EBMUD’s Pereira Road Trailhead provides access to over 10 miles of trails as well as a back entrance into John Muir Land Trust’s Fernandez Ranch and a connector to EBRP”s Sobrante Ridge Regional Preserve. The trails are mostly on historic ranch roads, some very steep, climbing over 400 feet through rangeland and oak woodlands, from Alhambra Valley Rd to the top of the northern ridge, to provide sweeping views from Mt. Diablo to the distant Solano hills, across the Carquinez Strait.*2

This scenic hike takes you along the trails in EBMUD’s Pinole Valley Watershed areas and into the parkland at John Muir Trust’s Fernandez Ranch. The return includes a fabulous stretch along the Bay Area Ridge Trail with panoramic views of the surrounding hills and ridges from Mt Diablo and across San Pablo Bay and beyond!
