The roar is deafening. The wind shifts and a new sheet of mist covers me and my camera. I am standing above Devil's Throat and it feels like one wrong step might send me straight to hell.

It's easy to see why it's called Devil's throat. The 250 ft drop separates the upper and lower Iguazu Rivers along the border of Brazil and Argentina is not something you want to take a ride down. But it is something you want to see.

Viewed from the Argentina side, you are able to take a series of metal catwalks over the wide river and eventually you will hear the roar coming out of seemed to be a pleasant little river.

Take a camera but make sure you take a plastic bag or casing to protect it when the wind shifts and covers you in spray which happens quite often.
