Postojna Cave & Predjama Castle
Slovenia
Destination Overview
Hidden beneath Slovenia’s Karst region lies one of the world’s most extraordinary natural wonders — Postojna Cave. Stretching for more than 24 kilometers, this underground marvel invites you on an unforgettable journey through majestic halls, fascinating rock formations, and mysterious passages carved by the Pivka River over millions of years. A unique electric cave train takes you deep into the heart of this subterranean world, where stalactites and stalagmites form breathtaking natural sculptures. The cave is also home to the famous “baby dragon” — the olm, a rare and mysterious amphibian found only in this part of the world.
Just a short drive away stands the fairy-tale Predjama Castle, dramatically built into a 123-meter-high cliff. Known as the largest cave castle in the world, Predjama is not only a masterpiece of medieval architecture but also a place filled with legends. The most famous is the story of knight Erazem of Predjama, a Slovenian “Robin Hood” who defied the imperial army from his seemingly unconquerable stronghold. Secret tunnels, hidden passages, and breathtaking views make this castle a must-see attraction.
Together, Postojna Cave and Predjama Castle offer a perfect combination of natural beauty and cultural heritage — a journey into Slovenia’s mysterious underground and its legendary past.
Throughout the journey, your driver stays on standby — ready when you are, never rushing you, never pushing an agenda. This is travel on your terms, supported by professional service.
Perfect for couples, families, or small groups who want to enjoy the coast with full control and comfort.
