Postojna Cave and its exciting interior will take you on a fantastic journey beneath the surface of the Earth. Thus, it is no wonder that it has, during the 200 years since it was opened to the public, hosted over 36 million visitors from all over the world. A fantastic web of tunnels, passages, galleries and halls, the astonishing diversity of Karst features as well as easy access are certainly the main reasons for such popularity of the cave.
Postojna Cave is a network of 20 kilometres of passages, galleries and chambers into which experienced guides have accompanied more than 35 million visitors in the last 188 years. It is the largest cave in the “classic karst” and the most vis¬ited show cave in Europe. In 1872 railway lines were laid in the cave; electricity arrived in 1884. Today you begin your visit aboard the cave train; the electric lighting allows you to admire the size and splendour of the underground world, where the geological past is recorded in a unique manner. Visitors to the cave are dazzled by a wealth of speleothems: calcite formations, stalactites and stalagmites abounding in a variety of shapes, colours and age. The constant temperatureinthe caves ranges from 8 to 10° C. A guided visit lasts an hour and a half. Audioguides are available in 15 languages (Slovene, English, Croation, German, Italian, Spanish, French, Polish, Hungarian, Czech, Russian, Hebrew, Japanese, Korean and Chinese language /Mandarin/).Take the train through the underground world of the largest cave in the Classic Karst and the most visited tourist cave in Europe to see magnificent caverns and glistening stalactite formations. View the largest collection of cave animals in one place. The nearby Pivka and Črna jama caves are also worth a visit.
Between May and October, cave tours are held every hour, and in the off season three to four times daily. Tours take about an hour and a half, which gives you a perfect opportunity to see other sights within the Postojna Cave Park during the rest of the day.
