About the activity

Embark on a journey to Slovenia's most renowned cave system, the Postojna Caves. This vast, 21 km long network, millions of years in the making, offers unparalleled accessibility. Your adventure begins with an electric train ride, followed by a guided walk through magnificent halls adorned with stalactites, stalagmites, and delicate formations. Discover the unique Proteus Anguinus, a rare amphibian often called the "baby dragon." Emerging from the underground, your tour continues to the dramatic Predjama Castle. Perched precariously on a cliff face over 100 meters high, this ancient fortress holds centuries of secrets, legends, and myths waiting to be uncovered. The scenic drive back to Ljubljana will take you through picturesque green landscapes.
