The Postojna Cave Park

The Postojna Cave Park is located just 49 kilometres from the Slovenian capital, Ljubljana. The route first takes you to the wonderful underground kingdom of the Postojna Cave, with its spectacular halls, diverse stalactites and mysterious species of animals. Only a few kilometres away, embraced by a mighty rock, lies proudly the Predjama Castle - a medieval marvel that has defied time for over eight centuries. And yet, this is just the beginning ...
The Postojna Cave is considered one of the most attractive caves in the world with its magnificent stalactite sculptures and diverse animal world.
Only in the Postojna Cave can you get a close look at the most precious diamond in form of a stalactite and meet real baby dragons. The Postojna Cave has its own mountains and inside the cave, rivers run wild and huge halls expand just like on the surface, making the cave a challenge for researchers and a centre of world’s biospeleology .
You can travel through the cave on an underground train, which runs along a 3.7 km long route, the only two-track cave railway system in the world.
If you visit the Postojna Cave at Christmas time, you can experience the exhibition of a live nativity scene.
Just a few kilometres from the Postojna Cave, the world of Karst offers an unforgettable experience in the magical world of knights. More than 800 years ago, an impregnable medieval marvel was carved into the 123 m high vertical wall. Behind the largest cave castle in the world is a network of secret tunnels, which served as starting points for the raids of the infamous knight Erazem Predjamski. Bats also found their home in the Cave under the castle.
The constant interweaving of the natural with the artificial, the work of human hands and the creativity of nature, forms a gem of medieval ingenuity. The largest cave castle in the world, entered in the Guinness Book of Records, vividly describes the story of a time when comfort had to give way to safety and when the sound of weapons often silenced the songs of troubadours. So special and unique that it ranks among the ten most fascinating castles in the world.
