Splitting the park in a general north-south to southwest direction with a developed trailhead at each end, this trail is acts as a backbone for the trail system. Along with the park, it is named after the original ranching family that settled this area in 1829.
From the north end, it is a rough road with some roots and rocks to the junction with the Spengler Trail
. Pass through the gate and veer to the right as the road rises gradually toward Briones Peak to the junction with Briones Crest Trail
. At the crest be sure to look back for a view of the Sacramento River Delta.
Pass through a gate to begin a fast winding descent into the Bear Creek valley. The road flattens at the junction with the Valley Trail near some corrals. The rest of the trail is flat but fast, with a gate or two to pass until you reach the Bear Creek Staging area.
