Niagara Falls is a group of three waterfalls located at the southern end of the Niagara Gorge. The site spans the international border between the Canadian province of Ontario and the U.S. state of New York.
The largest of the three falls is Horseshoe Falls, which straddles the border between Canada and the United States and is also known as the Canadian Falls. The two smaller waterfalls, American Falls and Bridal Veil Falls, are located entirely within the United States.
