The trail begins 1/4 mile from Highway 4 at the Spicer Reservoir Road parking area. The trail descends gradually approximately 2.5 miles to the Stanislaus River, where it crosses a bridge then ascends quickly out of the canyon. From this point, the trail offers a gentle, level ride to a 3-way intersection, 8 miles from the parking lot. Riders may continue on to Union and Utica Reservoirs, Summit and Elephant Rock Lakes, or the Spicer Reservoir Power House. Very experienced riders may continue on the un-groomed route along Slick Rock Road to access Lake Alpine.
