Postojna Cave
Admission included180 min
Postojna Cave, the queen of all caves, is the best-known cave in the world. It is also the greatest tourist attraction in Slovenia and one of the world’s largest karst monuments. This is the only place in the world where the underground landscape can be traversed on an electric train and where you get to meet this underground kingdom’s most famous inhabitant – the proteus (olm) – up close. A fantastic web of tunnels, passages, galleries and halls, astonishing diversity of karst features, as well as easy access are certainly the main reasons for such popularity of the cave and a large number of visitors (more than 36 million of them in over 200 years).
Predjama Castle
Admission included60 min
The Predjama Castle reigns over the surrounding area, not far from the Postojna Cave, in the idyllic village of Predjama. This picturesque, magnificent, defiant, mysterious and impregnable castle has been perched up in the middle of a vertical 123-meter high cliff for more than 800 years. Its romantic appeal is further emphasized by the idyllic Lokva River, which disappears into the underground world deep down below the castle. As the only preserved cave castle in Europe, the Predjama Castle offers a unique insight into the building techniques and resourcefulness of people in the Middle Ages, who were looking for and found a safe harbor for themselves right at the entrance into the cave. During a siege that took place in the 15th century, the castle provided a refuge for its best known and most notorious owner - Erazem of Predjama. The legend about the courageous robber baron Erazem, who remained undefeated until one of his servants betrayed him, is still in people’s minds, inspiring and alluring as ever. It was this safe abode of his which helped the brave knight resist the besiegers without much difficulty for more than a year.

Great day trip
We had such a great day on this tour with our guide Norman he was brilliant. He gave us lots of information on the drive over and was happy to answer any questions.
Once we arrived we went to the castle first which was really interesting learning about the history there and taking pictures :) I would recommend wearing trainers or boots as some of the climbs are a little steep/slippery inside.
We also had an audio guide provided which was great. Then we moved onto the caves where we had an unforgettable experience on the train to enter. I’m not a big ride person really and it’s so good for anyone/all ages as it’s such a fun activity. The caves were magnificent, there is so much to see. We spent about an hour walking around and then finished by looking at some of the salamanders that live there.
It was a great day trip!

Cave and castle!
We were on a cruise and wanted to see both the cave and inside the castle during our tour. The bus met us at the ship, and it was easy. The bus is nice, air conditioned and the guide, Vesna, kept us informed on the drive. The stop at the castle was great, and using your cell phone with their audio guide was helpful. Having your AirPods might make listening easier. We did feel a little rushed, and skipped over the last few stops in the castle to get back to the bus. Once on the bus, we waited 30 min while the guide looked for 2 passengers she thought were late. We left and made it to the cave, with around 45 min to eat or shop before our tour. We felt that was enough time, and wished we had more time at the castle. The cave tour was really excellent and they aren’t kidding that it is cold (50 F). We brought sweatshirts but wore shorts and were OK but you definitely need a jacket. The whole tour took 7 hours, and they did drop off a few people at the city center but otherwise drove us back to the ship. 4 stars only because we would have liked more time at the castle.

A must-see
We visited the caves on August 13th, but keep in mind that the temperature inside is constant all year round at 10 degrees. Dressed in long pants and equipped with a backpack containing sweatshirts and jackets, we headed to the entrance where a small train will take you, in about 10 minutes, inside the caves where the walk will begin, which will last approximately 1 hour before taking the train back. The caves are very beautiful with an easy and simple path even for children.

Go, you won't regret it
It was a great experience to take home. Absolutely recommended! The guide was incredibly polite and attentive to translating, both in English and Italian. He told many things that were both educational but also fun.

Great tour in lovely Slovenia!
We loved our guide, who is originally from Slovenia, and the driver! Great information en route, and very kind to me with limited mobility due to knee injury. Be aware of fast paced walking in cave, often uphill. Bring a jacket for cave, but chill air was so welcome in contrast to outdoor heat wave! Recommend this combined tour, especially because of our Guide!
