Pine Lake Park, Urban park in San Francisco, US

Pine Lake Park is an urban park in San Francisco centered on a freshwater lake surrounded by walking paths and natural vegetation. The water lies in the city's western section and is framed by several paths that wind through the surrounding landscape.

The Greene family, who moved from Maine to San Francisco in 1847, owned the land that includes today's park and lake; a lawsuit in 1887 left them only this portion, and they planted the eucalyptus trees around the water. The City of San Francisco bought the land and lake within five years of the adjoining Sigmund Stern Recreation Grove opening in 1932.

The lake and its eucalyptus trees trace back to the Greene family, who moved from Maine in 1847 and kept this parcel after an 1887 lawsuit. The trees they planted still ring the water. The park is also a stop on the Pacific Flyway, where migratory birds feed and rest.

A trail circles the lake and links to a wider path network through Stern Grove and a stretch of the Bay Area Ridge Trail. The park is open all year from 6am to 10pm and has a dog play area. It sits in the southwest corner of San Francisco, next to Sigmund Stern Recreation Grove.

The lake attracts numerous bird species and provides habitat for diverse wildlife in the middle of the city. This makes the spot a surprising oasis for nature observers looking to spot uncommon birds.
