Predjama Castle is built into a towering rock face, its white façade, grey roof, and traditional shutters blending seamlessly with the cliff. The coat of arms of the castle’s last noble family adorns the façade, while below it lies the entrance to the Cave beneath Predjama Castle.

Cave Beneath Predjama Castle

The Cave beneath Predjama Castle is the second-longest tourist cave in Slovenia, stretching through several levels beneath the towering cliff into which the famous Predjama Castle is built. Around 14 kilometres of passages have been discovered, with approximately 700 metres open to visitors. The tourist route leads through fascinating sections of the cave, including the Horse Stable, Main Passage, Passage of Names, Great Hall, and Fiženca, where the cave opens back onto the surface. Spread across four interconnected levels, the cave reveals a spectacular underground world of chambers, passages, and dramatic karst formations.

The cave is closely linked to the history of Predjama Castle. In the past, its passages served as secret escape routes and hiding places, while today they offer visitors a fascinating insight into the underground world of the Karst. Visitors explore the cave using handheld torches, as there is no electric lighting inside, making the experience even more authentic.

Guided tours are available mainly during the summer months (typically from June to August). For the protection of hibernating bats, the cave remains closed to visitors during the rest of the year.
