Chapman Drive is a 2.6-mile ascent from the Boulder Canyon trailhead to Realization Point. This is an excellent trail and an adventure with your dog. Along the way, there are several historic rock walls and structures to see. The trail was built in 1935 by the Civilian Conservation Corps (CCC), who also built Chapman Drive to connect Flagstaff Road and Boulder Canyon. Visitors can also take Tenderfoot Trail before arriving at Realization Point to add a few more miles to their journey. Hike, bike, or run this broad gravel path in and out of the shade.
