Cabeza Prieta Wilderness

Cabeza Prieta Wilderness has the distinction of being Arizona's largest Wilderness Area, encompassing nearly 93 percent of the Cabeza Prieta National Wildlife Refuge. The Wilderness spans across isolated and rugged, Sonoran desert landscapes including both the Arizona Uplands and Lower Colorado components which range from 700 to 2,800 feet. Rugged mountains and broad desert valleys, dotted with sand dunes and lava flows, dominate the region. This is a land of solitude, shattered only by the occasional summer monsoon or military overflight. To ensure you are aware of the dangers of unexploded military ordnance, a permit and your signature on a Holdharmless Agreement is required to enter the Wilderness.
