- Explore Postojna Cave — one of the most famous cave systems in the world.
- Visit Predjama Castle, the largest cave castle in the world.
- Meet the mysterious olm, the rare “baby dragon” found only in Slovenia.
Nature’s masterpiece and a castle straight out of a fairy tale — all in one unforgettable adventure with your Blue Guide!

Step into a world of underground wonders and medieval legends.
Postojna Cave is not just any cave — it’s one of the most famous in the world! Ride a unique underground train into a stunning karst world carved by water over millions of years. Wander through gigantic chambers, marvel at sparkling stalactites and stalagmites, and meet the mysterious olm, also known as the “baby dragon” — a rare, blind cave-dwelling creature found only here. The experience is magical, cool (literally — bring a jacket!), and completely unforgettable.

After the depths, rise to the cliffs with a visit to Predjama Castle, the largest cave castle in the world. Perched dramatically in a sheer rock face, this Renaissance fortress is filled with secret passages, hidden tunnels, and stories of rebellious knights. Most famous is Erazem of Predjama, Slovenia’s own Robin Hood, who defied the emperor from this very castle.
The mighty Predjama Castle has stood for over 800 years in the middle of a 123-meter-high rock wall. It is listed in the Guinness Book of Records as the largest cave castle in the world. Predjama Castle was first mentioned in 1274, and is considered the only fully preserved cave castle in Europe.
This mighty castle has been the setting for numerous documentaries and feature films, including Armor of God starring Jackie Chan. Inside, you can see replicas of weapons and armour from the Middle Ages.
Whether you’re a nature lover, a history buff, or just in it for the epic photos, this tour offers the perfect mix of natural beauty, mystery, and medieval charm.
