Niagara Falls is a group of three waterfalls located on the Niagara River, which straddles the international border between the United States and Canada. The three waterfalls are Horseshoe Falls, American Falls, and Bridal Veil Falls. Horseshoe Falls is the largest and most well-known of the three, and is located on the Canadian side of the border. American Falls and Bridal Veil Falls are located on the American side.

Niagara Falls is known for its stunning natural beauty and its power, as well as its significance as a major source of hydroelectric power. The falls attract millions of visitors each year who come to experience the beauty of the cascading water and the mist that surrounds it. Visitors can view the falls from various vantage points, including observation decks, the Maid of the Mist boat tour, and the Niagara Falls State Park on the American side, and the Niagara Parkway and the Skylon Tower on the Canadian side.

Niagara Falls has a rich history, including its use by Native American tribes for fishing and trading, and its importance in the War of 1812 between the United States and Great Britain. Today, the falls remain an important symbol of natural beauty and power, as well as a major tourist destination and a source of renewable energy.
