Pictures of Iguassu Falls (Foz do Iguaçu)
Although this is probably the place where every tourist stops on their trip across Brazil, it is definitely worthwhile visiting. The waterfalls are said to be much larger than Niagara Falls. Indeed, you can spend two days there to explore the various falls from all sorts of lookouts. When you go, make sure you have a raincoat with you.
The city of Iguassu doesn’t seem to be very interesting. It is, however, right at the border to Argentina and Paraguay. Take some time to cross the border and go shopping with the other Brazilians in Ciudad del Este, Paraguay. This is probably the place where you can the world’s cheapest electronics. (But you must bargain!)
