Guided half-day tour from Ljubljana to Postojna Cave and Predjama Castle, with pickup, underground train, skip-the-line entry, and audio.

“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.”

Ride the electric train through Postojna Cave and visit Predjama Castle, guided from Ljubljana with skip-the-line tickets.

“We were originally booked on the morning tour but were asked to move to the afternoon tour due to numbers so it was just lucky that we could change our plans. The traffic was bad and our guide, Bor, picked us up at 2:30pm. The office did message us to say traffic was bad and pick up would be at 2:10pm. Bor provided a great history lesson on Slovenia as we drove to the castle. The castle and caves were brilliant and we are certainly glad we did the tour but it felt very rushed due to 30 minute difference between stated pick up time and actual pick up time.”

“Our second of two tours with Matej. We chose to split this tour and the Lake Bled tour into two days over the full day option and loved both tours. Matej was a great tour guide and not only provided us with Slovenian history and background of the destinations, but some insight into Slovenian politics and changes since the Yugoslavian era. Postojna caves are incredible and the train ride within the caves is a neat experience within itself. Predjama castle is really unique and fun to explore.”
