As with most things around Mystic, nautical themes abound at this interactive children’s museum 20 minutes down the coast in Niantic. Kids can set sail on a lobster boat and haul up traps with wriggly red plastic specimens, or descend to the ocean’s depths in a two-person submarine at the museum’s new seaside village exhibit. Areas for older kids allow them to experiment with magnets and shadow puppets. In addition to its exhibits, the museum also has several drop-off classes for toddlers and preschoolers in which they can learn to paint and make craft projects.
