Beaches and parks
Ocean Beach runs along the Pacific Ocean shoreline, but is not suitable for swimming because the waters off the coast are cold and have deadly rip currents. Baker Beach occupies a picturesque setting just west of the Golden Gate Bridge and is where one of the only existing colonies of Hesperolinon congestum, the threatened Marin Dwarf Flax, can be found. The biggest and most well-known park is Golden Gate Park, stretching from the center of the city to the Pacific Ocean. Once covered only in grass and sand dunes, the park is planted with thousands of non-native trees and plants and is rich with attractions including the Conservatory of Flowers, the Japanese Tea Garden, and Strybing Arboretum. The Presidio, a former military base, and its Crissy Field section, restored to its natural salt marsh condition, are part of the Golden Gate National Recreation Area, which includes Alcatraz, and other regional parks. Buena Vista Park is the city's oldest, established in 1867. Lake Merced is a fresh-water lake surrounded by parkland.
