Postojna Cave Tour

Explore the Magnificent Underworld

The Queen of all Caves 


Explore the world famous Postojna Cave, located in the Karst region, around 70-minute drive from Slovenian coast. Enter the mysterious, more than 20 km long Karst cave system, with its great underground galleries and halls. Magnificent cavernous halls with impressive sculptures as well as their colors 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.

Continue on for a beautiful photo stop and some free time at Predjama Castle. Perched high up in the cliff, this castle dates back to the 16th century, but evidence indicates that this steep and imposing cliff has been fortfied since at least the 13th century. Following your time at the castle you’ll return back to your starting point where your tour concludes.
