Ballona Creek is an 8.8-mile-long (14.2 km) waterway in southwestern Los Angeles County, California, whose watershed drains the Los Angeles basin, from the Santa Monica Mountains on the north, the Harbor Freeway (110) on the east, and the Baldwin Hills on the south. It heads in the historical Rancho Las Cienegas and flows through Culver City and the Del Rey district before emptying into Santa Monica Bay between the Marina del Rey and Playa del Rey districts.
Many national, historical, archeological and cultural landmarks, tourist attractions, educational institutions, businesses and industries exist in Ballona Creek Watershed. A bike path that extends almost seven miles from National Boulevard in Culver City to the end of Ballona Creek Estuary provides opportunities for recreation in the area. Ballona Creek Estuary and Ballona Wetlands provide habitat to many species of waterfowls, shorebirds, and waders.
