Taller than Niagara Falls, twice as wide with 275 cascades spread in a horseshoe shape over nearly two miles of the Iguazu River, Iguazú Falls are the result of a volcanic eruption which left yet another large crack in the earth. During the rainy season of November - March, the rate of flow of water going over the falls may reach 450,000 cubic feet (12,750 cubic m) per second.
Iguazú Falls, called Foz do Iguaçu in Portuguese, andCataratas del Iguazú in Spanish, lie on the Argentina - Brazil border and are a UNESCO World Natural Heritage Site.
The falls are part of a singular practically virgin jungle ecosystem protected by Argentine and Brazilian national parks on either side of the cascades. Two thirds of the falls are on the Argentinian side of the river where you can also tour Iguazú National Park where there are jungle trails and bird hikes. Plan a full day in the park to fully enjoy the wildlife flora and fauna.
It is possible to see the falls and surrounding area in a lightning trip but it is better to plan at least two days. The view from the Brazilian side is the most panoramic and there are helicopter rides out over the falls from Foz do Iguaçu. You may also take boat rides out to the falls. The light is best in the morning for photographs.
