RiverLink Ferry, Philadelphia

Just south of the Benjamin Franklin Bridge, the Delaware River bustles with activity. On its western shore lies Philadelphia's waterfront, with destinations such as Penn's Landing. To the east is Camden, which holds its own against the Pennsylvania capital with attractions such as Adventure Aquarium, where Aquaman moonlights as a jellyfish. But perhaps the area's biggest draw is the meeting place between these two locales: the Delaware River itself.

RiverLink Ferry's two-story sightseeing vessel, the M/V Freedom, traverses these waters for sightseeing tours of the waterfront's architecture or fall foliage. The ferry serves a practical purpose as well; it regularly travels point-to-point between Philadelphia and Camden, so commuters can move between the two cities with ease.
