What to expect

Take a train ride into the underworld labyrinth of passages, tunnels, galleries and chambers, dotted with stalagmites, stalactites, and columns of incredible shapes and sizes. Immerse yourself in a medieval legend of knight Erazem in Predjama Castle. Enjoy a walk through the vibrant streets of the capital Ljubljana.    

Postojna Cave is the best-known cave in the world. It is also the greatest tourist attraction in Slovenia and one of the world's largest Karst monuments. What makes Postojna cave a must-see attraction of Slovenia? Starting with a unique and adventurous ride with a special train, it is one of the most diverse cave systems in the world, with 21 km of passages, galleries and magnificent halls, which offer an unparalleled experience of the underground world and a large diversity of underground animals – including the world-famous human fish (proteus anguinus).  

After Postojna Cave we round up the trip by visiting Predjama castle, built into a high cliff; the most remarkable castle in Slovenia. It is an interesting and romantic sight throughout the year: in the spring and summer its surroundings are abundant with blossoms and flowers, in the autumn it is clad in the colours of surrounding forests and it is at its most enchanting in the winter when the surrounding area is covered in snow.  

In the afternoon we drive towards Ljubljana, a vibrant capital full of interesting places to go and things to do. You can enjoy a visit to Ljubljana Castle, take a boat trip on Ljubljanica river, visit galleries and museums or you can simply enjoy drinking a cup of coffee or a glass of beer in one of many cute bars by the river.
