The Rak is a stream in Inner Carniola, a traditional region of southeastern Slovenia. It sources in Zelše Caves (Zelške jame) west of the village of Zelše,[1] flows across the Rak Škocjankarst valley for 2 kilometres (1.2 mi) and enters Weaver's Cave (Slovene: Tkalca jama),[2] where it continues for 3 kilometres (1.9 mi) and merges in Planina Cave (Planinska jama), about 300 metres (980 ft) from its entrance, with the Pivka River to form the Unica.[3] The confluence of the Rak and the Pivka is one of the largest subterranean confluences in Europe.[4]
