Great way to spend a day in Ljubljana! - We signed up for a small group tour, but it turned out we were the only ones on the tour that day. We got our fabulous guide all to ourselves for the Predjama Cave/Castle; he was very knowledgeable and fun to be with. Afterwards the Postojna Cave visit was extremely well-organized and fabulous to see; even though they take thousands through the cave every day, we only saw part of one other group during our tour. Our Roundabout guide was timely both when he picked us up in the morning and upon completion of the Postojna Cave tour. Altogether a fabulous tour and a great way to spend a hot and humid day in Ljubljana!

def do the tour! - there were only four of us on the tour which was great, i was able to sit in the front seat as i get car sick easily which i appreciated, pick up and drop off was great, the whole tour was very punctual, he gave us a personal tour of the castle and made sure we were in the right spot for the cave tour, we were so happy we did the small group tour vs driving ourselves, def recommend

Great trip - Very enjoyable trip. We were picked up on time by our lovely guide. There were only 4 on our trip and we were made very welcome. She gave us lots of information. The castle visit was good but be aware that there are lots of steps. The Cave trip was good. Enjoyed the train ride and the Cave was very interesting

Amazing - What a wonderful day we had. Both the cave and the castle were incredible & must not be missed. Our driver Faris was a great source of information, professional, friendly & an all round great guy. Thanks Faris.

Great tour over all… would do it again - It was an amazing trip to an incredibly Beautiful location… I thought it was a little expensive .. and still didn’t cover the entrance fees … but the tour guide was very informative and very helpful… she gave very good recommendations as to what was worth doing and not. The cave especially, was a major attraction … HIGHLY RECOMMEND.. the Postojna castle was just ok… nice castle from the outside, but not worth the cost to go inside Lake Bled Castle was worth the cost just for the view alone … I would definitely recommend this tour overall

Highly recommended trip - Excellent and comfortable trip to postojna cave and the castle.. our tour guide Tajsa showed up in time.. she is well educated and alot of information to tell us .also she is a good driver... everything went perfectly and easy..Tajsa bought for us the tickets to avoid the waiting lines... we had plenty of time inside the stunning cave (2 hours) .. then 1 hour to visit the castle which was amazing .. thank you for the great trip..highly recommended

Very good experienced guide, but not much free time at the sites. - Our guide Primus was really experienced and it comes across in how much he was able to share about Slovenia at the beginning of the tour. He took our group of 4 to the Castle first to avoid crowds at the Cave and personally guided us through it, instead of us using audio guides. We had about an hour here. Then we were driven to Postojna Cave, shown where to line up for an official English tour, and told to meet after in the carpark by 1pm. The wait wasn't too long. Towards the end of the tour (after seeing the "Baby Dragons"), there's a World's Only Cave Post Office so don't dawdle too much or you won't have enough time to shop before the return train leaves. We had about 20min after the tour to browse the outside shops and use the toilet. The 1pm deadline was pretty strict as our guide didn't want to be caught up in traffic back to Ljubljana. This didn't feel like it was enough time. So the tour did the job to get us to the sites, but there's hardly any leisure time.

A nice excursion! - Postojna Cave is a must, even if there are really many tourists! The groups are very large, and it is not always easy to understand the guide! That said, the experience is definitely worth it! In Predjama Castle, there are fewer people. However, there are many steps!

Good trip - The trip from Ljubljana city centre to Predjama Castle and Postojna Caves was very good. We started on time (8:30 am) from the city centre on a good van with air conditioning and an English speaking driver. There were only three people (me included) in the tour, so it was a kind of a "private" tour. The driver explained some basic facts about the caves, the castle and the history of Slovenia. After arriving at Predjama Castle and having bought the ticket (valid for both attractions) we visited the castle (nice, although most of it was reconstructed after WW II), and we had about half-hour free time before driving to Postojna Cave. The caves are spectacular, and the visit starts with a subterranean train ride for approx. 3 Kilometers. Then there is a 1.5 Kilometers walk through several cave chambers, and at the end another train ride that brings you back to the cave entrance. At the castle we were provided with an audio guide (far too detailed), and at the cave the tour was explained by a guide belonging to the Caves organization - these explanations were somehow very basic.

Overpriced Shuttle Service - This is basically a private shuttle that takes you to the entrance of both sites. The price is actually closer to $110 total as it does not include the entrance to either site. Our tour guide didn’t talk on the ride, and he dropped us off at the castle to explore on our own inside of guiding us through. So I’m not sure why this was labeled as having a tour guide. If this was half the price I’d say it’s worth it but the cost is too much for what you get.
