Welcome to one of the most breathtaking spectacles on planet Earth. You are standing within the Iguaçu National Park in Brazil, the gateway to a massive system of two hundred and seventy five individual waterfalls that stretch across the border with Argentina. The name 'Iguazu' comes from the indigenous Guarani words 'Y', meaning water, and 'Guasu', meaning big—and as you listen to the thunderous roar around you, you will understand why 'Big Water' is the only way to describe this place. This park, established in nineteen thirty-nine, protects one of the most important remnants of the Atlantic Forest in South America. As you begin your journey today, prepare to experience not just a tourist attraction, but a living ecosystem that UNESCO has recognized as a World Heritage site for its 'Outstanding Universal Value'.
