Nestled on the border between Argentina and Brazil, Iguazú National Park (Parque Nacional Iguazú) is one of the most breathtaking natural attractions on Earth. It is home to the world-famous Iguazú Falls, a series of over 270 cascading waterfalls spread over 2.7 kilometers, surrounded by lush subtropical rainforest teeming with wildlife.
Recognized as a UNESCO World Heritage Site since 1984, the park offers not only jaw-dropping scenery but also vital protection to one of South America’s richest ecosystems. Whether you’re an adventure seeker, nature lover, or casual tourist, Iguazú National Park offers a life-changing experience.
A Glimpse into History
The name “Iguazú” comes from the Guaraní language, meaning “big water” (y = water, guasu = big). The falls were first documented by Spanish explorer Álvar Núñez Cabeza de Vaca in 1541, but indigenous people had long revered this sacred site. Over centuries, the area transformed from indigenous land to a national treasure with robust eco-tourism infrastructure.
Top Attractions in Iguazú National Park
1. Iguazú Falls (Cataratas del Iguazú)
The crown jewel of the park, the falls are taller than Niagara and wider than Victoria Falls. The most famous section is the Devil’s Throat (Garganta del Diablo) — a thunderous, U-shaped chasm where 14 massive waterfalls drop 80 meters with unbelievable force.
2. Devil’s Throat Boardwalk
An elevated catwalk takes visitors across the Iguazú River right to the edge of Devil’s Throat. The experience is surreal, especially when water vapor mists the air and rainbows dance in the sunlight.
3. Upper and Lower Circuit Trails
- Upper Circuit: Panoramic views of the waterfalls from above.
- Lower Circuit: A more immersive trail that gets you closer to the base of the falls — expect to get wet!
4. Macuco Trail and Salto Arrechea
This 3.5 km trail leads to a hidden waterfall and offers the best chance to spot wildlife like toucans, monkeys, and even jaguars (though sightings are rare).
5. Eco-Train (Jungle Train)
A quiet, gas-powered train transports visitors through the forest to different trailheads and viewing platforms, enhancing the experience with minimal environmental impact.
Wildlife and Biodiversity
Iguazú National Park is a biodiversity hotspot with:
- 400+ bird species (e.g., toucans, parrots, hummingbirds)
- 80+ mammals (capuchin monkeys, coatis, jaguars, ocelots)
- Amphibians and reptiles, including colorful frogs and caimans
- Over 2000 plant species, from orchids to towering trees
