This is the dirt portion of the trail from Briones Regional Park to Mt Diablo State Park. Most of the trail from Briones is on paved bike paths.
This portion starts in Shell Ridge Open Space (City of Walnut Creek, continues through Diablo Foothills Park (East Bay Regional Parks) and ends in Mt Diablo State Park (California State Parks).
This portion of the Briones to Mt Diablo trail is an easy ascent from Indian Hills School in Walnut Creek to the start of Wall Point Road
in Mt Diablo State Park. It is a well used and well marked fire road. Look for trail name indicators at each intersection. Most of the trail is through grassland so there is little shade in the summer. Watch for hawks and golden eagles that nest nearby.
This trail is a good starting point for a loop down Dusty Road and back Pine Canyon or a climb up Wall Point Road
