2 Best Sights in Ajo, Southern Arizona

This 860,000-acre national wildlife refuge, about 5 miles (a 10-minute drive) from Ajo, was established in 1939 as a preserve for endangered bighorn sheep and other Sonoran Desert wildlife, including the long-nosed bat and the Sonoran pronghorn deer, the fastest mammal in North America. People come here for hiking, photography, and primitive desert camping.

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.

Pick up a permit from the refuge's visitor center in Ajo, about a mile north of the downtown plaza.

You get an expansive view of Ajo's ugly gash of an open-pit mine, almost 2 miles wide, from the New Cornelia Open Pit Mine Lookout Point. Some of the abandoned equipment remains in the pit, and mining operations are diagrammed at the volunteer-run visitor center, where there's a 30-minute film about mining. The lookout point is always "open," but the visitor center's hours are sporadic. The mine is about a mile southwest of the plaza; take La Mina Road or Estrella Road to Indian Village Road.
