This was truly an amazing trip and something we will remember for a lifetime. There are two videos below to give you a taste, but we took many more pictures and videos that we will upload to facebook at a later date.
The first video is at the top of the Garganta del Diablo (Devil's Throat). It's a giant horseshoe shaped waterfall that is the border between Argentina and Brazil. The sheer force and quantity of water rolling over the edge prevents you from even seeing the bottom of the waterfall because it is obscured by mist. We could see the mist rising from Garganta del Diablo from the plane. It is definitely the most impressive waterfall.
The second video is from a view point at the other edge which allows you to see the entirety of Iguazu Falls. As you can see, the falls are so big, you can barely see the other side. From here, you can only see the mist coming from the Garganta del Diablo.
