Grandview Park, also referred to 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.
Despite its small size, 3.98 acres or about the size of a city block, the park is important geologically and botanically and offers views of downtown San Francisco, Golden Gate Park, to the Pacific Ocean, the Marin headlands, and across to the Sutro Tower.
The summit of Grandview Park rises to about 666 feet. 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.
