The Postojna Cave is complex of 20 kilometres of tunnels filled with stalactites, galleries and halls, into which experienced guides have led more than 31 million visitors during the 185 years. This is the biggest cave in classic Karst, and at the same time, the most visited tourist cave in Europe. The most interesting tunnels were idiscovered n 1818 by Luka Čeč and the locals opened the cave for tourist visits the following year. In 1872 railway tracks were laid in the cave, and in 1884, electrical wiring was installed. The Postojna Cave is the only cave in the world operating a cave train, so visitors can admire the immensity and the powerful allure of the underground world, where the geological past is revealed to visitors in its own way while riding a train. Their gazes are filled with the innumerable richness of stalactites of various shapes, colours and generations, calcareous sinters and other works of art which nature developed over millennia, and which had been admired in the previous centuries by kings, caesars, presidents of countries and other important people. Since the middle of 17th century, the Postojna Cave has been a point of interest for natural scientists and explorers, and thus it is also known as the cradle of speleobiology, the science of life in the underworld.
The Postojna Cave is open throughout the year, visits lasts for an hour and a half. The constant temperature in the cave is about 10°C.
Besides visiting the Postojna Cave, you can also join the organised tourist visits of other caves in the Postojna Cave system: Pivka Cave, Black Cave, Planina Cave, Otok Cave and the Cave under the Predjama Castle.
