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.
