The Argentine side of Iguazú puts visitors on top of and beside the falls rather than looking across at them, and the morning belongs to that closer, wetter perspective before the road turns south through Misiones to a small, seasonal bridge built for exactly this kind of trip: a shortcut into Brazil's southern beach country.
Roughly 80 percent of the roughly 275 individual falls that make up the Iguazú system sit on the Argentine side, and the Parque Nacional Iguazú is built to get visitors right into the middle of them rather than looking across at a single panorama. A little electric train, the Tren Ecológico de la Selva, shuttles between three stations — Central, Cataratas, and Garganta — connecting the Circuito Superior and Circuito Inferior, walkways along the tops and bases of a string of named falls, to the Garganta del Diablo, the most powerful of them all, reached by an 1,100-metre footbridge laid directly over the river above an 80-metre drop. A full exploration of the Argentine side is usually reckoned as a full day's outing; with a morning in hand, the Garganta del Diablo walk is the one piece not worth skipping, with whichever of the two circuits fits the remaining time layered on around it.
Deleting this waypoint is permanent and cannot be undone.
