No, not Niagara! Experience the wrath of Iguassu Falls in their fullest by speedboating under them in Argentina or Brazil (you visit both or either side of the waterfall). Rated as one of the worlds largest and most breath taking waterfalls, Iguassu spans across three countries -Uruguay, Brazil and Argentina. There are various walking trails around and over the waterfalls offering beautiful vistas, but to experience the full force, take a ride on the speed boat as enjoy an unforgettable baptism as the water falls from over a hundred feet high in its full force to scare you and completely drench you. The ride costs around $40 and I recommend doing it on the Argentinian side.
