San Bruno Mountain State & County Park

Highlight • Natural Monument

San Bruno Mountain Park is located in northern San Mateo County, California, adjacent to the southern boundary of San Francisco and borders the cities of Brisbane, South San Francisco, Colma and Daly City -- a unique open-space island in the midst of the peninsula's urbanization at the northern end of the Santa Cruz Mountain Range. The Mountain's ridge line runs in an east-west configuration, with considerable slopes and elevations ranging from 250 feet to 1,314 feet at the summit. The 2,416 acres of rugged landscape offer excellent hiking opportunities and outstanding views of San Francisco and Central Bay Area. parks.smcgov.org/san-bruno-mountain-state-county-park

Brisbane Lagoon

Highlight • Lake

A remnant of San Francisco Bay, Brisbane Lagoon was formed by the construction of the U. S. Highway 101 causeway, and became diminished as most of its north and central portions were filled with landfill. Brisbane (/ˈbrɪzbeɪn/ BRIZ-bayn, unlike Brisbane, Australia) is a small city located in California in the northern part of San Mateo County on the lower slopes of San Bruno Mountain. It is located on the southern border of San Francisco, on the northeastern edge of South San Francisco, next to the San Francisco Bay and near the San Francisco International Airport. en.wikipedia.org/wiki/Brisbane,_California
