Postojna cave Park

Postojna cave

Take an unforgettable ride on Postojna Cave’s underground train. Experience a fascinating subterranean paradise shaped by tiny droplets over millions of years. Postojna Cave is the only place where you can see the most precious brilliant in the form of a cave formation and also meet the baby dragons. Just like the world above the surface, Postojna Cave boasts towering mountains, murmuring rivers and vast subterranean halls. It is a real challenge for explorers and the cradle of speleobiology.

Postojna Cave is open daily, including on public holidays. The cave tour, which includes a cave train ride and a walk along an easy footpath, takes an hour and a half. Each Postojna Cave tour is accompanied by tour guides, who provide visitors with tour commentary in Slovenian, Italian, English or German, presenting the cave’s splendours in detail. Visitors can also use audio guides available in no fewer than 17 languages. Cave tours are suitable for all visitors, including families with young children and visitors with mobility impairments. The temperature inside the cave is constant throughout the year (10 °C), so warm clothing and sports footwear are recommended.

Predjama Castle

A mere few kilometres from Postojna Cave, the Karst world offers an unforgettable experience in the fairytale world of knights. The impregnable medieval marvel has been perched in the middle of a 123-metre-high cliff for more than 800 years. Behind the largest cave castle in the world, there is a network of secret tunnels, from where the knight Erazem of Predjama would set out on his plundering expeditions. The Cave under Predjama Castle is the home of a colony of bats.

EXPO Cave Karst

Visit a fascinating interactive exhibition, which will guide you through the extraordinary events and a series of coincidences that resulted in the creation of this subterranean natural miracle.

Special attention is devoted to our youngest visitors, who are guided around the exhibition interactively by an olm and a slenderneck beetle. Children can also try their hand at driving a real cave train.

As part of the Expo Cave Karst exhibition you can see two other exhibitions for free: Life within a Billion Years, and Butterflies of the World.


Postojna Cave is inhabited by over 150 animal species. You can meet some of the most interesting ones up close – the undisputed star among them is the olm.

The Vivarium is located in the Passage of New Signatures, fifty metres from the entrance to Postojna Cave. It consists of two parts. The research part, the so-called laboratory, is used for scientific work and research. The speleobiological exhibition housed in the Vivarium’s exhibition section presents the basic concepts of karstology and speleobiology, special features of the subterranean environment and the most typical representatives of our cave animals.
