Air conditioned, comfortable ride to the caves. Jan was a great tour guide and answered all our questions as we drove there - he was very knowledgable about Slovenian culture and politics. The caves are a MUST-see! Truly breath-taking. Be prepared for an hour-long walk and cold temperatures. The Predjama Castle is also very cool. Jan's guidance through it was preferable to an audio-tour. And on the ride back he entertained all of my 10 year old son's questions while the rest of us comfortably napped! Thank you, Jan! One thing to note: Entrance ticket into the cave and castle are NOT included in the price of the tour. Be prepared to have your guide help you purchase that ticket with cash or credit.

We had a great day with Nina. The pickup was on time and the van was comfortable and the air conditioning was great. The first stop was Predjama castle which was unlike anything I had seen before and not sure how they built that structure in to the mountain. The caves were also great. I haven’t explored caves before so I can’t really compare but the structures inside were fantastic. Definitely bring a sweater or a light jacket. It was extremely hot the day we visited but was was freezing with a sweater by the time we left. Nina was a great guide and driver and was waiting for us nearby when we left each attraction. I highly recommend this tour.

Great experience, it was easy to work with the company, guide was on time, lively, and fun. Cave was unique and infrastructure excellent. Castle was very i on the outside and Urban’s lively narrative made the experience all the better. Best of all, no issues whatsoever so you can engage and enjoy the experience.
