The Maid of the Mist is a boat tour of Niagara Falls, New York, USA. (The actual boats used are also named Maid of the Mist, followed by a different Roman numeral in each case.) The boat starts off at a calm part of the Niagara River, near the Rainbow Bridge, and takes its passengers past the American and Bridal Veil Falls, then into the dense mist of spray inside the curve of the Horseshoe Falls, also known as the Canadian Falls. The tour is available starting from the American side of the river, returning to the U.S. landing.
