The falls originate on the Iguazu River and extend for about 2 miles in a fascinating semi-circle. The Iguazu Falls lie on the border between the Brazilian state of Paraná and the Argentine Misiones province.
The waterfall presents some stunning sights that are highly recommended for all the tourists visiting the region. Apart from enjoying the views you can walk along the walkways to the top and to the bottom of the falls, take a helicopter ride to see the entire area, go kayaking and also ride a jet boat to explore the entire waterfall. You can also enjoy the birds and wildlife, from both the countries.
