Iguaçu National Park
One of the world’s largest waterfalls cascades across the Brazil–Argentina border within a biodiverse subtropical sanctuary that spans over 185,000 hectares of pristine forest.
At a glance
Iguaçu National Park protects a landscape of extraordinary natural drama: a waterfall system extending over 2,700 metres stretches across the Paraná Plateau, generating clouds of spray that nourish lush subtropical vegetation. The park comprises 185,262.5 hectares and shares its border with Argentina’s Iguazú National Park, forming a transnational conservation zone of about 260,000 hectares combined.
History
The park was established by federal decree on 10 January 1939, making it one of Brazil’s early protected areas. It gained recognition as a UNESCO World Heritage Site in 1986, acknowledging both its geological significance and ecological value. Today, the Chico Mendes Institute for Biodiversity Conservation manages the site.
What you see
The Iguaçu Falls dominate the landscape, with water plunging across a cliff face of 2,700 metres. The mist and spray create perpetual rainfall within the forest, sustaining dense vegetation adapted to constant moisture. Dense subtropical forest canopy surrounds the falls, with viewing platforms positioned to reveal the waterfall’s scale and power from multiple vantage points.
Cultural significance
The park ranks among the world’s most remarkable natural monuments. Its ecological importance extends beyond Brazil; shared management with Argentina reflects collaborative conservation of a binational ecosystem. The waterfall has inspired artists, writers and explorers, symbolizing the raw power of South American nature and the necessity of cross-border environmental stewardship.
