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 Postojna Caves are a very interesting natural phenomena and well presented. Unfortunately the website doesn't really tell you what to expect. Yes there is a 3.5km train ride (in & out), the train is long & small, but it still passes as a train....More
