Postojna Cave 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. A fantastic web of tunnels, passages, galleries and halls, the 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.

Postojna cave is the richiest cave I have ever been to. But the visit was a horrible experience for me, because people were violating all the security rules (touching dripstones, using flashlights...) and guides didn't take care (even when I spoke to them). It's so sad that the Postojna caves' stuff is there only to get money from the people... More

What a fun day trip!!! The caves are incrediable! My only advice is to be on time for your departure time. We arrived at the exact time of departure. But guess what, we were too late and had to catch the tram into the cave with a non English speaking tour. No biggie! But really!!! You better arrive 5-10 minutes... More

A friend and I drove from Trieste to Slovenia for the day; Postojna caves was one of our destinations. It's definitely a world attraction and there were people there from all over the world. After buying your tickets (and making sure you have warm clothes), you join your tour group, which is organized by language. The group leader provides a... More

I've been to many caves through out the world and this is the most beautiful and largest yet. A real plus is there are no steps, only a continuous cement pathway after getting off the train. I didn't have to be cautious about tripping. In a way it is sad because it is so commercialized. Yes, some people didn't follow... More

The caves are absolutely beautiful. We visited in July and the caves were a welcome relief from the extreme heat. The children loved the train ride into the tunnel. And were astounded at the size of the caves. The guide was great and offered an interesting history of the caves and there different uses throughout history. We would definitely recommend... More

For me, it was a disappointment. I am a tour guide in a small but very spiritual cave. We only allow 20 people on a tour of one of the tours and 14 in the other tour. This cave seemed very commercial to me. Loads of people, separated by languages, English, German, French, etc...you board one of two electric trains,... More

Visiting Slovenia? then the postojna Caves is a must. The caves have more than 21 km tunels inside but all are not open for daily tours. Tour takes about 1 hour and the caves provides spectacular chambers with huge formations of stalagmite, some are as high as 18 meters and it has taken the evolution about 100 K years to... More
