San Francisco Bay Discovery Site, Historical memorial on Sweeney Ridge in Pacifica, US
The San Francisco Bay Discovery Site features a commemorative marker at the summit of Sweeney Ridge, offering expansive views of the surrounding coastline.
Captain Gaspar de Portola and his expedition party first spotted San Francisco Bay from this location on November 4, 1769, during their search for Monterey Bay.
The Ramaytush Ohlone people, who inhabited the San Francisco Peninsula with approximately 2,000 members, guided the Spanish explorers to this ridge location.
Visitors can reach the memorial by following the Sweeney Ridge Trail from Fassler Avenue, which connects to Highway 1 in Pacifica.
Two permanent monuments stand at this National Historic Landmark, with the first installation occurring in 1975 and the second following in 1983.
