A Cave Like No Other
Discovered in the 19th century but inhabited since prehistoric times, Škocjan is nothing like a typical show cave. The tour takes you through silent chambers with delicate formations before crossing the Cerkvenik Bridge — suspended 45 metres above the roaring underground river in a pitch-dark canyon. The noise and sheer scale are unforgettable.
Škocjan is also an important archaeological site, with evidence of human habitation dating back 10,000 years. The Bronze Age settlement and Iron Age necropolis found here are among the most significant in southeastern Europe.
