Postojna Cave

A world-famous tourist attraction located in the Municipality of Postojna is the remarkable Postojna Cave, an underground paradise of stalagmites and stalactites. With its 24 kilometres of passages, galleries and magnificent chambers, it is one of the most diverse cave systems in the world. During your visit you will see the most beautiful stalagmite in Postojna Cave, and you will also have the opportunity to see a "baby dragon" – otherwise known as a "human fish" or olm – with your own eyes. Another special feature of Postojna Cave is that it is the only cave in the world with its own two-track railway. A visit lasts an hour and a half. Guided tours are available in four languages, with auto-guides available in a further 17.

The part of the cave that is today open to visitors was discovered in 1818 by a local man: a cave guide called Luka Čeč. Today the cave is the most visited show cave in Europe and Slovenia's number one tourist attraction. More than 38 million enthusiastic visitors from all over the world have passed through the cave to date. 

During a visit lasting an hour and a half, visitors pass through a full 5 km of cave passages, including 3.7 km aboard the cave train. Visitors are advised to dress warmly because the temperature in the cave ranges from 8 to 10°C. 

Postojna Cave boasts some remarkable underground chambers. During the Christmas season, one of these chambers hosts the world's largest underground tableau vivant Nativity scene. This Christmas presentation amid the stalactites and stalagmites involves more than 500 participants!

"Brilliant" stalagmite in Postojna Cave

Did you know that the five-metre-high "Brilliant" is considered the most beautiful stalagmite in Postojna Cave and also serves as a symbol of Slovenia's karst region?

It stands in a place where water drips strongly and steadily through the cave ceiling. 

The water that slides over the rounded apex of the stalagmite deposits a thin layer of pure calcite – constantly and evenly – which is what gives the stalagmite its gleaming white appearance. 

As you gaze at this five-metre jewel you will simply have to agree that it deserves its name.
