🌋 Guided walking sections through massive chambers
🐉 A chance to see the famous “baby dragon” proteus, a rare cave-dwelling salamander
🧥 Constant temperature of around 10°C — bring a light jacket!

Just a short drive from the cave lies Predjama Castle, perched dramatically in the middle of a 123-meter-high cliff.
It’s not only one of Slovenia’s most photogenic spots but also one of the most unique castles in the world — built directly into a mountain!
Inside, you’ll explore:
Ancient rooms and medieval passages
A secret tunnel used by the legendary knight Erazem of Predjama
Breathtaking views of the surrounding valley
This is a place where history meets mystery — and it’s part of every Postojna Cave day trip.
