Wonogiri Regency is an area of agriculture and plantation, so most of people in the regency work as farmers. Generally, all areas of the regency produce much agriculture and plantation output. Casava, cacao, and cashew are examples of the plantation output that are relatively good. Wonogiri also has many special foods. They include nasi tiwul, emping, bakso, mie ayam, gudangan, etc.^[4]

Most of Wonogiri Regency's area is rocky and hilly due to its location on the Sewu highlands. Since these highlands are of the karst type, many caves can easily be found in Wonogiri Regency and at least 41 caves have been discovered so far starting with the famous Song Gilap cave, Song Putri cave at Pracimantoro, Ngantap cave, Putri Kencana cave at Giritontro and including many unnamed caves all over the regency.

Wonogiri Regency also has a dam called Gajah Mungkur Dam which has three main functions; as a power plant to produce Hydroelectricity; to provide water for rice fields around Bengawan Solo River through irrigation programs; and for tourism.
