Shirttail Canyon

Features great swimming hole below suspension bridge.

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.

First half is a twisting paved road, narrow in spots. Watch for bikers. Second half is an easy dirt road. Four-wheel drive recommended.
