The Monterey Bay Aquarium opened in Monterey, California, in 1984 and has become one of California’s best-beloved aquariums. Home to over 35,000 animals from more than 550 species (including fish, reptiles, birds, and invertebrates), there’s plenty to discover! Visitors can also take a guided tour, watch animal feedings, and watch documentaries in the aquarium’s auditorium. Book in advance to skip the lines and save money!
