Your tour begins at your Ljubljana hotel, where you’ll board a climate-controlled vehicle destined for Potstojna Cave. On arrival here, you’ll board an electric train and embark on a journey through one of Slovenia’s most popular attractions.

Dramatic stalactite formations, limestone curtains, and mysterious passages demand attention and cavernous voids seem to swallow you whole. After the train ride, spend some time exploring the caverns on foot before you proceed to your second stop.

Following a short journey, arrive at Predjama Castle — a mysterious, 800-year-old landmark perched impregnably at the mouth of a hillside cave. Take a guided tour of the unconquerable castle, the largest cave-castle in the world, to see armory and richly furnished rooms, and to learn the legend of Erasmus, the Slovenian rebel associated with the castle.

Your tour concludes with drop-off back at your Ljubljana hotel.
