- Postojna Cave - 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 - 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.

WOW Experience - Absolutely great adventure. So many different structures to look at . This is a fairly aggressive walk so make sure you have comfortable shoes and a light jacket. It’s chilly in the cave (55 F).

Spectacular Cave Experience - The cave network is immense and we get to see only a fraction of it, but what we do see in an overwhelming display of massive structures.
There are other caves, but this is truly spectacular and truly worth a visit.

Castle and Cave is a WOW! - Amazing day. Interesting Castle and absolutely incredible cave. I have been in many caves but this was the best. I have never seen anything like these. Well organized with a train going back 2 miles. Then you walk through the caves for about 1 hour. Lots of uphill and down hill walking. Great tour. Great driver, Ernest did a good job of telling us about the country and many fun facts. Thank you

They take you to the... - They take you to the places and buy you the ticket, it is something that if you have a car you could do on your own, anyway, they are very friendly people!

Deception when booking - My wife and I had a round trip to
Prediama Castle and Postonija Cave with guide in
German language booked. Upon departure we learned that
the trip only with English-speaking guides
will. Since we don't understand English, we couldn't follow the detailed information. Serh, very annoying and the trip was for us
It's a total bust. We also had to move away from an American
Have fellow travelers berated because he felt disturbed because we tried to translate the contents of the tour guide.
Even after leaving the bus, we were still insulted.
