Description
Beginning in Shell Ridge Open Space, the Four Days Diablo Trail is a challenging backpacking adventure that connects multiple parks and open space preserves on its journey toward Mount Diablo. The route traverses rolling grasslands, oak woodlands, scenic ridgelines, and remote backcountry landscapes, offering sweeping views of Mount Diablo and the surrounding East Bay hills.
This 30.7-mile point-to-point trek features 5,767 feet of elevation gain, making it one of the region's premier multi-day hiking experiences. Most hikers complete the route over three days and two nights, camping at designated backcountry campsites along the way while exploring one of the Bay Area's most scenic trail networks.
