National Marine Aquarium
This excellent aquarium—the U.K.'s largest—on the town's harbor presents aqueous environments, from a freshwater stream to the Great Barrier Reef and the Biozone. Don't miss the chance to walk beneath sharks in the Atlantic Ocean tank, alongside clownfish, angelfish, and cleaner wrasses in the Biozone. Feeding times are fun for the kids, and Waves Café, with its harbor views, makes a good spot for a rest and refreshment. Tickets, which are valid for one year, should be booked ahead at peak times.
