“Walking on water”
The strongest sensation from the brazilian side is caught by crossing the tiny wooden bridge over the river.
Be warned: nor even your poncho will free you from getting really wet, and the sensation of the water flowing rapidly under your feet may get you sick.
Of course, you have the chance to go back at any time.
Kingdom of the Mist
The mist and haze are present everywhere in the falls. So, be prepared to wear your raincoat all the time, or to get wet.
Of course, you have the solution of buying locally a light poncho, not expensive, and that may become part of the fun.
