What is Iguaçu Falls?

June 21, 2024


Iguaçu Falls, also known as Iguassu Falls or Iguaçu Falls, is one of the most breathtaking natural wonders in the world. Located on the border between Brazil and Argentina, this magnificent waterfall system consists of 275 individual falls cascading over a 2.7-kilometer stretch of the Iguaçu River. The falls are surrounded by lush rainforest, making it a truly spectacular sight to behold.


The history of Iguaçu Falls dates back thousands of years, with indigenous tribes inhabiting the surrounding area long before the arrival of European explorers. The falls were first discovered by Spanish explorer Álvar Núñez Cabeza de Vaca in 1541, and later explored by Portuguese explorer Álvaro Nunes in 1549. The name “Iguaçu” is derived from the Guarani words “y” (water) and “ûasú” (big), reflecting the grandeur of the falls.


Iguaçu Falls is situated within the Iguaçu National Park, a UNESCO World Heritage Site that spans over 185,000 hectares of protected land. The falls are formed by a series of basalt cliffs that have eroded over time, creating a stunning natural amphitheater. The tallest waterfall in the system, known as Devil’s Throat, plunges over 80 meters into the churning waters below.

Flora and Fauna

The surrounding rainforest is home to a diverse array of plant and animal species, including jaguars, tapirs, and howler monkeys. The park is also a haven for birdwatchers, with over 400 species of birds recorded in the area. Visitors to Iguaçu Falls can explore the park’s extensive network of hiking trails and boardwalks, offering unparalleled views of the falls and the surrounding wildlife.


Iguaçu Falls is a popular tourist destination, attracting millions of visitors from around the world each year. The falls can be accessed from both the Brazilian and Argentine sides, with each offering unique perspectives on the cascading waters. Boat tours, helicopter rides, and eco-friendly excursions are available for those looking to experience the falls up close.


Efforts to protect and preserve Iguaçu Falls and its surrounding ecosystem have been ongoing for decades. The Iguaçu National Park is managed by the Chico Mendes Institute for Biodiversity Conservation, which works to safeguard the park’s biodiversity and promote sustainable tourism practices. Conservation initiatives focus on combating deforestation, protecting endangered species, and promoting environmental education.

Myths and Legends

The indigenous Guarani people have long revered Iguaçu Falls as a sacred site, believing that the falls were created by a deity as a gift to the Earth. According to legend, the falls were formed when a jealous serpent split the river in two, creating the dramatic cascade that we see today. The Guarani also believe that the falls are a gateway to the spirit world, where the souls of the departed can find peace.

Impact on Local Communities

The tourism industry surrounding Iguaçu Falls has brought economic opportunities to the local communities in the region. Hotels, restaurants, and souvenir shops have sprung up to cater to the influx of visitors, providing jobs and income for residents. However, concerns have been raised about the environmental impact of tourism on the fragile ecosystem of the falls, prompting calls for sustainable development practices.

Future Challenges

As climate change continues to threaten the stability of ecosystems worldwide, Iguaçu Falls faces challenges in maintaining its natural beauty and biodiversity. Increased deforestation, pollution, and habitat destruction pose significant risks to the health of the falls and the surrounding rainforest. Conservation efforts must be redoubled to ensure that future generations can continue to marvel at this awe-inspiring natural wonder.


In conclusion, Iguaçu Falls stands as a testament to the power and beauty of nature, captivating visitors with its sheer size and majesty. As one of the most iconic waterfalls in the world, Iguaçu Falls serves as a reminder of the importance of conservation and sustainable tourism practices in preserving our planet’s natural wonders for generations to come.
