Postojna Cave is one of the top natural tourist attractions in Slovenia and the most visited cave in Europe. Offering more than 20 km of passages, it is the second-largest stalactite cave developed for tourists in the world. Since its opening to the public in 1819, more than 35 million ‘adventurers’ have visited the karst cave – on foot or taking an exciting ride on the cave train. Today, the unique underground world is managed by Postojnska jama d.d., a dynamic enterprise with a successful strategy for growing visitor numbers further while being firmly committed to preserving the show cave for future generations.
