Iguassu Falls are the largest falls in the world and the most impressive that I have seen. The Falls sit on the border of Brazil and Argentina and each country offers a different and unique view of the Falls. There is only one hotel located in the National Park surrounding the Falls and this is a spectacular place to stay. There is also a magnificent bird park located outside the gates of the National Park with a large number of different species of Toucan, Parrots, Macaws and other interesting birds.
