The Pythian Rd (South Entrance), Lawson Trail, and portions of the Lower Johnson Ridge Trail are now open.

Access via the Los Alamos Road entrance remains closed due to impacts of the 2020 Glass Fire. The closed area includes Hood Mountain Summit, Summit Trail, the Azalea Creek campground, and the Merganser Pond campground. Gunsight Rock can only be accessed via the Nattkemper Trail from the Goodspeed Trail in Sugarloaf Ridge State Park. See the park map for closure details.

Hood Mountain Regional Park & Preserve is a 2,000-acre wilderness park on the edge of the Sonoma Valley, about 5 miles southeast of Santa Rosa. The park offers more than 19 miles of trails for hikers, mountain bikers and equestrians. 

At 2,730 feet, Hood Mountain is the highest peak in the Mayacamas Mountains. Its Gunsight Rock outcropping above Highway 12 offers stunning views of the Sonoma Valley and beyond. 

The Lawson Trail allows the first public access to the recently acquired “Lawson Expansion” property, 247-acres on the western flank of Hood Mountain, overlooking eastern Santa Rosa in the western foothills of the Mayacamas, with views to the ocean and a meandering tour of Hood Mountain’s many diverse habitats. Learn more about this new trail.


Trails climb through mixed-conifer forests and cross meadows and creeks. Due to elevation gains, most of Hood's trails are considered moderately strenuous or strenuous.
