The highest point in the city proper is Mount Lukens at 5,074 ft (1,547 m), located at the northeastern end of the San Fernando Valley.
The eastern end of the Santa Monica Mountains stretches from Downtown to the Pacific Ocean and separates the Los Angeles Basin from the San Fernando Valley.
Other hilly parts of Los Angeles include the Mt. Washington area north of Downtown, eastern parts such as Boyle Heights, the Crenshaw district around the Baldwin Hills, and the San Pedro district.

Surrounding the city are much higher mountains.
Immediately to the north lie the San Gabriel Mountains, which is a popular recreation area for Angelenos.

It was straightened and lined in 51 miles (82 km) of concrete by the Army Corps of Engineers to act as a flood control channel.
The river begins in the Canoga Park district of the city, flows east from the San Fernando Valley along the north edge of the Santa Monica Mountains, and turns south through the city center, flowing to its mouth in the Port of Long Beach at the Pacific Ocean.
The smaller Ballona Creek flows into the Santa Monica Bay at Playa del Rey.
