Garganta del Diablo, Argentina

A 1.1km walkway across the placid Río Iguazú leads to one of the planet’s most spectacular sights, the ‘Devil’s Throat.’ The lookout platform is perched right over this amazingly powerful, concentrated torrent of water, a deafening cascade plunging to an invisible destination; vapors soaking the viewer blur the base of the falls and rise in a smoke-like plume that can be seen several kilometers away. It’s a place of majesty and awe, and should be left until the end of your visit.
