About Grandview Park

Grandview Park, is also known as Turtle Hill by local residents, is a small, elevated park in the Sunset District, San Francisco, California. It is surrounded by 14th and 15th Avenues, as well as Noriega Street. The summit of Turtle Hill rises to about 666 feet (203 m). It is an outcrop of chert, which is part of the heterogeneous assemblage known as the Franciscan Formation, or Franciscan Assemblage, the primary geologic feature on which the city of San Francisco is founded, here covered with a thin layer of sand. It provides one of the last remaining habitats within the city for a number of native plants, including the endangered Franciscan wallflower and dune tansy, and also bush lupin, beach strawberry, bush monkey flower, and coyote bush. The hill is crowned with Monterey cypress trees. Grandview Park on FoundSF.
