What makes the Postojna Cave so special?

The only cave with a double track railway
For 140 years, the Postojna Cave, as the only cave in the world, offers a unique and adventurous ride with a special train, which will take you into the cave, under spectacular underground arches, which are embellished with chandellier look-alike stalactites, through a beautiful subterranean world full of playful limestone sculptures.

Stalactite paradise on every corner
21 km of passages, galleries and magnificent halls offer a unique experience of the underground world. The Postojna cave is definitely one of the most diverse cave systems in the world.

Meet the dragon's offspring
The unusual looks of the olm have always sparked our imagination. At first it was believed that they were just baby dragons which the high tide brought to the surface. As a matter of fact, there might be some truth to these old beliefs.

Five-metre jewel
The most beautiful stalagmite in the Postojna cave is called the Brilliant. Looking at this marvellous, shiny white limestone formation, you simply must agree it is fully worthy of its name.

A tourist attraction for 200 years
In 1819 Archduke Ferdinand I visited the cave and became the first official visitor. This gave rise to the tourism in Postojna and this date is considered the official start of modern cave tourism although signatures dated from the 13th century can be found in the cave.

Anybody who wants to be somebody must visit
In its 200 year-old history, the cave has impressed over 35 million visitors from all over the world, many of which have left their signature in the memorable visitors' books.
