Auto Tours

Ajo Mountain Drive (21 miles): Winds along the foothills of the Ajo Mountains, the highest range in the area. Outstanding desert landscapes and impressive stands of organ pipe cactus are among the highlights of this tour. It also includes a spectacular view of a natural stone arch in Arch Canyon. The drive takes about two hours; the road, which twists and dips, is mostly gravel and is passable by normal passenger cars. RVs over 24 feet are not advised to travel this route. There is a free guidebook to this drive available at the Visitor Center. This is a popular biking route, please be aware and courteous to bikers.

Puerto Blanco Drive (37 miles): The first five miles allow 2-way traffic on the north end of the loop, providing access to the Pinkley Peak Picnic Area. Several stops along the way provide wonderful views and information on the ecology and culture of the Sonoran Desert. The drive was reopened completely in 2014. High clearance vehicles recommended after Pinkley Peak.

Ajo Mountain Drive

Besides these two roads, there are the Bates Well Road, Pozo Nuevo Road and Camino de Dos Republicas. These roads are more rugged and high clearance or 4x4 vehicles are advised. See historic sites with windmills, ranch houses, abandoned gold and silver mines, and other remnants of the past. Be aware and comply with any caution signs you may see. Check on road conditions at the visitor center before you go.

When auto touring, carry emergency tools; take drinking water and extra water for your vehicle; stay away from flooded areas; and never drive off the road. Ramadas and picnic areas are located in scenic spots on both drives.

Biking

Biking is allowed on all roads open to vehicular traffic. Bikes are not permitted on trails.
