Cracking combination of castles and caves - David was an excellent guide and very knowledgeable and friendly. He answered all our questions and was an excellent driver / host. The caves are stunning and the castle fascinating. A highlight of our visit to this wonderful country.

Great Fun Cave and Cave Castle Experience! - Very good experience. Our driver and guide (Nate) was very knowledgeable and funny. He talked us through the fun facts in his own entertaining way throughout the ride to the venue. He also engaged small talk with us which was very much appreciated. The Castle built on the Cave was very special. You need to see it for yourself! The Cave inside is breathtaking, I couldn't stop spamming photos inside. To enter, I also sat a roller coster style train inside to the main chambers which was very cool. The English guide spoke clearly, sharing interesting information. Lastly, the tickets to the Cave and Castle were well discounted for myself as a student. 100% would recommend!

Amazing day - Amazing trip. The castle and then the caves. Due to foggy weather conditions in Ljubljana i thought that it wouldn't be worth going. Out further the weather changed we were able to see the scenery, then onto the castle where we walked round. From there onto the caves. This was all made very spectacular by our super guide Nate. He was very informative. Telling us the history and the dates of what had occurred in the past. I would highly recommend it.

Great castle and cave trip from Ljubljana - Did the Postojna Cave and Predjama Castle tour today from 1.15 to 6.30pm. Picked up on time by David on an eight person van tour. David was very professional, courteous and quite knowledgeable on all things associated with the tour and Slovenia in general. The cave system is something hard to put into mere words, particularly as it’s the third largest in the world. Not to be missed. Thanks David.

Postojna Cave and Predjama Castle Tour with Slovenian Wander - What a fantastic experience my family and I had with the Slovenian Wander tour company on 03 September 2025 to Postojna Cave and Predjama Castle. David the driver and guide was brilliant. He was extremely friendly, helpful and knowledgeable which made the afternoon really enjoyable and overall a great afternoon with minimal stress. Can’t recommend David and the organisation enough. Thank you all, a 5 star experience.

This tour was not... - This tour was not completely what I expected. Our driver, David, was very knowledgeable and imparted some great information about Slovenia and the region we were headed to. But I didn't realize he was not our tour guide for the two places we visited. For the Predjama castle we were given audio guides which I tend to not use (preferring having an actual guide with me), but which did impart some interesting tidbits about the various rooms & items within the castle. And while I do like having an in person guide, having an audio guide instead did give us the freedom to spend as much or as little time in each section of the castle as we wanted, take time for various photo ops, etc. For the Postojna caves, we did have a guide. But again I didn't realize it wasn't going to be David but rather a guide there, where they take in massive groups at a time so our small group of 8 was thrown in with another 50-60 people which made the tour itself a bit less enjoyable. The tour also has us walking through various sections of the cavern very quickly with very little time for photo opportunities and my husband and I fell behind from constantly stopping to take pictures and ended up missing some information on a few of the sections we walked through as the guide was not stopping and waiting very long before moving along. Despite this I think the tour was still highly enjoyable overall. If there was a way to have a smaller group in the caves I think that would be great, but it doesn't look like that's how they have it set-up so I don't know that that is possible. Would still recommend this tour. I fully expected the caves to be the highlight of the tour for me but it ended up being the castle which had some interesting history and was quite a lot of fun to walk through and visit.
