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.

This is what I want from a tour company! - 1. Punctual. 2. Clean, comfortable vehicle. 3. Guide Izidor a good, safe driver. That mattered to us. 4. Guide Izidor knowledgeable, fit his Slovenia presentation to group level of interest. 5. Guide Izidor also personable. Felt we got acquainted with an interesting Slovenian. 6. Price seemed fair.

Excellent tour company and great destinations! - We liked this tour company (Slovenia-Explorer) so much that we did two tours with them. First, Predjama Castle plus Postojna Caverns (one tour) and, second, a tour to Lake Bled (including the castle). They do offer a tour that would hit all three destinations in one day, but that would make for a rather long day. On both tours, the destinations were great. The caverns were probably our favorite, because they were a bit more unique. The drivers on both days were fantastic (we particularly remember Jan, who had the advantage of having studied history in college) and we got a great mix of local color, ancient history, history from the Yugoslavia era to the present, and humor. The vans were clean and modern and the communication was clear and timely, which made everything simple and easy. The drives are also not too long—about 45 minutes each way. Great tours and a great tour company!

Great day trip from Ljubljana - This far exceeded our expectations. Although this wasn't a private tour, this van was comfortable and our guide was knowledgeable and personable. It seemed like a private tour and we made quick friends of the other people. The cave and particularly the train was much more fun and impressive than I would have imagined. The castle was also really unique given the setting into the mountain. I would highly recommend this tour.
