Postojna Cave

Two million years in the making, Postojna is one of the great show caves of the world — and the only one you enter aboard a little electric train, which has rattled through the dark since 1872. Beyond the platform, 24 kilometres of passages drip with stalactites, among them the dazzling white five-metre “Brilliant”. Watch for the olm, the pale, blind cave salamander locals once swore was a baby dragon. Well over 40 million visitors have made the trip.

Postojna Cave is a one-of-a-kind natural wonder located in the Karst region of Slovenia. This awesome cave is famous for its unbelievably beautiful millions of years old dripstones and other incredible cave formations. People have been visiting Postojna Cave for over 200 hundred years, making it one of the oldest show caves. The world’s first underground railway was constructed here and it’s still the main means of transport. On entering the cave, you board a little train that takes you deep into the underground. Then you explore the cave’s miracles on foot.

“Human Fish” – Postojna wildlife

Speaking of miracles, Postojna Cave is home to a species called proteus or olm, an endemic amphibian creature also known as the human fish in Slovenian translation and lovingly dubbed the “baby dragon”. Yes, this cave actually has a tiny dragon dwelling in its depths. Enter and be amazed!

Postojna Cave is also home to a wide array of other interesting species living in its underground maze of passages. From various types of bats to unusual insects.
