San Bruno Mountain is a fault-block horst in northern San Mateo County, California; its northern slopes rise in San Francisco. It is surrounded by San Francisco Bay and the cities of Brisbane, Colma, Daly City, and South San Francisco, and has played an important role in the history of all these communities.
Topped by a four mile long ridge, trails along the summit afford expansive views of the San Francisco Bay Area. Much of the mountain is in the 2,326-acre San Bruno Mountain State Park or the adjoining 83-acre State Ecological Reserve. Radio Peak, the highest point, serves the hilly Bay Area with several radio/TV broadcast towers.
