One of the three great falls in world (the others being Niagara and Victoria), Iguacu put on quite a show for us. Thanks to recent rains, the river was running about three times higher than average. That washed out one of the best vantage points on the Argentine side, but made for great viewing otherwise.
That's the Garganta Del Diablo -- the Devil's Throat -- off to the left.

One of the nicest hotels we've ever experienced. The Hotel das Cataratas.
