Postojna Caves & Predjama Castle (admission fees included)

People on the tourist train in the cave.

Are you craving the unforgettable! Forget the ordinary. An irresistible combination awaits you, offered by the Slovenian Karst: ride the little train deep into the mysterious underground kingdom, then ascend to the castle carved into the very heart of the cliff.

Start your Slovenian underground and medieval exploration at Postojna Cave Park. The subterranean train will take you deep into the magical world of amber stalactites and stalagmites. Admire the famous Brilliant stalagmite, the symbol of Karst beauty, and meet the unique inhabitant – the mysterious Olm (Proteus anguinus)

From the magic of the underground, your journey leads you to the largest castle built in a cave in the world. Predjama Castle is not just located near the cave – it is partly built within it! For over 800 years, it has proudly defied time amidst a 123-meter-high cliff. Walk through the old castle rooms, the armory, and discover the secret passages that once provided the castle with unbeatable defense.

This is the perfect trip for couples, adventurers, and families who want to see the most spectacular sights that the Slovenian Karst has to offer!
