The waterfalls of Niagara Falls are located on the Niagara River in New York, which connects two of the five Great Lakes, Lake Erie and Lake Ontario, and serves as an international border between the United States and Canada. The exact location is latitude 43.081528 and longitude -79.064240.
The falls are located 17 miles north-northwest of Buffalo, N.Y., and 75 miles south-southeast of Toronto between the twin cities of Niagara Falls, Ontario and Niagara Falls, N.Y.
Niagara Falls consists of three different waterfalls: the American Falls and the Bridal Veil Falls in the United States and the Canadian "Horseshoe" Falls in Canada. In 1819, the international boundary line was drawn through Horseshoe Falls, but natural erosion and construction have led to dispute over the current boundary.
