20.273 square kilometers and 8.800 registered caves... land of the original karst. Water was the most important creator of the karst geomorphology. Huge caverns, some with the length over 20 km, some like abysses with the depth of 1500 m, but all created by the subterranean water flow through the limestone or dolomite. Planinska jama (The Planina cave), one of the longest Slovenian water caves is a huge tunnel which is the subterranean bed of the Unica River. Five hundred meters from the entrance into the cave is a confluence of two underground rivers: Pivka River, which flows from Postojna polje through Postojna cave, and Rak River, which flows from Rakov Skocjan. This is the largest confluence of subterranean rivers in Europe. Entrance into the cave is on the southwestern part of Planina polje in the gable end valley below the 65 m high rocks. The length of the cave is 6.656 m. The temperature of the cave is constant and the contrast between the indoor and outdoor temperature is usually quite high - on the pano is easily visible a layer of haze- another form of the water.
