Foz do Iguaçu is the Brazilian city at the famous waterfalls of Iguaçu and at the borders to Paraguay and Argentina. The waterfalls are higher than the Victoria Falls, wider than the Niagara Falls, they are the most exciting.
They are in the list of UNESCO World Heritage (the small national park in Argentina since 1984. the Brazilian national park since 1986). The water falls about 80 meters deep on a range of about 2700 meters, in more than 270 cascades. The name of the river comes fron the native tribe of the Guarani, in their language the word Yguazu means “big water”.
At the falls you will see millions of butterflies, many birds, if you are lucky sometimes monkees and caimans (but no reason to have fear, you are safe). It is home to many rare and endangered species of flora and fauna, among them the giant otter and the giant anteater. The clouds of spray produced by the waterfall are conducive to the growth of lush vegetation.
A part of the falls is on the Argentinian side, the other one on the Brazilian. For the Argentinian side you should plan a complete day in the national park there, on the Brazilian half a day. There, close to the entrance of the national park is a marvellous small zoo mainly with birds and plants of the region.
Another interesting place is Itaipu, the still largest hydroelectric plant in the world, producing 90% of the needed electricity of Paraguay and 20% of the need of Brazil. The dam has a lenght of 7235 m,and a height of 195 m. The water passing is 40 times as much as the average flow at the waterfalls of Iguaçu . It can be visited by day, too, but it is worthwhile do go there in the evening as it will be illuminated.
