The tour has been great! We have seen very interesting and beautiful places. The guide Vladimir has been great as well. He has told historic issues with a good sense of humour, which has been quite interesting and fun. Thank you! Highly recommend.

Our guided tour of Postojna Caves and Predjama Castle was fantastic. Our guide Vladimyr promptly picked us up from our hotel in Ljubljana and immediately made us feel welcome in Slovenia by sharing a bit about himself and why he chooses to lead these tours. He ensured we got the most of our tour and was incredibly knowledgeable about the Caves, Castle, and Slovenia in general. We had a great time and highly recommend visiting this tour for ease, learning, and fun.

amazing castle and views

Fascinating places. I've never visited such long spectacular caves before and what a good idea to have an open air train running through them. Take a warm jacket though because the temperature in there is 10 degrees (all year around). I loved Predjama Castle too, made even more interesting by our legendary and entertaining guide, Vladimir.

Lana, our guide, was fabulous. Full of information about the caves, the castle, and Slovenia in general.

Predjama Castle is such a delight. It is one castle that really is just like the travel brochure photos you see of it. When you first see it and the way it is positioned inside the cave, it looks like so ething out of a hollywood movie set. But it is very real, and a total step back in time as you walk through it.

The Postojna Caves are incredible. There are no words to adequately reflect their size and beauty. A visit to these caves is an absolute must when you visit Slovenia. They will leave you in awe of mother nature and the beauty she can create.
