Geography
Poltarica Spring—the source of Poltarica Creek, a tributary of the Krka River—lies southwest of the village core. Above the spring is Poltarica Cave, which was discovered in April, 2003. The cave has been explored to a length of 740 m and contains passages, halls, canyons, and siphons. A population of olms lives in the cave, and during high-water conditions there is also a subterranean waterfall in the cave.
