"Sitting on the site of what was once a giant mansion that Randolph Hearst built for actress Marion Davies in the ’20s, this is now a 5-acre, completely public beach house, complete with the home’s original Olympic pool (the house was irreparably damaged by an earthquake, which led to its demolition). When it’s not pool season (Memorial Day through Labor Day), there’s still a lot to do, including a toes-in-sand cafe and beach volleyball for kids."
