The reopened Annenberg Community Beach House is a great place for families to relax and play. Originally built in the '20s for Marion Davies, actress and mistress of William Hearst, this mansion was a hot spot for A-list celebs until its recent renovation into a public beach house. This attraction, which opened in 2009, offers a pool (open 10am-6pm in summer), guesthouse facilities, recreation and family fitness classes, a gym, docent tours, volleyball and tennis courts (available upon reservation), beach rentals (chairs, balls, boogie boards, and so on), a nice cafe, and access to the wide beaches of Santa Monica.
