but worth the visit.

We loved this tour. Postojna Cave is beautiful and easy to go thru especially with young children. Predjama Castle is special, very different than other castle we have seen of course and our guide was very knowledgable.
