The plunging water has worn away the lower rocks so that there are caves behind the sheets of water of both falls. Sightseers may enter the Cave of the Winds at the foot of the American falls and get an unusual view. The Canadian falls has carved a plunge basin 59 meters deep. Both the United States and Canadian governments have built parks, viewing platforms, paths, and highways. // The Niagara Reservation State Park was established in 1885 and is New York's oldest state park. It includes an observation tower, elevators that descend into the gorge at the base of the American falls, and boat trips into the waters at the base of the Horseshoe Falls. At night colored lights illuminate the falls and create a charming spectacle which viewers find hard to turn away from. The park area has long been a tourist site and a favorite spot for couples to spend their honeymoons.//
