Both Brazilians and Argentineans will argue that their side of the falls is better (the river is the border between the two countries), so we thought we would check out both. The Brazilian side of the falls has a nice walk with an amazing panoramic view and a platform that lets you look over the edge of the falls facing the Garganta del Diablo (Devil's Throat). So before we crossed the border back in to Argentina we spent an afternoon on the Brazilian side and watched the sun set with little coatis (animals like raccoons).
Even though we took loads of photos, they don't really do it justice. We took a few videos as well so you can get a sense of how massive it was, which we will post separately. To be honest, you have to go there to appreciate it.
