Seaside Aquarium is one of the oldest aquariums on the West Coast.  Founded in 1937, the aquarium is privately owned and the descendants of some of the founders are still active in the aquarium operation. The Aquarium is proud to be involved in public awareness programs: Marine Mammal Stranding Network, Seaside Beach and Estuary Discovery Program, Sea Week, and other marine education tours and activities for school children.
