Cabeza Prieta National Wildlife Refuge Review

The 860,000-acre Cabeza Prieta National Wildlife Refuge, about 10 minutes from Ajo, was established in 1939 as a preserve for endangered bighorn sheep and other Sonoran Desert wildlife. A free permit, essentially a "hold-harmless" agreement, is required to enter, and only those with four-wheel-drive, high-clearance vehicles, or all-terrain vehicles—needed to traverse the rugged terrain—can obtain one from the refuge's visitor center.
