Slovenian One Day
Sanda was excellent, caring and informative not missing a beat. Got to know her and a little of her family life as well. Lake Bled: astonishingly gorgeous, a place not to be missed when coming to Ljubljana, the latter a lively, moving, grooving place when sun dips it’s head. As for the Caves, a bit tiring after a long day in sun. Slovenian Alps, nature at its best, mountains that leave a deep impression. Love Slovenia!

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!

Pearls of Slovenia - Postojna Cave, Predjama Castle & Piran
What an amazing tour! We got to see 3 lovely attractions in a day - from pretty Piran to the lovely Predjama castle and the oh so amazing Postojna caves! And we had ample time everywhere. We were just 4 of us and we had a great time! Our tour guide was wonderful! (Sorry - am forgetting his name! - Request if the company can check and highlight this please!) I also met a lovely girl from Finland on this tour - we were staying the same hotel! All in all the tour was wonderful!

Postojna Cave and Castle Small-Group Day trip from Ljubljana
All were fine. Pickup and return on-time. Due to almost suspense of tourism at covid I was alone and all attention was for me like in personal VIP tour. Guide was knowing interlocutor and professional driver. We visited all pleasant places by programs. I'm extra satisfied!

Postojna Cave and Predjama Castle Tour from Ljubljana
Our trip guide/driver Gal was great! Loads of information about Slovenia given and on time for the trip. Van was clean and felt spacious enough to relax. The two sites we saw were amazing. The audio guide at the castle is fantastic and the caves were excellent (little chilly, take a jumper!)

Slovenia is so green and beautiful. Even the ride from Zagreb was very enjoyable with beautiful scenery along the highway. We didn’t have nice weather when we went to Lake Bred but the tour guide managed to make it enjoyable. Highly recommended if you are in Zagreb.

Predjama Castle and Postojna Cave Tour from Ljubljana
Brilliant half day tour around the caves and castle. Even though it rained, the tour wasn’t affected as most of it is indoors. Tomas the tour guide was very good and knowledgeable too

Bled Lake with Postojna Cave & Castle - small group - day trip from Ljubljana
Excellent guide, but entry tickets were both in inclusion and exclusion list which made each individual to pay 35euro more in b/n trip , which was bit of a shocker

How to Get There

Postojna Cave is located 34 miles (55 kilometers) southwest of Ljubljana, about a 50-minute trip by road. The easiest way to visit is by private car or as part of a guided tour, but it is also possible to arrive by public transport—buses from Ljubljana stop close to the Jama Hotel, while train services connect to Postojna town (1.2 miles or two kilometers away).

When to Get There

Postojna Cave is open year-round, but the most popular time to visit is between May and October, when tours are held hourly. Winter sees fewer crowds, but it’s best to book ahead as there are sometimes only four interior tours per day.

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.
