The exquisite Iguazu Falls are situated in the south of Brazil, at the Iguazu River, 650 km from the Brazilian coast, near the border with Argentina. The Falls appear a little before the Iguazu River meets the Paraná River, where a part of Iguazu plunges itself for nearly 3 km, creating an unexpected and breathtaking natural spectacle. The mist and foam caused by these falls create permanent rainbows. The Iguazu Falls are larger and wider than Niagara Falls. While Niagara is a tourist town, the Iguazu Falls are located in a national park.
