Park Closure

Due to impacts of the October 2017 wildfires, the Pythian Road entrance to Hood Mountain is closed indefinitely. 

The Los Alamos Road entrance reopened Jan. 20, with full access to trailheads at this entrance. Trails beyond the Hood Mountain summit are closed. 

Hood Mountain Regional Park & Preserve is a 1,750-acre wilderness park on the edge of the Sonoma Valley, about 5 miles southeast of Santa Rosa. The park offers 19 miles of trails for hikers, mountain bikers, and equestrians and features the only public backpacking sites in the valley. 

At 2,730 feet, Hood Mountain is the highest peak in the Mayacamas Mountains separating the Sonoma and Napa valleys. Its Gunsight Rock outcropping above Highway 12 offers stunning views of the valley and Bay Area landmarks beyond. 

Hood Mountain's features also include a pygmy forest, the headwaters of Santa Rosa Creek, and trail connections to Sugarloaf Ridge State Park. 


Environmental campsites are available in remote settings reached by hiking approximately 2 miles from Hood Mountain's parking areas. 


Hood Mountain offers the most extensive trail system within the Regional Parks system. Trails climb through mixed-conifer forests and cross meadows and several creeks, and the hiking can be strenuous.
