The most visited tourist cave in Europe is a place where the proteus or olm offspring are once again hatching. The cave railway has been operating at the cave for 140 years. The cave is connected to Predjama Castle, the largest cave castle in the world.
A legendary tourist train takes you to the underground network of karst tunnels, galleries, and halls. Postojna Cave is the only karst cave with a cave railway. For 140 years it has been taking visitors to see stalactites and stalagmites and other features created by water. During an hour and a half long guided tour, you learn about all of the most important karst features, you see the largest, 5-metre-high stalagmite known as Brilliant, you visit the most famous underground animal – the human fish (proteus).
Predjama Castle is situated in the middle of a towering cliff, a mere 9 km from Postojna Cave. Picturesque, magnificent, defiant, mysterious and impregnable, it has been dominating the surrounding area, perched high up in the 123-metre high cliff, for more than 800 years. It is listed among the Guinness World Records as the largest cave castle in the world.
