Pivska površ (Cyrillic: Пивска површ), is a high limestone plateau in the drainage area of Piva, between the mountains of Durmitor, Maglić, Lebršnik, Golija and Vojnik. The plateau is 55 km long, 30 km wide with an average altitude of 1.200 m, the highest 2.159 m. The flow of Komarnica-Piva divides it in two regions: western one, Pivska Župa (Cyrillic: Пивска Жупа) and eastern one, Pivska planina (Cyrillic: Пивска планина). Area is characterized by many limestone features, like cavities (called vrtača, вртача) deep pits and excavations, and extremely sparsely populated (some 20 smaller settlements in Pivska Župa and 15 in Pivska planina).
