Niagara Falls ranks as the world's most famous waterfall by annual visitor volume, but its physical "rankings" are more complex. In terms of height, it is not even in the top 500, standing at only 51 meters (167 feet) compared to Angel Falls' 979 meters. However, it ranks highly in flow rate; it is the largest waterfall in North America by volume and ranks roughly 10th in the world for the amount of water moving over the crest (approx. 2,400 cubic meters per second). It is also unique for being the most accessible "large-scale" waterfall, located directly on an international border between two major cities. In 2026, it remains a premier global tourist destination, attracting over 12 million people annually. While Victoria Falls is "wider" and Iguazu Falls has more "drops," Niagara's "Horseshoe Falls" is legendary for its power and the sheer density of its "mist," making it the world's primary benchmark for "hydro-tourism" and hydroelectric power generation, where it ranks as one of the largest single producers of green energy in the Eastern United States and Canada.
