New England Aquarium
Harbor seals love nothing more than fishsicles—dog toys and squid frozen together into blocks of ice—and a good water-spray massage from a hose. At Play with the Seals, go behind the scenes of their outdoor habitat, meant to simulate a rocky New England beach, with marine mammal trainers to help entertain the pups. Ages 9 and older; $45.
