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.”

★★★★★★★★★★4.6 · 576 reviews · 2 hours · from $23

A 2-hour guided walk plus a funicular ride to Ljubljana Castle, with major sights, local stories, and unbeatable city views.

“Walking tour that gave us some history but lots of insights into Slovenian life. Andre was an entertaining and engaged guide, and made the two hours fly. Would highly recommend the tour to give you a good grounding on the city’s history. One tip: the group was too big to fit in one funicular, and the few left behind missed the last bit of the tour, which talked about the castle (we think!)”
