The Maid of the Mist is a boat tour of Niagara Falls. 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 either the Canadian or American side of the river, returning to the starting point in each case.
