      This beautiful loop trail, which parallels Hwy 49 on one side and the American River Canyon on the other, passes through open, rolling hills with several species of oak trees, and wildflowers in spring. It also includes steep canyon descents and climbs as it crosses Knickerbocker and Salt Creeks. Side trails on the canyon side offer panoramic views of the North Fork American River and of the Auburn dam construction site. Trail markers have been posted about every half-mile and at most trail intersections
