Is there any way to gain access to the beach along Malibu Colony in Malibu, CA?

Answer 1

Sure.... there is public access. California law prohibits removal of public access to a beach. Here's a site that answers your questions listed below.

From site:
Residents of the Colony naturally value their privacy, and don't want visitors on "their" beach. The fact is, however, that it's a public beach (at least below the high-tide line), so it's our beach too, and coastal access laws require that the public be allowed access to that public portion of it. The trick is getting to the public part of the beach.
