There's no track, so I wasn't sure where to go. I found a few markers for the Chabot to Garin Trail, but the tunnel was flooded from the rain and heading south I couldn't follow the trail. Then I saw some bikers coming down Cull Canyon Road, so I'm assuming the track is to take Cull Canyon until it ends then come back to the parking lot, which is about 11-12 miles. It was a pay up, play down ride, with some local traffic to contend with. I saw some deer and a group of pigs cross the road. A couple of the drivers were flying, so be careful. The posted speed limit is 30.
