This picturesque crater is located in the Iguazu River Falls region, located on the border between the Brazilian state of Paraná and the Argentine province of Machins, and is considered one of the amazing natural landmarks in the South American continent. 150 meters long, 80 meters wide, and amazing rainbows appear in this area, which result from the flow of the torrential river water, and its meeting with the sun's rays. The best location to view this view is the path on the Brazilian side that leads to a wonderful viewing balcony.
