Together, the Brazilian and Argentine parts of the park cover an area of about 260.000 hectares. One of the world’s largest waterfalls, Iguazu Falls is the biggest attraction of both national parks, although the Brazilian side has only 20 percent of the waterfall’s area, the remaining 80 percent on the Argentine side. The park is managed by the Chico Mendes Biodiversity Conservation Institute (ICMBio).
On 17th November 1986, at a conference in Paris, Iguazu National Park was declared a Natural Heritage of Humanity and is one of the largest forest conservation areas in South America.
