The first stop on our day trip will be the Postojna Cave, the most famous Karst cave in Slovenia and get the chance to see its world-famous “baby dragon”.

It starts with a train ride on the world’s first railway in an underground cave. It will take you deeper the cave, where you will hop off and continue on foot. You will be able to explore the magical underground world of stalactites and stalagmites, walking through fairytale-like halls, the oldest underground post office in the world, and more.

But something even more interesting is waiting for you in the caves … a dragon!

Oh, maybe not a real dragon, but the legends call it a “baby dragon”. Its real name is olm, but people also call it a “human fish” because of its skin-like colour. It’s an aquatic salamander that lives in the Postojna cave and is the largest cave animal in the world that can live without food for up to 10 years. As it is blind, it won’t be able to see you, but hopefully, you are lucky and able to see them.

After emerging from the underground of the Postojna Cave, we will take a short drive to the Predjama Castle, the largest cave castle in the world.

This castle stands in the middle of a 123-metre high cliff and is more than 800 years old. The rebellious robber knight Erazem of Predjama lived here, where he was able to resist the imperial siege for over a year. There is also a large network of secret tunnels behind the castle, connecting with the cave below it.

Come and discover the castle’s secrets with us!
