The cave was first described in the 17th century by the pioneer of study of karst phenomena, Johann Weikhard von Valvasor, although graffiti inside dated to 1213 indicates a much longer history of use. In 1818, when the cave was being prepared for a visit by Francis I, the first Emperor of the Austria-Hungary, a new area of the cave was discovered accidentally by local Luka Čeč. In the 1850s, the Austrian-Czech geographer Adolf Schmidl published the first comprehensive scientific overview of the Postojna caves and the Pivka Basin, which became a standard reference point in the study of speleology.
Welcome to the world's most captivating cave with magnificent cave formations and diverse fauna. Take an unforgettable ride on Postojna Cave's underground train and experience a fascinating subterranean paradise shaped by tiny droplets over millions of years:
Please note, it is freezing cold inside with 10 °C or 50°F, so when you see the coats for rent at the cave entrance, and you think, “no, I can handle some cool air”, then think again, it is highly recommended. The cave is very impressive and there's a small train who will take you deep inside the cave (about four minute ride), where you will experience a near death freeze if you didn't take the coats.
The cave is located inside the Postojna Cave Park with another great attraction nearby - the Predjama Castle, check out their website for more information at https://www.postojnska-jama.eu/en
