Cabeza Prieta Wilderness
Encompassing nearly 93% of Cabeza Prieta National Wildlife Refuge, the Cabeza Prieta Wilderness Area is located north of Sonora, Mexico and west of the small town of Ajo in southwest Arizona. The Cabeza Prieta Wilderness adjoins Organ Pipe Cactus National Monument to the east, Mexico to the south, and the Barry M. Goldwater Range to the north and west.
Directions On the west side of the refuge, visitors with refuge permits may access the wilderness area from Interstate 8 by traveling south from Exit 30 (west of Wellton) or Exit 42 (east of Tacna, Arizona).
On the east side of the refuge, visitors with refuge permits can access the east side of the refuge by traveling west on Rasmussen Road in Ajo for approximately 5 miles to Charlie Bell Road. For travel along the historic Camino del Diablo, visitors may travel south from Darby Well Road (located south of Ajo) to Bates Well Road, through Organ Pipe Cactus National Monument onto the refuge.
Note: While on Organ Pipe Cactus National Monument, the refuge permit is only valid for traveling through the Monument along Bates Well Road, not for recreational activities on Organ Pipe Cactus National Monument. A self-issue permit may be obtained at the Organ Pipe National Monument northern boundary for recreation on the National Park Service lands.
