Your guide will pick you up at the agreed starting point in Koper, Slovenia - hotel, cruise terminal, bus station, train station etc. (please contact us after the booking so the appropriate arrangements can be made).

Postojna Cave
Admission included120 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 included120 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.

The cave was spectacular, easily walked, great guide. Jaw-dropping was the length of the cave, and the tram ride was only the first and last ten minutes of the excursion.

The cave was awesome!! We should have had more time at the castle. It was very rushed and didn’t have time to explore everything we wanted.

Magical trip into the past!

There was a lot of stairs and dress warm for the cave experience, but it was awesome! This was a lovely trip!

Challenging cave walk; tour of castle ruined by numerous rude school children.

This is not a moderate activity; it is challenging. The guide was nice but was subpar based upon other Viator guides we have had on many other tours.

Very interesting sites.

The bus host Andrea was a nice man. The guide in the cave was extremely hard to hear, but the cave was spectacular! The castle used audio guides in each room and was pretty amazing!

Ernie from Koper Trips was great guide

The guide Ernie was very helpful and cheerful. Ernie gave us the relevant info to give us the context to better appreciate the two amazing places (Predjama Castle and Postojna Caves) covered in this tour. The company's pick-up from Piran was very helpful too as the tour started from Koper. I'd strongly recommend Koper Trips. Very service-orientated company. Thank you.
