The Postojna cave (Postojnska Jama) is located in Postojna, Slovenia. About 30 mins from the capital Ljubljana. It’s the second-longest cave system in the country as well as one of the world’s top tourism caves.
A fascinating underground route to the discovery of the world of huge stalactites and stalagmites, underground rivers, rock formations and underground halls. A haunting beauty that seems to come from a fantasy movie.
The place has its own large parking lot divided into areas (for buses, cars and motorcycles). And it’s not free! It’s free for 45mins (obviously you can not visit the cave for 45mins). After that you have to pay an acceptable fee of 3,50€.
Ticket cost €23,90 per adult only for the cave. But you can also combine your purchase with the ticket for the nearby Predjama Castle, and others different combinations in which also include lunch. Children under 5 years old pay only 1€.
Since the visits are limited by the number of people at a time, you have to reserve what time you want to go. And visitors are divided into groups based on their prefered language.
