Misiones province, which takes its name from the missions built by the Jesuits in the 17th century, is widely forested and is where most of the tea-like drink known as mate is grown.

The Iberá (from a native guaraní word meaning ‘brilliant waters’) are wetlands that cover over a million hectares and are fed by the river Paraná and its tributaries. The water levels vary throughout the year, and the area is very rich in wildlife, particularly birds (over 350 species).
