Boston Duck Tours offer visitors a novel way to see the city. Amphibious World War II landing craft tour the historic sites, with well-informed con”duck”tors providing an entertaining commentary throughout the eighty-minute trip. The trip is mainly on roads, but for about twenty minutes the boat takes to the water offering spectacular views of the city skyline from the Charles River. While afloat, the young, and young at heart, are offered the opportunity to take the controls.
