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

Sulphur Springs Valley still retains large expanses of desert grasslands that conservation scientists have identified as a 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 The National Park Service’s Fort Bowie National Historic Site and The Bureau of Land Management’s Bowie Mountains scenic area of environmental concern. It is also the historic homelands of the Chiricahua Apache, who produced such leaders as Cochise and Geronimo.
