R&R Travelers view Niagra Falls from the American Side.

The American Falls is the second largest of the three waterfalls that together are known as Niagara Falls on the Niagara River along the Canada-United States border. Unlike the much larger Horseshoe Falls, of which approximately 90% is in Ontario, Canada, and 10% in the U.S. state of New York,[2] the American Falls is entirely within the United States.
