Postojna Cave: the wonder of the Karst

Postojna (14,500 inhabitants) is a town located in Slovenia just 35 km from the border with Italy and 45 km from Trieste. Postojna has become especially famous for its wonderful cave. These wonders of nature were open to the public since the 19th century. Subsequently in 1872 to make easier the visit the caves were equipped with a small railway.

The Postojna cave system was created by the underground river Piuca (Pivka in Slovenian). This river enters the ground near the Postojna caves and after about five kilometers it flows again into the open air near the village of Planina.


The caves measure over 20 km in length and are one of the natural wonders of the Karst. The caves are especially interesting for the variety of shapes of limestone concretions, i.e. the stalactites and stalagmites, and for the size of the caves. The maximum depth of the cave is finally 115 meters.

The visit of the caves is simple, the itinerary that is without large differences in height is completed in 1 hour and 30 minutes. A first 3.5 km stretch is done with an electric train. While the remaining 2 km are done on foot. Inside the caves the temperature is around 8 ° C and the humidity 95%. For the visit it is better to equip yourself with a waterproof (you can also rent them at the entrance).
