Misiones (the Argentine side)
Some places announce themselves before you ever see them. Iguazú Falls is one of them: long before the first cascade comes into view, you hear the roar and feel the spray drifting through the trees. Strung along the border between Argentina and Brazil, where the Iguazú River reaches the edge of a vast basalt shelf, this is one of the great waterfalls of the world, and standing before it is the kind of moment that reorders your sense of scale.
This is not a single waterfall but hundreds of them, spread in a great curving wall nearly two miles wide and wrapped in steaming subtropical rainforest. Sheets of water pour over every ledge, rainbows hang in the rising mist, and at the heart of it all is the Devil's Throat, the Garganta del Diablo, a horseshoe chasm where the river collapses into a thundering cloud of white. Toucans cross overhead, butterflies drift along the paths, and coatis nose through the undergrowth, so the wildlife is part of the show.
What makes the Argentine side so special is how close it lets you get. A network of walkways carries you right out over the river and into the spray, with one path leading to a platform that hangs above the very lip of the Devil's Throat. For the boldest, a boat ride pushes upriver and noses straight beneath the falls until everyone aboard is soaked and laughing. We pair the falls with the rhythm of your wider trip, easily folded into a few days between Buenos Aires and the south.
