Iguazu ranks alongside Niagara and Victoria Falls as one of the world’s great waterfalls. There are 275 separate waterfalls running along the border with neighbouring Brazil.
The falls are shared by Iguazú National Park (Argentina) and Iguaçu National Park (Brazil), which are both designated UNESCO World Heritage Sites. Brazil has around 20% of the falls, whereas the Argentina side makes up almost 80%.
The abundant flora and fauna of the surrounding tropical forest includes some 500 species of butterfly, 400 birds and 2,000 plants which flourish in the nearby tropical forest, with orchids growing next to pines, bamboo next to palms, and mosses beside lianas and colourful begonias.
Access through the rainforest is by small train from the visitor centre to a point where a walkway leads over the river to the top of the Devil's Throat. Other walkways provide access to the long run of falls on this side, and to the boat across to San Martin Island in the middle of the river. On this side you can take a powerful inflatable boat trip right up to the tumbling columns of water.
A network of paths and walkways affords fine views – we recommend visiting the national park on the Brazilian side too.
