Manhattan Beach is a charming seaside resort town. On the beaches you have volleyball, surfing, and diving (apparently, this beach is a good spot to scuba dive from). The Manhattan Beach pier is a great place to walk around. There are no shops on this little pier, but at the end of it is Roundhouse Aquarium. The Strand through Manhattan Beach is a great place to hang out and enjoy the surf and sand.
The Roundhouse aquarium has a huge Shark Tank (with slithering moray eels and a giant black sea bass), a Touch Tank (with tide pool animals common to Southern California), a Lobster Tank (and other various crustaceans), Surge Tank (to demonstrate tides), Reef Tank and Tropical Aquarium (with brightly colored, non-native fish). It's definitely worth visiting!
