Mysterious Underworld & most unique Castle

Enter the mysterious Karst region – an underground world with 20 km long system of caves and halls, the greatest show-cave of Europe and worldwide known natural wonder! A train ride through the underworld will impress you beyond imaginable. Masterpieces of nature will leave you breathless: stalagmites and stalactites in all possible forms, lime veils in different colours, stone spaghettis hanging off the ceiling, the magnificent Concert Hall… And more!
Do not forget to take warm clothing and comfortable shoes!
Around 9 km away, one of most picturesque and impregnable castles in Slovenia is located: the Predjama Castle. Casted in the 123 meter high rock it is guarding an access to the cave system, and with its famous legend of a robber-knight Erasmus Predjama is definitely a place filled with fantasy.
