The Iguazu national park covers the area of the waterfall which also attracts a large number of tourists. The nearest airports to the Iguazu waterfall are the Argentine Cataratas del Iguazú International Airport and Brazilian Foz do Iguaçu International Airport. Buses and taxis ply between the airport and fall thus making it convenient for the tourists.
