Planina Cave (Slovene: Planinska jama), formerly also Little Castle Cave (Malograjska jama) after Little Castle in the vicinity of its entrance, is one of the longest Slovenian active caves. It is a huge tunnel and the subterranean bed of the Unica River. It is located in Inner Carniola. Five hundred meters from the entrance into the cave is a confluence of two underground rivers: the Pivka River, flowing from the Postojna Polje through Postojna Cave, and the Rak River, flowing to Planina Cave through Weaver Cave from Rak Škocjan. This is one of the largest confluences of subterranean rivers in Europe.For travelers who use our world travel planner, Postojna holidays become easier to arrange, with trips to the Planina Cave and other attractions mapped out and timetabled.
Entrance into the cave is at the southwestern part of Planina Polje in the gable end valley below 65 high rocks. The length of the cave is 6,656 m (21,837 ft). It has been shown by water tracing that there is a connection between the systems of Planina Cave and Postojna Cave, and the administration of Postojna Cave estimates the connection will also be explored by cavers. The length of the joint system would be over 31 kilometres (19 mi).
Planina Cave reviews
Interesting cave with endemic life (we were lucky to see them), some facilities would be expected concerning the ticket you have to pay (not too expensive).

We took a 5 hour boat tour and our guide, Dejan, was excellent! He put a lot of effort into finding what we were interested in seeing so that we didn't miss anything. We had so much fun and will never forget this experience. Bear in mind that this tour requires good fitness and surefootedness (part of the trek is over slippery wet clay). Some basic experience with rowing is also necessary.
Beautiful water cave which houses Europe's largest convolution of underground rivers. Inside this cave, river Rak from Rakov Škocjan joins with river Pivka from Postojna cave and together they form river Unica which then flows across Planina field and disappeares underground again.
