Dockweiler State Beach features a three mile long shoreline with a picnic area and concession stand. The wide beach is beneath the takeoff path from Los Angeles International Airport. Although this is a State Beach, there are no camping sites that are reserved through ReserveAmerica. The park is operated by a local agency.
This beach ride can't be beat, there is an established bike path the whole way, and we didn't have to wrestle with cars or too many pedestrians. It's easy to lose track of how long the ride is when the ocean is right alongside you the entire way.
You will need a bicycle to fully enjoy this path. Yes, often you'll see pedestrians but they should be paying attention to the 'bikes only' markings posted everywhere. It has amazing ocean views and should be completed at least once. Avoid the summer months if you don't want to constantly dodge tourists.
