- 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.

Amazing castle and cave - Amazing experience at both the castle and cave. Castle is even more impressive in person with lots on exhibit and overall grandeur. Cave has an amazing variety of formations with many great photo ops. Highly recommended!

Absolutely worth your time if you're in Trieste - Truly an experience not to be missed. Dejan picked us up in Trieste and drove us into Slovenia, first to Predjama Castle and then to Postonja Cave. Postonja Cave in particular was astonishing; even if you don't think you're interested in caves, you should see it. Dejan was also delightful, providing anecdotes about the history of the region. The beginning of November was a good time to visit, as neither site was overwhelmed with visitors.

Fabulous tour - The best exploration tour we had in 16 days of traveling the Mediterranean! Castles, caverns, and guide! We were 4 older adults traveling from Trieste. The castle is so much more than castle - it is also built into a cave and hillside. Stunning and historical. The cavern is beyond compare. Immense, gorgeous, the most incredible stalactites and stalagmites. Very well run with a train inside the cavern to go down and up and about a 1.5 mile walk inside. Beautiful in every way. Our guide was knowledgable about all of the area around us, pleasant, well spoken, intelligent, and excellent in every way. We could not have enjoyed it all more!

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.

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!
