Boston Harbor is a beautiful retreat from the city in any season. It is also the departure point for ferries to Cape Cod and the South Shore, whale watches and moonlit cruises. The history of the harbor has not been forgotten; the Boston Tea Party took place here and is recreated annually. The New England Aquarium is located on the water's edge. As you walk by, peek at the large tank to the left of the entrance—sometimes there are harbor seals living in it.
