Perfect 1/2 Day - We were excited to see Predjama Castle and the Postonja Cafes but we didn’t want to take up our entire day doing so. This was perfect. 8:20 pick up and 2pm drop off. Jan was an excellent guide and made everything seamless.

Great half day adventure... - Great half day adventure with an astonishing cave and an equally impressive castle IN a cave. Nina both drove and lead the group with aplomb. It's a great way to get out of the city and see some things (for me at least) not easily seen at home.

Postojna Cave & Predjama Castle … a great experience - A fantastic day at the Postojna caves and Prediama Castle. The minibus was very comfortable and our guide, Thea, was extremely professional, knowledgeable and a lovely person. The tour was great value and a great use of our precious time in Slovenia. I would recommend this tour to all.

Nice visit - It is a very interesting cave, the largest in Europe. Part of the visit is carried out with a train, followed by a pleasant walk. Beautiful rooms, the magnificence of nature. In the surroundings you can make a pleasant stop to eat.
