Black Hills Rockhound Loop

The Black Hills rise from the Sonoran Desert like a fortress of volcanic rock and mining scars, where generations of prospectors left behind a maze of rough tracks connecting abandoned claims. This 18-mile loop winds through the heart of Arizona’s most accessible rockhounding district, passing the skeletal remains of the Black Rock Mine and threading narrow washes where flash floods carved channels through jasper-rich hillsides. The route climbs over Turquoise Ridge before dropping into Mineral Wash, where the old stamp mill ruins mark the halfway point.

This is moderate 4WD territory with rocky climbs, loose shale descents, and several tight switchbacks that’ll test your spotter skills. Stock high-clearance vehicles can handle most of it, but expect body damage from brush and rock contact. Best tackled October through April when desert temperatures won’t cook you. No permits needed on this BLM land, but bring plenty of water and expect zero cell service. The payoff is solitude, spectacular desert views, and some of the best agate hunting in the Southwest.
