Iguazu Falls National Park

The Iguazu River -which means large water in Guaraní- flows into the Parana River creating a water blanket 1,500 meters wide, dotting islands and islets until it reaches a lava ravine formed 120 million years ago.

The Iguazu Falls National Park preserves the greatest biodiversity of the ecoregion of the Parana jungle.

During the course of the year, the temperature generally ranges from 12 ° C to 32 ° C in summer and 14 ° C in winter. Therefore, the best time to visit the Park is simply… all year round.

Specimens of natural flora such as rosewood and hearts of palm compete into decorating the environment.
