Heal the Bay Aquarium
Run by beach conservation group Heal the Bay, this live marine-life menagerie contains more than 100 species of marine animals and plants, all found in Santa Monica Bay. The Dorothy Green Room features live and interactive exhibits about local watersheds and shark feedings and short educational films on the weekends. The Kid's Corner provides books, games, and a puppet show. Don't miss this chance to learn about the area's ecology and the staggering evidence of how pollution is affecting ocean life. The aquarium can be tricky to find—look for it tucked under the eastern end of the Santa Monica Pier bridge along Ocean Front Walk. Follow the colorful seascape murals that cover the outside walls. Free admission for kids ages 3 and under.
