Postojna Cave, Slovenia – Wonder of Nature

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, which has already reached 35 million in 200 years.

For 140 years, the Postojna Cave, as the only cave in the world, offers a unique and adventurous ride with a special train, which will take you into the cave, under spectacular underground arches, which are embellished with chandelier look-alike stalactites, through a beautiful subterranean world full of playful limestone sculptures.

21 km of passages, galleries and magnificent halls offer a unique experience of the underground world. The Postojna cave is definitely one of the most diverse cave systems in the world.

The most beautiful stalagmite in the Postojna cave is called the Brilliant. Looking at this marvellous, shiny white limestone formation, you simply must agree it is fully worthy of its name.

The unusual looks of the olm have always sparked our imagination. At first it was believed that they were just baby dragons which the high tide brought to the surface. As a matter of fact, there might be some truth to these old beliefs.
