Additional Information

Experience two of Slovenia’s highlights in one afternoon on this intimate, half-day tour from Ljubljana. Start at the thrilling Predjama Castle, mounted on a cliff overlooking the stunning Inner Carniola region. Discover the various rooms and staircases, and hear stories about the castle’s most infamous occupant, Erazem of Predjama. Then proceed to Postojna Cave. Hop on a small train that takes you deep into the renowned cave and walk through the surreal arrangement of stalactites, stalagmites and caverns guided by a local expert. The group size is limited to eight participants to maintain an intimate atmosphere. Postojna Cave, the world’s most recognized cave, is not only Slovenia’s prime tourism magnet but also one of the largest Karst formations globally. It is an essential destination when touring Slovenia. The adventure begins with a unique and exciting miniature train ride through one of the world’s most varying cave systems. With 21 kilometers of paths, galleries, and grand halls providing a remarkable underground exploration and a wide range of subterranean wildlife, including the globally acclaimed human fish (proteus anguinus). In addition to Postojna Cave, you’ll have the opportunity to visit Predjama Castle. Our guide will lead you to this outstanding medieval castle, fixed firmly in a sheer cliff in the serene village of Predjama. It’s a captivating and romantic sight year-round: resplendent with blooms and flowers in the spring and summer, draped in the hues of surrounding forests in the autumn, and radiating charm in the winter when the nearby region is blanketed in snow.

Worthwhile - Well done! Our tour guide was flexible with our goals and I am so glad we did the whole cave tour and the whole castle tour. The inside of the castle was so cool and the cave was breathtaking.

Postojna Caves & Predjama Castle - We did the half day Postojna Caves & Predjama Castle tour with Nina as our guide. Excellent all round; Nina was very knowledgeable and gave us plenty of information on the journey to the Caves. We had clear instructions on ticket purchase and meet times and Nina answered any questions we had. Caves and castle exceeded our expectations and were definitely worth visiting. We could have done with an extra 30 mins in the castle to fully complete the audio guide, but this is a minor comment. Thank you for a lovely tour. Alison & Richard

Great day out - highly recommend - I originally booked a half day tour to just see the Postojna Cave and Predjama Castle. 0820 pickup in an easy to find location and off to the Caves to start. It was a really nice group of people and our Guide - Tine - was excellent and really informative. The Caves are unbelievable and there is a moment when you're on the train and first see them that takes everyone by surprise. We then went to the Castle and again there was a !! moment when you see it emerging from the cliff. My tour should have ended after there but the day was so interesting and fun that I was able to pay the extra to make it the full day tour & stay with the group who were heading to Lake Bled for the afternoon. We had brilliant weather and were able to get a pletna boat to Bled Island before coming back and going to Bled Castle for more stunning views. Although it was a really full day, at no point did it feel rushed or that we were waiting around - just well managed and organised by Tine and a great day.

Great half day trip to 2 must see attractions! - Karina was an excellet guide! 45 min drive to the caves and then its a 10 min drive to the castle. She gave as a brief history lesson with interesting facts about Slovenia and the castle and the caves. Very enjoyable tour. Had plenty time in both attractions. Temperature inside caves is 10 C so dress accordingly! Would recommend!

Great tour to see amazing and unique places, but expensive - Great tour - was nice to have just 8 people in the van when most others were massive coaches, although unfortunately you still end up with the coach loads of people when visiting the sites, but that is tourism nowadays. However, both the cave and castle were amazing and unique places and worth the visit, even if it was rather expensive (the tour cost was transport only, we had to pay admissions too).

Guide's Ticket Scam Ruins Tour Experience - The tour was fine, but the guide cheats with the tickets. We went on a tour to Prostojna Cave with guide Branko/Branco, who was fine, but when it was time to buy tickets, our guide pulled us aside and asked us to buy tickets through him instead of the official ticket seller. We were confused, but he said he could give us a 5 euro discount. We told him we only had a card and no cash, and didn't want to withdraw money from the expensive ATM on site. He got offended and forced us to buy from him. So we had to withdraw money from the ATM, which resulted in a 100 euro fee because the ATM was a scam machine with high fees. Whether the guide collaborates with someone from the ATM company or Prostojna Cave, where he has previously worked, is unclear to us, but it is certain that he deliberately cheats and deceives his customers to make extra money. We are very unhappy with the experience and do not recommend anyone to go with this company, which uses these guides.
