Golden Gate Park, located in San Francisco, California, United States, is a large urban park consisting of 1,017 acres (412 ha) of public grounds. It is administered by the San Francisco Recreation & Parks Department, which began in 1871 to oversee the development of Golden Gate Park. Configured as a rectangle, it is similar in shape to but 20 percent larger than Central Park in New York City, to which it is often compared. It is over three miles (4.8 km) long east to west, and about half a mile (0.8 km) north to south. With 24 million visitors annually, Golden Gate is the third most-visited city park in the United States after Central Park and the Lincoln Memorial.

The Golden Gate National Recreation Area (GGNRA) is a U.S. National Recreation Area protecting 82,027 acres (33,195 ha) of ecologically and historically significant landscapes surrounding the San Francisco Bay Area. Much of the park is land formerly used by the United States Army. GGNRA is managed by the National Park Service and is the most visited unit of the National Park system in the United States, with more than 15 million visitors a year. It is also one of the largest urban parks in the world, with a size two-and-a-half times that of the consolidated city and county of San Francisco.

The California Coastal National Monument is located along the entire coastline of the U.S. state of California. This monument ensures the protection of all islets, reefs and rock outcroppings along the coast of California within 12 nautical miles (22 km) of shore along the entire 840-mile (1,350 km) long coastline. Conservative estimates are for at least 20,000 such outcroppings. The monument was created by Bill Clinton via Presidential proclamation on January 11, 2000, with the authority in section two of the Antiquities Act of 1906. As of 2014, the monument has expanded to 2,272 acres (919 ha). The U.S. Bureau of Land Management, an agency of the U.S. Department of the Interior that manages the monument, has developed gateways in cooperation with other agencies along the California coast to introduce the monument to the public. These include the Trinidad, Point Arena, Fort Bragg-Mendocino, Pigeon Point Lighthouse, Piedras Blancas State Marine Reserve and Marine Conservation Area, and the Palos Verdes Peninsula. Although being the most-viewed national monument in California, people are usually unaware that the entire coastline is a national monument.
