Santa Monica & Venice, Los Angeles

If you ever get down this far, this is an awesome ride along the beach any time of the year. It does get a little busy in the summer but nothing unbearable.
This ride takes you along Santa Monica Beach, past the Santa Monica Pier and along Venice Beach.
Just did this in the past week and the Pacific Ocean looks amazing this time of year. If you don't have your own bike, there are several bike rental places all along the beach.
