Due to their exceptional significance, the Škocjan Caves entered UNESCO’s list of natural and cultural world heritage sites in 1986. International scientific circles have thus acknowledged the importance of the caves as one of the natural treasures of the planet Earth. From time immemorial, people have been attracted to the gorge where the Reka River disappears underground as well as the mysterious cave entrances.


The Škocjan caves have an extremely complex system of cave passages having over a total length of 5.8 km. The caves are the biggest and best-known natural phenomenon in the classical Karst area.

With the shifting of sinkholes in the geological past, numerous collapsed valleys have formed at the contact point where flysch meets limestone under the caverns. With a depth of 163 meters, Velika Dolina and Mala Dolina charm every visitor.


The finest view of both valleys, with the natural bridge and the cave that separates them, is gained from an observation point. The caves, with an immense underground gorge and halls, are the beginning of the Škocjan underground system.


These caves probably have the biggest cave hall in Europe, measuring 12,000 square meters (1.2 hectares) in cross-section. The Reka River runs underground for almost 40 kilometers, to the sources of the Timav in the Gulf of Trieste (Italy).


Visitors are led on a tour of the Skocjan Caves by fully-qualified guides. The tour takes an hour and a half and an explanation is given in the English language.


On the surface, ancient barns housing ethnological, karstology, and archeological exhibitions await your visit. You can also walk through the park, marvel at its natural and cultural sights, and enjoy its unspoiled nature on the Škocjan Education Trail.
