I have been there. The Rockford Files were filmed at Paradise Cove. Rockford's trailer was on the beach. Now the so called "stars" will not let anyone walk on the beach near Paradise Cove. As far as I know, it is against the law for rich movie actors and others to steal public beaches in California. They have made it off limits. They are destroying the environment in that place.
Do you live here? Paradise Cove beach is fully accessible and available to the public.
There are miles of public beach in Malibu, and I have enjoyed a few of them:
