South of Mammoth Lakes in the Inyo National Forest, the 8 mile one-way Rock Creek Trail is a local favorite, which can be ridden early season. The marked singletrack parallels Lower Rock Creek Road, the namesake creek gorge and US395, while rolling and twisting through forest. To reach mountain biking at the northern trailhead from Mammoth, head south on US395 for 15 miles. Just past Toms Place, turn right on Lower Rock Creek Road. After 100 yards, park on the right (trail starts across the road). The trail runs south and ends at Paradise Lodge.
Overall, Rock Creek Trail is the 85th most popular mountain bike trail of all 132 mountain biking rides in California.
