The pint-sized aquarium at the end of the Manhattan Beach Pier hosts this free, family-friendly festival full of educational, Earth-loving activities (with a distinctly marine angle). Bring binoculars to scan the sea for dolphins and wildlife, watch plankton races and fish feedings, and listen to talks about sharks and ocean conservation. You’ll also find crafts, games and face painting.
