Niagara Falls is located in both the U.S. and Canada. The falls mark the border between the two countries with one of its waterfalls being on American soil and the other on Canadian. For the American Falls, it is addressed 301 Prospect St., Niagara Falls, NY.

Niagara Falls actually belongs to both the United States and Canada, as it sits directly on the international border. The falls consist of three distinct waterfalls. The Horseshoe Falls (the largest and most famous) is located mostly on the Canadian side, in the province of Ontario. The American Falls and the smaller Bridal Veil Falls are located entirely within the United States, in the state of New York. The border between the two countries runs through the center of the Niagara River and through the crest of the Horseshoe Falls. Because of this, tourists can view the falls from either country. The Canadian side is generally considered to have the "better" panoramic views, while the American side offers a more "up-close" nature-park experience through the Niagara Falls State Park. To get the full experience, many travelers cross the "Rainbow Bridge" to visit both sides, though you will need a passport or an enhanced driver's license to clear customs and immigration during the crossing.
