Cienega ranch is located near Willcox, Arizona on the south end of Sulphur Springs Valley between the Chiricahua and Dos Cabezas Mountains.

This valley still retains large expanses of desert grasslands that conservation scientists have identified as high priority for protection and restoration. The ranch sits in the middle of the Sky Island Region of Arizona, New Mexico, and northern Mexico, a keystone location for maintaining migration corridors and enabling populations of native species to stay connected. The ranch also protects and buffers adjacent public lands that are essential for preserving the ecology and history of Arizona, including National Park Service’s Fort Bowie National Historic Site and Bureau of Land Management’s Bowie Mountains scenic area of environmental concern. These surrounding lands are the homelands of the Chiricahua Apache, with well-known leaders like Cochise and Geronimo.
