Boston, United States of America
The Swan Boats are a fleet of pontoon pleasure boats which operate in a pond in the Public Garden in Boston, Massachusetts. The Swan Boats have been in operation since 1877, and have since become a cultural icon for the city. They operate from the second weekend of April to the weekend of Labor Day.
