- Postojna Cave - Over 2 million years, the Pivka River has sculpted the Postojna Cave. As the water level fluctuated, it created a stunning “multi-level” subterranean world adorned with stalactites, stalagmites, columns, curtains, and other magnificent formations, formed by layers of limestone left behind by the receding water.
The cave’s first visitors are believed to have arrived as early as the 13th century, with the most beautiful sections discovered in 1818. Visitors enter the cave by train, with a ride lasting about 10 minutes, followed by a guided walking tour. Walk beneath the delicate, transparent tubes hanging from the ceiling in the Hall of Tubes.
From beneath the Russian Bridge, you will reach The Concert Hall, where you can admire the stunning white Brilliant – a truly awe-inspiring sight.
Despite the darkness, around 100 animal species inhabit the cave! The main attraction is the proteus, initially mistaken for a baby dragon.

Predjama Castle - Before your visit, relax on the terrace of the country inn in front of the enigmatic Predjama Castle, built into a rock, and enjoy its breathtaking views.
The castle is designed as an impregnable fortress, situated in the mouth of a cavern halfway up a 123 m cliff. It features remarkable elements – holes in the entrance tower’s ceiling for pouring boiling oil on invaders, deep and damp dungeons, and a spooky hiding spot at the top known as Erazem’s Nook.
After a delightful half-day experience, the tour will return to Ljubljana.
Drop-off will be at the same location as pick-up.
