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.

Huge cave, lots of formations, good infra-structure and the Proteus!

When we saw the price to visit the cave we were surprised and wondered if it would be a good investment or not. It certainly it! We have visited several caves in South America but... read more

When we saw the price to visit the cave we were surprised and wondered if it would be a good investment or not. It certainly it! We have visited several caves in South America but this one is probably the most impressive. The infra-structure is amazing (you even get inside and outside the cave with a train). The amount of...

Saw the caves as part of a half day tour from Ljubljana. What a great experience- the guide in the caves was excellent- so witty and interesting. The caves are gorgeous, and its an easy walk, although quite a steep uphill bit at the start. There are no stairs, only sloped pathways, so is wheelchair and pram accessible. A constant... More

We did a tour to Postojana caves. At first i was not sure whether I wanted to go - I had read that they were very touristy and the idea of a train really sounded cheesy. But i'm so glad we did. It is a very touristy site - but well organised. At the beginning, there are cafes, shops and... More

These are the largest caves in central Europe. I mean really, really big. A lot of the tour was done by train, which was a lot of fun. Then there was about 2 hours of walking that was not too strenuous. I'll be honest, it was all a bit samey by the end. But you can't complain, it's a cave!... More

Amazing cave, probably the most beautiful in Europe. It's really huge and worth of your time and money. First you hop on a train which takes you to starting point of your visit. After that is mostly walking. We were in a small group so we had enough time to take pictures and admire the caves. And to say the... More

This cave is very interesting. It is better to make reservation via web site. Ticket cost about 23 eur and include drive by train, guide in English, Italian, German or Slovenian. If you do not understand any of these languages, you can use audio guide ( 3 eur per person). Tour last about 90 minutes. Parking for a car cost... More

Very interesting natural site, very well maintained and easily accessible even for strollers and wheelchairs. The basic tour (23,90 € per person) includes an itinerary of 2 km by train and a walking guided tour in your own Language through another km of caves. The walking tour takes 50 minutes approx., my 4 year old son went through easily and... More

I first visited this stunning gift from nature when I was (much) younger and when this country was still part of another country. It was insanely humbling to be able to see it again as an adult and with my little niece. At both times, the feeling was of awe, appreciation and humility. It is a wonderful experience for both...

I visited the caves on two different occasions, on a regular tour this Summer and this week with Nativity Scenes happening in the cave. Both times the cave is an incredible sight to see, enormous cave, with rich cave forms that leave you speechless. The Nativity scenes colour the cave in different lights, and the story they show is really... More

We arrived a little early and sat in the nice little cafe. When we went into the caves we were split into languages, very well organised. The train ride was excellent although I think a safety talk before hand would be of benefit to some as the caves were a little low at times. I couldn't believe how stunning and... More
