The title of the "most famous" waterfall is typically a three-way contest between Niagara Falls, Victoria Falls, and Iguazu Falls, each located on significant international borders. Niagara Falls is situated on the border between Ontario, Canada, and New York, USA; it is world-renowned for its massive water volume and accessibility. Victoria Falls, the largest curtain of falling water in the world, is located on the Zambezi River between Zambia and Zimbabwe in Southern Africa. Iguazu Falls, a breathtaking system of 275 individual drops, spans the border of Argentina and Brazil. For those seeking the world's highest waterfall, Angel Falls is located deep within the Canaima National Park in Venezuela, dropping a staggering 979 meters (3,212 feet). In 2026, the HSBC Rain Vortex in Singapore's Jewel Changi Airport has also gained global fame as the world's tallest indoor waterfall, proving that "famous" landmarks can now be found in the heart of urban transportation hubs as well as in remote jungles.
