A 6-hour Ljubljana tour pairing Postojna Cave’s underground train and blind salamanders with Predjama Castle’s cliffside Renaissance drama.

“Our tour guide Ben was great and was very knowledgeable on the caves and castle. We took the afternoon tour with just 4 of us so felt like we had a private tour. Caves are magnificent and the castle is one of a kind built into a rock face. Self guiding audio tour of the castle was very well done.”
