The Basics

Visitors can discover the underground world of Postojna Cave on a 1.5-hour guided cave tour, which includes a ride on an electric train and an 0.9-mile (1.5-kilometer) hike through cave areas such as the Great Mountain, the Concert Hall, and the Brilliant Passage. Full-day Postojna Cave tours run from Ljubljana, Koper, and Bled, as well as from Zagreb or Rovinj in Croatia, and are often combined with nearby attractions such as Predjama Castle, Lake Bled, or the Skocjan Caves.

Without a doubt, do this tour!
What an amazing day! The guide and other guests were great company, but the real star was the Slovenian sites! I was awestruck by the beauty of each stop and how different it was from each of the other ones. It was the perfect way to spend the day!

Postojna Cave & Predjama Castle - Shore Excursion from Koper
Our tour guide was Dejan, he was very helpful and gave us a lot of additional informations about Slovenia, Triest, Koper etc. while driving. The car was clean and airconditioned, as promised. The driver arrived on time. The castle was magnificent, I certainly reccomend to choose a tour (like this) where you can go inside. The cave is also very beautiful.

Slovenia in One Day: Small-Group Day Trip to Lake Bled, Postojna Cave and Predjama Castle from Ljubljana
Lake Bled island, the Postojna caves were both amazing. The tour guide in the cave was less than satisfactory. He seemed ready to clock out, since we were on the last tour for the day. Not at all satisfactory!!

The Best of Slovenia, Bled lake, Postojna cave and Ljubljana
If we could give more than 5 stars we would award 11 stars. Absolutely perfect trip from the unreal cave experience, to the gorgeous castle on a pristine lake, to a picture perfect city. Robert, our guide, created an easy and fun experience all day.

Postojna Cave & Predjama Castle from Trieste
The caves and castle were fascinating, but the real highlight of the trip was our guide and the owner, Dijean. Knowledgeable, helpful with a nice local cafe/restaurant add on at the end. Awesome trip, thanks!

Postojna Cave and Predjama Castle Tour from Ljubljana
We really enjoyed our trip to the caves and to the castle in Predjama. The tickets were sorted for the caves for us. We just had to go in at the right time and really didn’t have much to worry about as the guide sorted it for us. Our guide was absolutely bonkers but highly amusing.

Slovenia in One Day: Small-Group Day Trip to Lake Bled, Postojna Cave and Predjama Castle from Ljubljana
I was had just one weekend in Slovenia and this kind of tours is perfect to see as much as you can. Nina, our tour guide, picked me up from the hotel and accompany throughout the day. Both Nina and the trip were great! Just please note all, the trip’s price does not contain entrances so you should budget more. Also, for a boat trip at Bled they do not accept credit cards, so have some cash 😉 The price might be quite high in the end, but I nevertheless recommend!

Grand SLOVENIA: Ljubljana + Lake Bled + Postojna Cave - fully Private Tour
Tanja from Viatica Travel was such a great guide. She was very knowledgeable and helpful throughout the day and even the days leading up. Since it was just me she was happy to hear what I wanted out of each stop and customize accordingly. She advised me that the cave was cold and to bring warm clothes, I'm glad she did! Every part of the day was planned to optimize your time and was flexible enough to accommodate what interests you. I would recommend this tour to anyone!

Slovenia in One Day: Small-Group Day Trip to Lake Bled, Postojna Cave and Predjama Castle from Ljubljana
Sanda was very friendly and welcoming. Lake Bled and Postojna Cave were truly breathtaking and experiences that I will always cherish and remember. Be sure to take a boat ride to the island and try Bled Cream Cake. Both are a must!

Things to Know Before You Go

  • Guided tours are available in four different languages and audio guides are offered in 17 languages.

  • Temperatures inside the cave average 45–50°F (8–10°C) even in summer, so it’s recommended to bring warm clothing and wear comfortable walking shoes.

Highlights of the Postojna Cave Park

After exploring the beautiful caves, pay a visit to the nearby Predjama Castle, the largest cave castle in the world. Then, visit the Proteus Vivarium to discover the large number of animals that dwell in the caves, including the famous olms or “baby dragons.” Other highlights include the EXPO Postojna Cave Karst, an exhibition on the cave’s unique karst landscapes, and adventure tours of the neighboring Pivka Cave and Black Cave.
