1 Best Sight in Cape Cod, Massachusetts

Woods Hole Science Aquarium

Fodor's choice

This impressive facility displays numerous large tanks and many more smaller ones filled with regional fish and shellfish. Rooms are small, but they are crammed with stuff to see. Magnifying glasses and a dissecting scope help you examine marine life. Several hands-on pools hold banded lobsters, crabs, snails, starfish, and other creatures. The stars of the show are two harbor seals, on view in the outdoor pool near the entrance; watch their feedings, most days, at 11 and 4.
