Flying from Sao Paulo to Iguazu Falls, or just the cataratas (waterfalls) locally, you begin to sense that you are close. From not being able to identify where the building ends and the sky begins over Sao Paulo to not being able to see a trace of human existence near the falls. Once actually in sight, there's a cloud of mist forcefully being kicked back into the atmosphere from the force of the water. And that's just from the plane...
- The Brazil side has all the views of the falls from below and essentially under the falls. The Argentinean side has an insane view from above the drop which you walk to on wood walkways over the river.
- The Brazilian side has more to do, but a full day will cover it. The Argentinean side can be done in half a day for the minimum time you could be there.
- Bring a raincoat! Beware of the coati (like little racoons) eating your lunch!
