Ride on a double-track railway through the underground tunnels of Postojna Cave and see colorful rock formations, as well as the 100 species that make the caves their home. One of the largest caves in the extensive karst plateau features 21 km (13 mi) of passages, galleries, and chambers illuminated by electric lighting. A historical train takes you to large halls adorned with chandelier-like stalactites and limestone "sculptures," such as "the brilliant," a shiny white limestone formation. Meet the olm, a salamander popularly called the dragon's offspring or the human fish. Archduke Ferdinand I was the first to officially visit the cave in 1819, but several writings on the cave walls date all the way back to the 13th century. Note that audioguides are available in a range of languages. Discover how to plan a Postojna trip in just a few steps with Inspirock's itinerary builder.

I was not too thrilled to have to see “a cave experience.” I really enjoyed it however. A train ride down down down twisting and turning: just like in ‘Indiana Jones.’ Then walk for about an hour in a... more »

One of the best place to visit in Slovenia. Equally enjoyable for both children and adults. You can purchase tickets online easily and faster. Best experience in lifetime. Also you can buy souvenir items which are available at a reasonable price. Cave system will rail access is just wonderful. Guided tour is really informative and you have it in different languages too. Overall it was the best experience.
Touristy - yes. Breathtaking, also a strong yes. I have been there twice, some ten years ago and in August 2019. What an amazing cave, they are very efficient and well organized - although the big crowd you get a very good tour.
Very nice tour. Better be there 15 minutes before tour start, otherwise you need to pay a conversion fee to go with another group. Buying the tickets online will definitely save you some time.
Great and unique experience. Nice views. But after a few minutes, I felt a bit bored as all the views are similar. The organized tour was good. It is recommended to book online in advance as you may need to wait for more than an hour to enter.
An exceptional cave system. In the guided tour one only sees a very small proportion of the overall 24 Km of the system. Do buy tickets online in advance and make sure to arrive at least 20-30 minutes before your allotted time to allow for parking and walk to the cave entrance. The vivarium and expo were interesting and provided a way for us to have something to see and do whilst waiting for our entry slot. Temperature in the cave is 10 Celsius and you may therefore want to bring an extra layer for yourself or children. Postojna Castle is a few Km away and there is a shuttle between the cave site and the castle (hourly on our visit) available though I drove between sites. A combined ticket for it is an option for it when purchasing the cave tickets. This is a highly commercialised site and value for money is questionable with entry varying from about 30-50 per person depending upon which options you choose at entry. Parking at the cave was an additional 5 Euro. There was no charge for parking at the castle. Our guide in the cave was very good. I spoke to her and found she was very knowledgeable. If like me you like caves and the glorious stalagmites, stalactites and curtains formed over hundreds of thousands of years then do visit.
