Hiking
The China Hole and Middle Ridge Loop offers a quintessential Henry W. Coe State Park experience, blending diverse terrain with significant elevation changes. You'll traverse everything from shaded woodlands to open chaparral and grasslands, with the highlight being the challenging ascent to Middle Ridge for sweeping panoramic views. The trail's namesake, China Hole, provides a welcome natural swimming spot along the Middle Fork of Coyote Creek, making this a difficult 10.5-mile (16.8 km) hike with 1940 feet (591 metres) of gain that takes about 5 hours and 10 minutes.
Planning your trip requires careful consideration; there's no potable water beyond the Coe Ranch Entrance, so pack enough for the entire route. Creek crossings can be tricky or impassable after heavy rains, and summer heat can be intense, making spring or fall ideal. Be aware of the park entrance fee, and note that dogs are not permitted on the trails.
Henry W. Coe State Park is California's second-largest state park, and this loop showcases its wild, untamed character. Beyond the stunning vistas from Middle Ridge, you'll pass through varied ecosystems, spot seasonal wildflowers, and get a glimpse of the historic Madrone Soda Springs resort site. It's a rewarding adventure for those seeking a true wilderness feel close to the Bay Area.
