About Cataratas del Iguazú
Iguazú Falls form a semicircular front about 2.7 km wide where the Iguazú River drops over basalt steps, right on the border between Argentina and Brazil. There are around 275 individual falls, and about 80% of them are on the Argentine side. The name comes from Guaraní and roughly means big water. UNESCO listed the Argentine park as a World Heritage Site in 1984 and the Brazilian one in 1986.
On the Argentine side you walk among the falls and above them; the Brazilian side gives a better overall panorama, which is why many people do both. Average flow is around 1,500 cubic meters per second, but it varies a lot: after rain in the Brazilian basin the water turns brown, louder, with a thick mist that soaks the viewpoints. Besides daytime visits, the park runs guided full-moon and sunset tours with limited places.
Local tip
Bring swimwear or clothes that can get wet and a bag for your phone: the official site suggests it, and at high flow the mist drenches the viewpoints.
