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. 

Much of the southern half of Hood Mountain burned in the 2017 wildfire. While significant regrowth has occurred, fire scars are abundant and several trails remain closed. Please see the Hood Mountain map for details. 


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.
