Ruby Road runs through the Coronado National Forest from the Pena Blanca Lake Recreation Area to near the tiny hamlet of Arivaca. The wide, well-maintained road winds through the Atascosa Mountain Range and its foothills. The hilly landscape on the eastern slopes is dominated by grasslands dotted with oak trees. The western slopes are forested with mesquite trees and cacti. The Ruby ghost town sits midway along the route.
There are several campsites along the trail. The best is at Bear Valley, just east of the one-lane bridge that crosses Arroyo Los Alisos. The shaded site has a fire ring and enough level ground for four to five vehicles. It is suitable for tent camping along the way. Other campsites sit along the many spurs off the trail.
