Planina Cave, Underground cave system in Inner Carniola, Slovenia
The cave extends 6,656 meters beneath limestone cliffs, featuring two underground rivers that merge to form the Unica River system.
The cave, previously named Little Castle Cave, connects to the Postojna Cave system, forming a network of over 31 kilometers of passages.
Scientists conduct research in the cave to study its population of olms, rare amphibians adapted to life in complete darkness.
The temperature inside remains at 9 degrees Celsius, requiring visitors to wear warm clothing and sturdy shoes during guided tours.
The underground confluence of Pivka and Rak rivers forms one of the largest subterranean river junctions in Europe.
