Full description

Start your tour at Postojna Cave, one of the best-known caves in the world, where the underground landscape can be traversed on an electric train. Meet this underground kingdom’s most famous inhabitant, the Proteus. A fantastic web of tunnels, passages, galleries and halls, and the astonishing diversity of karst features await.

Move on to the Predjama Castle. This picturesque and impregnable castle has been perched on a 123-meter high cliff for more than 800 years. Its romantic appeal is further emphasized by the idyllic Lokva River, which disappears into the underground world deep below the castle.

The only preserved cave castle in Europe, Predjama offers a unique insight into the building techniques of the Middle Ages. During a siege that took place in the 15th century, the castle provided a refuge for its best known and most notorious owner, Erazem of Predjama. Learn about the incredible history of this castle, before you return.

“Ernie the Eagle” was a brilliant tour guide on this trip. He explained everything and all the timings, the pick ups and drop offs went like clock work. He had lots of extra facts about Slovenia for the journey (around 1hr from Portoroz). The mini bus was air conditioned and very comfy. We had plenty of time at both the castle and cave to get a really great experience!!!! There are lots of places to buy food and drinks at the caves so don’t worry too much about packing a huge amount. The castle was warm and very humid and the cave was cold (10 degrees) if you “feel the cold” then be sure to bring something warm like a sweatshirt or jacket.. especially for the short train ride down to the start of the cave tour, it’s very windy and cold!!! Once you are in the cave it’s. It so bad!
