What are Iguazú Falls and why are they so famous?

Iguazú Falls is one of the largest waterfall systems in the world. It is located on the border between Argentina and Brazil, inside two national parks: Iguazú National Park in Argentina and Iguaçu National Park in Brazil. The waterfalls are part of the Iguazú River, which forms the natural border between both countries.

There are around 275 waterfalls in total, spread across almost 3 kilometers. Some of them are small, while others are huge and extremely powerful. The most famous one is called the Devil’s Throat, a massive waterfall where thousands of liters of water fall every second.

Visiting Iguazú Falls is special because you can see the waterfalls from very close, walk above them, below them, and even take a boat ride that goes right under the water. Because of its beauty and size, Iguazú Falls was declared a UNESCO World Heritage Site and also chosen as one of the New Seven Natural Wonders of the World.

Where are Iguazú Falls located?

Iguazú Falls is located in South America, between Argentina and Brazil.

On the Argentine side, the closest city is Puerto Iguazú.
On the Brazilian side, the closest city is Foz do Iguaçu.

Both cities have airports and hotels, so you can stay in either one. Many travelers visit both sides of the falls because each side offers a different view. Argentina has the closest and most immersive experience. Brazil has the best panoramic views.

Visiting Iguazú Falls from both countries is easy, and most people cross the border without problems.

Why visiting Iguazú Falls is different from other waterfalls

Many people compare Iguazú Falls with Niagara Falls or Victoria Falls, but Iguazú feels very different. First, the number of waterfalls is much bigger. Instead of one main waterfall, you see hundreds of them surrounded by jungle.

Second, the park is very large. You can walk for hours on trails, bridges, and platforms. Third, the nature is wild. It is normal to see butterflies, monkeys, birds, and even coatis walking near the paths.

Fourth, you can get very close to the water. In some places, the spray is so strong that you will get completely wet. Visiting Iguazú Falls feels less like visiting a viewpoint and more like exploring a natural world.
