The Iguazu Falls is a horseshoe-shaped waterfall, which is also a U shape, but this is not particularly clear in the Brazilian section, as 90% of the Iguazu Falls are in Argentina and only 10% in Brazil. Watching the Iguazu Falls in Brazil is mainly to watch its frontal panorama and the amazing sound of the waterfalls, while the Argentine territory can feel the waterfall from top to bottom. Iguazu National Park is built in Argentina and Brazil, and most people will choose to watch the Iguazu Falls in Argentina, with a better viewing angle and a larger waterfall area. Although I really want to go there, I dont have an Argentine visa, so I chose to watch Iguazu in Brazil.
