Wednesday and Thursday were spent at Iguazu Falls, in northern Argentina, right on the border with Brazil. I was meant to fly in to Iguazu on Tuesday nigh and take part in a 6 hour group tour on Wednesday. However, the weather gods changed that with a diversion at Buenos Aires and an overnight stay there, then a late departure the next morning.

However, it all worked out and these stunning pics are the result.

The Iguazu Falls, Iguazú Falls, Iguassu Falls, or Iguaçu Falls (Spanish: Cataratas del Iguazú [kataˈɾatas ðel iɣwaˈsu]; Guarani: Chororo Yguasu [ɕoɾoɾo ɨɣʷasu]; Portuguese: Cataratas do Iguaçu [kataˈɾatɐʒ du iɡwaˈsu]) are waterfalls of the Iguazu River on the border of the Argentine province of Misiones and the Brazilian state of Paraná. They are the largest waterfalls system in the world.[2] The falls divide the river into the upper and lower Iguazu. The Iguazu River rises near the city of Curitiba. For most of its course, the river flows through Brazil; however, most of the falls are on the Argentine side. Below its confluence with the San Antonio River, the Iguazu River forms the boundary between Argentina and Brazil.

The name "Iguazu" comes from the Guarani or Tupi words "y" [ɨ], meaning "water", and "ûasú "[waˈsu], meaning "big".[3] Legend has it that a deity planned to marry a beautiful woman named Naipí, who fled with her mortal lover Tarobá in a canoe. In a rage, the deity sliced the river, creating the waterfalls and condemning the lovers to an eternal fall.[3] The first European to record the existence of the falls was the Spanish conquistador Álvar Núñez Cabeza de Vaca in 1541.
