This little aquarium is located at the end of the Manhattan Beach Pier and may be fun to stop in if you're already at the pier. Otherwise, it doesn't warrant a special trip. This free (donations suggested) aquarium is a small facility with a few tanks containing ocean critters native to the area. We particularly liked the ray and shark tank. On Saturday afternoons there is story time for kids. Also, it may be fun to watch people go fishing off the pier.
