**Gunung Sewu** (Thousand mountains)[1] is the name for the [karst](/source/Karst) region of southern central [Java](/source/Java) that lies to the south east of [Yogyakarta](/source/Yogyakarta), south of [Surakarta](/source/Surakarta), and is considered a very dry and poor socio-economical region in Java. It has poor rainfall compared to the volcanic mountain areas to the north and east. Administratively most of the region is part of [Gunung Kidul Regency](/source/Gunung_Kidul_Regency), within the [Yogyakarta](/source/Yogyakarta) province besides [Wonogiri Regency](/source/Wonogiri_Regency) and [Pacitan Regency](/source/Pacitan_Regency). In 1993, the world [speleologs](/source/Speleology) proposed Sewu Mountains Karst Area as a world heritage. And on December 6, 2004 Sewu Mountains and South Gombong have been announced as eco-karst.[2]

It is a region where archaeological evidence shows very early human activity [3]

It is very popular with cavers.[4][5] There are 119 caves below of about 40,000 karst cone hills in 13,000 square kilometer area.[2] The only [cave-adapted](/source/Troglobite) crab from Java, *[Sesarmoides jacobsoni](https://en.wikipedia.org/w/index.php?title=Sesarmoides_jacobsoni&action=edit&redlink=1)* ([Sesarmidae](/source/Sesarmidae)), is [endemic](/source/Endemism) to the Gunung Sewu cave system.
