Sweeney Ridge is a hilly hiking area of ridges and ravines between San Bruno and Pacifica, about a 25-minute drive south from San Francisco. The ridge's 1,200-foot-high summit, covered with coastal scrub and grassland, slopes down to the bay on one side and to the Pacific on the other.
Wildlife at Sweeney Ridge includes hawks, deer, and a plethora of both native and introduced spring wildflowers. The sandy coastline and adjacent wind-protected valley of Thornton State Beach are good venues for picnicking, beach walking, surf fishing, and flying remote-control gliders. Take in views from this site, including the Farallon Islands, Mount Tamalpais, Point Reyes, Mount Diablo, the Montara Mountains, and San Pedro Point, that are directed by a nearby granite monument.
