the caves
The most captivating cave in the world and the largest show cave in Europe! While touring the 24-kilometre-long cave system, you will get to feel the magic of the underground world and experience a one-of-a-kind ride on Postojna Cave's underground train.

Olms have been captivating people's imagination since time immemorial and legend has it that they are actually baby dragons. They remain something of a mystery even today and are considered the largest cave-dwelling animal that can go without food for up to 10 years.
A mere few kilometres from Postojna Cave, the Karst world offers an unforgettable experience in the fairytale world of knights. The impregnable medieval marvel has been perched in the middle of a 123-metre-high cliff for more than 800 years. Behind the largest cave castle in the world, there is a network of secret tunnels, from where the knight Erazem of Predjama would set out on his plundering expeditions.
Natural elements seamlessly interwoven with manmade ones, the result of man's work and nature's creativity has created a pearl of medieval resourcefulness. The world's largest cave castle, listed as one of the Guinness World Records, tells a picturesque story about the times when comfort had to give way to safety, and when the clatter of weapons would often drown out troubadours' songs.
