Iguazu Falls is one of the biggest waterfalls in the world as it runs for 1.7 miles. So that you get a idea on size, less half are in the Brazil side but you do get a much better panoramic view. On most clear and sunny days, you would see a rainbow and the view is simply beautiful and magical. The entrance on the Brazil side brings you right to the waterfalls after a 15-20 minute bus-ride from the ticketing office. If you're wondering which side gives you the best views and the best photos- I'd vote Brazil-side. You can also get up close the waterfalls, but be warned that they can give out a lot of mist, even at a distance and this would be where you'd need a poncho!
