Postojna Cave & Predjama Castle

Magnificent Underworld – World Famous Attraction

Take the underground train and visit the Queen of all caves


Explore the world famous Postojna Cave, located in the Karst region, only 30-minutes drive from Ljubljana. Enter the mysterious, more than 20 km long Karst cave system, with its great underground galleries and halls. Splendid cavernous halls with impressive sculptures as well as their colours will take your breath away. A part of the visit is made on an electric train and a part of it as a guided walking tour. The visit of the cave lasts approx. 1 ½ hour. The temperature in the cave is around 10°C/50ºF. Walking shoes and jackets are recommended.

Just a stone’s throw away is the Predjama Castle. Perched high up in the cliff and only accessible from one side this stunning castle truly commands the surroundings. It was a former hideout for the bold knight Erazem of Predjama, a “robber baron” and the subject of a romantic and beautiful legend. The current fortress is a Renaissance castle begun in 1583, but evidence indicates that this steep and imposing cliff has been fortified since at least the 13th century. Following your visit time at the castle and some free time you’ll return to Ljubljana, where your tour concludes.
