Iguazu Falls: the three frontiers of the "big water" and a river "resembling the sea"

The Iguazu Falls and the mouth of the Paraná river mark the largest triple border in South America, bringing together Brazil, Argentina, and Paraguay in a single geographical point. The region is known as the "three borders" of water, where the fusion of the two rivers defines the territorial boundaries of the three South American countries. The article describes the meeting of these waters as a natural spectacle that connects and at the same time separates neighboring nations. The expression "big water" refers to the grandeur of the waterfalls and the volume of the rivers that form this natural border, while the Paraná river is compared to the sea due to its extent and regional importance. This region represents not only a geographical curiosity, but also a strategic point of integration between the three countries.
