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.

The critics don't lie! This place is incredible and a must see for all travelling through the Slovenia. To avoid the long line ups and crowds, arrive early and if possible purchase your tickets on line. We were there before 10 am and had a hassle free entrance into the caves. Please remember your jackets, but for €3 you can... More

We had read the reviews before arriving but we're still blown away by the caves. Bring a sweater as it was 7 degrees in the caves which was a big difference to the 25 degrees overground. There are a number of other attractions to choose from apart from the caves as part of a bundle ticket. We chose the underground... More

The caves themselves are truly incredible, how they were formed by raging rivers flowing down from the alps, running through the limestone to continue both above and below ground...the formation of the caves is very much worth seeing. The Postojna caves have become such a popular destination, they have made a small themed-park out of the area and are capitalising... More

I had visited these caves in 1990 and was just as impressed again this time. While the walkways have been improved, the natural beauty is still amazing. Quite a surprise to be riding a train deep into a natural cave. Despite being quite arthritic, I was able to complete the entire quided walk I was impressed by the guides attention... More

As many other reviewers have noted, the complex is amazing. There are many stalactites and stalagmites plus other extraordinary structures and the train ride is excellent. But, the caves are such a major draw that the numbers of visitors is a little overwhelming. The crowds are quite well managed initially, although queuing for our timed entry was a little chaotic,...

These caves are really awesome. The depth that you get into these caves is also impressive. It was an extensive tour of the caves, over 90 minutes and well worth the price. Definitely worth a day visit if you are in Slovenia.

I strongly recomand a visit if in the area. Very well organized with tour guides in more languages. Accesible prices, very nice people and a unique location. The guides give you useful information. There is a unique species of salamander in the cave and they even have funny toys with it. All of us and esspecially the child enjoyed it... More

Postojna cave is one of the longest caves in Slovenia. With its 24km long tunnels it is perfect for people who look for adventure and fun. Take warm clothes with you otherwise you can buy or rent some grom there. Inside the cave you will feel like a tousand years before. It is perfect either for families and alone hikers.

I just love this cave. Really nice experience, from mini train, walk and chilling temperature. Best place to see something and feel good during hot days:) We are going here quite often
