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. Explore the magnificent Predjama Castle perched high up in a vertical cliff.

Visit two of Slovenia's top attractions on this half-day small-group tour from Ljubljana.

The number of participants is limited to eight to ensure a personalized experience.

Postojna Cave is the most famous cave in the world. It is also the biggest tourist attraction in Slovenia and one of the largest karst monuments in the world, a must-see when visiting Slovenia. Enjoy the tour with a unique and adventurous ride in a special train in one of the most diverse cave systems in the world, with 21 km of corridors, an ethereal network of stalactites, stalagmites, and caverns, galleries, and magnificent halls that offer an unparalleled experience of the underground world and a great variety of underground animals - including the world-famous human fish (Proteus anguinus).

In addition to Postojna Cave, you will also have the opportunity to visit Predjama Castle. We will show you this magnificent medieval castle perched high on a vertical cliff in the idyllic village of Predjama. Explore the chambers and staircases and learn about the castle's most famous resident, Erazem of Predjama. The castle is an interesting and romantic sight all year round: in spring and summer the surroundings are rich in blossoms and flowers, in autumn it is wrapped in the colors of the surrounding forests, and in winter when the surroundings are covered with snow, it is at its most enchanting.
