About this subject

Iguazu Falls are located within Iguazu National Park in Paraná, Brazil, and Iguazú National Park in Misiones, Argentina. This waterfall system was declared a UNESCO World Heritage site in 1984 and is one of the New7Wonders of Nature. It consists of approximately 275 individual falls spread over 2.7 kilometers, with heights reaching up to 82 meters. The most famous section, Devil's Throat (Garganta do Diabo), plunges 80 meters and discharges up to 1.5 million liters of water per second.

Geologically, the falls formed about 150 million years ago from volcanic eruptions that deposited a basalt layer over sandstone. Continuous erosion carved the cliffs and islands that define the current landscape. The region hosts extraordinary biodiversity, including endangered species such as the jaguar and the harpy eagle, along with over 2,000 vascular plant species.

Compared to other major waterfalls, Iguazu is wider than Victoria Falls and taller than Niagara. The average water flow is 1,746 cubic meters per second, fluctuating with rainy seasons. Tourism is robust, with over 1.7 million visitors annually, who explore walkways and trails on both the Brazilian and Argentine sides.

According to Guaraní legend, the falls were created by the god Mboi, who became enraged at a lovers' escape and split the river into cascades. The first European to sight them was Spanish explorer Álvar Núñez Cabeza de Vaca in 1542. Today, Iguazu Falls symbolize conservation and remain one of South America's most iconic destinations.
