Amazingly large cave and castle built into the cave.

Don_B, Jun 2026

This trip was fantastic. I knew the cave had to be large since it had a train but the cave is cavernous and miles long. I thought the train would be touristy and kind of a gimmick but it was not. It was necessary transportation to take you deeper into the cave. You get off the train in a large cave section and continue walking after that. We also did the castle and that was really interesting. It is built at the front of one of the cave sections. I’ve never been in a castle built into a cave before. Very enjoyable trip. The tour operator provided us a private driver and Sandra was great. Highly recommend.

Cave and Castle tour

Russ_R, Jun 2026

This was a great trip and well worth, the adventure. Two things to note are one. The temperature inside the cave is about 50° so bring a jacket this tour does not include admission fee to the castle.

Response from Host, Jun 2026

Thank you! Always welcome.

Tour not to be missed

Lorna_G, May 2026

Ernest, our driver, was early to pick us up. Very professional and knowledgeable driver. His English was very good and we enjoyed all the history and stories he told us along the way. He picked us up at the cruise terminal port. It was approx 40 min drive to the caves. We had time for a drink and bathroom break before going in the cave. There is a train that takes you around then there is approx 1 kil of walking some steep inclines (not slippery though). Then the train ride back to the beginning. The caves are impressive and worth doing. Ernest met us right after the cave tour and drove us to the castle. We had the option if we wished to have lunch at the caves or at the castle. I am so glad we chose the castle. We did the castle tour where they give you a portable tour device. You scan when you go into each room of the castle and it tells you a story about the room. After the castle we had lunch at the bottom restaurant (2 only) and what a view of the castle! Lunch was very good. I highly recommend the tour and hopefully if you do the tour you are luck enough to get Ernest as your driver for the day.

Fascinating Postojna Caves

The Postojna Caves and Predjama Castle is definitely worth a visit. Our guide, Matias was passionate about her job and knowledge. Shw met us at our hotel in Trieste and made our visit to Slovenia easy and worry-free. Thank you!

Great day with professional friendly tour guide

Stephen_D, Jul 2019

I can highly recommend this tour. From the moment we booked it, we had contact with Peter. We met him at the port and he introduced us to his driver. Comfortable transport, very friendly and knowledgeable driver/guide. We had a great day. This is a must do tour and a great tour company to use.
