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.
