“Winding dirt doubletrack that will zip you through the forest. Great jumps and views of Groveland!”

This dirt doubletrack is forest service road 1S33. It is a winding dirt road that will zig zag you on the side of the ridge of the mountain. It starts at the trailhead and links up with the ridge trail.

Combine this with the Ridge Trail - you can either ride this west to the Ridge Trail and take that trail back to complete the loop, or start with the Ridge Trail and use this moderate grade road to ride back to the trailhead.
