“One of the few legal single tracks on Mt. Diablo
— Mike Anciaux
The Diablo Ranch Trail is one of the few legal singletrack trails in Mt. Diablo State Park. It is a windy, up and down trail that is generally covered in a bit of loose gravel.
You can do the trail in either direction. From the top, access Diablo Ranch Road from Angel Kerley Rd
. From the bottom, start at the parking lot just across from Diablo Ranch.
