Introducing Postojna
The karst cave at Postojna, one of the largest in the world, is among Slovenia’s most popular attractions. As a result, it is very commercialised and jammed most of the year with tour groups. It must be said, however, that Postojna’s stalagmite and stalactite formations are unequalled.

The Postojna Cave (Postojnska Jama) system, a series of caverns, halls and passages some 20.5km long and two million years old, was hollowed out by the Pivka River, which enters a subterranean tunnel near the cave’s entrance. The river continues its deep passage underground, carving out several series of caves, and emerges again as the Unica River. The Unica meanders through a sunken field of porous limestone – the Planinsko Polje (Planina Polje) – which becomes Lake Planina in the rainy season. But, as is the nature of what is called a ponor river, it is soon lost to the underground. It reappears near Vrhnika as the Ljubljanica River and continues its journey northward to the capital.
