Henry W. Coe State Park

Henry W. Coe State Park spans over 87,000 acres of rugged terrain east of Silicon Valley, making it the largest state park in Northern California. The park features rolling hills, steep canyons, oak woodlands, chaparral, and riparian habitats, supporting a rich variety of wildlife including tule elk, mountain lions, bobcats, and numerous bird species. The park’s geography is dominated by hilly landscapes shaped by streams and springs, with elevations ranging from approximately 600 to 3,600 feet. Historically, the land was once used for ranching and mining before being designated a state park in the mid-20th century and later renamed in honor of Henry W. Coe, a prominent advocate for California’s parks. Today, the park is prized for its remote and challenging backcountry experience, with over 250 miles of multi-use trails for hiking, mountain biking, and horseback riding. Key recreation opportunities include backpacking adventures with numerous designated campsites, day hikes to scenic views like Deerhorn Ridge and Blue Ridge, and fishing in the park's seasonal streams and reservoirs. Notable landmarks include the summit of Mount Sizer, named after a former park ranger, which offers panoramic views of the Diablo Range. The park attracts outdoor enthusiasts seeking solitude, challenging terrain, and diverse natural habitats within a relatively close drive from the Bay Area. Its extensive trail system and rugged wilderness make it ideal for advanced hikers and riders who appreciate less-crowded outdoor spaces.
