Niagara is the world's most famous waterfall; Angel Falls is the tallest. And Victoria Falls has the largest single cascade. But the most beautiful? For us that honour falls to Iguazu Falls, on the border between Argentina and Brazil. It is made up of some 275 cascades, spread over an incredible width of 2km and has an average flow of 1.3 million litres a second. All very impressive, but the winning features of the site for us are its pristine rainforest setting and its fabulous shape, which at one point allows you to stand surrounded by walls of water on three sides.
