Further north in Pacific Palisades one finds the beaches used in the television series Baywatch. The fabled Malibu, home of many a film or television star, lies west of it.

In the mountain, canyon, and desert areas one may find Vasquez Rocks Natural Area Park, where many old Westerns were filmed.

Rail

Los Angeles is a major freight railroad transportation center, largely due to the large volumes of freight moving in and out of the county's port facilities. The ports are connected to the downtown rail yards and to the main lines of Union Pacific and Burlington Northern Santa Fe headed east via a grade-separated, freight rail corridor known as the Alameda Corridor.

Passenger rail service is provided in the county by Amtrak, Los Angeles Metro Rail and Metrolink.

Amtrak has the following intercity Amtrak service at Union Station in the city of Los Angeles.

Union Station is also the primary hub for Metrolink commuter rail, which serves much of the Greater Los Angeles Area.

Light rail, subway (heavy rail), and long-distance bus service are all provided by the Los Angeles County Metropolitan Transportation Authority (Metro).

Sea

The county's two main seaports are the Port of Los Angeles and the Port of Long Beach. Together they handle over a quarter of all container traffic entering the United States, making the complex the largest and most important port in the country, and the third-largest port in the world by shipping volume.

The Port of Los Angeles is the largest cruise ship center on the West Coast, handling more than 1 million passengers annually.

The Port of Long Beach is home to the Sea Launch program, which uses a floating launch platform to insert payloads into orbits that would be difficult to attain from existing land-based launch sites.

Ferries link the Catalina Island city of Avalon to the mainland.
