Shirttail Canyon

Trail Overview

The main attraction of this route is a popular swimming hole below Colfax-Foresthill Suspension Bridge. Our round-about way of getting there follows a paved road through historic Iowa Hill, then continues on a narrow, winding dirt road through the forest. Take a picnic lunch and inner tube to enjoy the crystal-clear water of the American River inside Auburn State Recreation Area (fee area). Street-legal vehicles only. To go direct to swimming hole, use reverse directions.

History

Gold was first discovered in Iowa Hill in 1853 and mining continued off and on into the 1930s. A few mines have been intermittently worked in recent years. Most mining has been hydraulic, scars of which you'll see along the route. One spot along Iowa Hill Road has sheer cliffs on each side of the road due to hydraulic undercutting.
