- 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 worldâs 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 kingdomâs 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.

Fascinating and enjoyable trip to the Postojna Caves & Predjama Castle - In spite of a couple of blips beforehand (not giving the start time until the day before plus not seeing our change of email address), we enjoyed this trip very much. Ernest was an excellent guide, full of knowledge about the sites and also generally about Slovenia. We loved his pride in being Slovenian, a beautiful country which we love. The caves were amazing and the train trip in and out was great fun. Also the castle was incredible. Thank you Ernest, we had a great time!

Slovenia castle , caves and coffee- worth the trip - The Koper Tour operator was terrific. Picked us up at our hotel and gave us an informative and pleasant ride from Trieste to Slovenia and oriented us for the two wonderful tours.

Simply amazing! - Photos on the Viator website, which are stunning, cannot fully capture the exterior beauty of the castle and its property. The interior was amazing. The audio guides were a great addition.
The cave journey was beyond expectations. We’ve been to several on the US, but the magnificence of this one was overwhelming. A true wonder of nature! Definitely a “don’t miss” excursion!

Well Worth the Trip to Trieste for This! - We were picked up in front of the Savoia Hotel by Matias, our drive, who is Slovenian and speaks Slovene, Italian and English! The hour-long drive to Predjama Castle was beautiful; such a gorgeous country. The Predjama Castle was quite interesting and in a unique setting. Then onto Postojna Cave which was prodigious...HUGE. It was quite cool on the train so don't forget your jacket and good walking shoes.

Interesting tour - Matthew from Koper was our guide. He picked us up promptly from Trieste. We had a lovely drive to the castle and then cave. He gave us interesting information about the region. We thoroughly enjoyed the tour and Matthew was a good guide.

Great tour - The cave and the castle were both amazing....well worth the drive there. I just wish we had more time at the castle as it felt a bit rushed.
