Spend a night on Southern California's sandy shore with the Cabrillo Marine Aquarium! This 4-pack of tickets gives you access to San Pedro's Cabrillo Beach for an evening "meet the grunion" program during the world-famous "grunion run." Grunion are small sardine-size fish of the silversides family, which are among the few species of fish that actually come ashore to lay their eggs on sandy beaches. They are found from Southern California, all the way south to Baja California, and arrive at night after the high tide around the new moon and full moon. Cabrillo Beach is one of the best places to observe the fish, and Cabrillo Marine Aquarium hosts "meet the grunion" programs from March through July of each year.
