Frequently asked questions about the Iguazu Falls

What are the Iguazu Falls?

The Iguazu Falls are made up of around 275 waterfalls along approximately 3 kilometers of the Iguazu River. The most famous fall is the Devil's Throat, a huge gorge where the water falls with such intensity that the steam and noise make the experience almost hypnotic.
When you read terms like Iguazu cascades, Iguazu waterfalls or Iguazu cataract, they are all referring to this same set of falls.

When is the best time to visit the Iguazu Falls?

The Iguazu Falls are impressive at any time of year, but the scenery changes according to the season. In the flood season, usually between summer and early fall, the volume of water is greater and the visual impact is even more dramatic.
In the drier season, usually between winter and early spring, the water may be a little less abundant, but you gain in visibility of the trails, walkways and rock formations. The choice depends on what you value most: brute force or detail.

Visiting the Iguazu Falls from the Brazilian side

The Brazilian side is known for its panoramic views of almost the entire set of falls. The main route is well signposted and relatively short, with a trail that follows the river bank and several viewpoints along the way.
At the end, a footbridge brings you close to the Devil's Throat, offering one of the most iconic images of the falls, with accessible platforms and a structure prepared to receive visitors of all profiles.

Visit the Iguazu Falls from the Argentinian side

The Argentine side offers a more immersive experience, with several kilometers of walkways over the river and next to the falls. You can walk the Upper Circuit, with views from the top, and the Lower Circuit, closer to the base, where you can feel the water and humidity in the air.
The Devil's Throat is accessible by an ecological train and a long walkway that takes you to the edge of the gorge, one of the most impressive spots in the entire park.

Foz do Iguaçu and Puerto Iguazú: far beyond the waterfalls

In Foz do Iguaçu, you'll find attractions such as the Itaipu dam, one of the largest hydroelectric complexes in the world, the Three Borders Landmark, the Bird Park, the Buddhist Temple and themed museums. Puerto Iguazú, on the Argentine side, completes the trip with restaurants, local produce markets, casinos and its own Three Borders Landmark, overlooking the confluence of the Iguazú and Paraná rivers.

How much time should you allow for the Iguazu Falls?

In general, calculate half a day for the Brazilian side and a full day for the Argentinian side, which has more trails and circuits. For a complete experience, including extra tours and visits to both cities, the ideal is to spend between two and three days in the region.

Are the Iguazu Falls one of the 7 Wonders of the World?

The Iguazu Falls were voted one of the New 7 Wonders of Nature in 2011, in an international competition organized by New7Wonders. This recognition reinforces the park's environmental and tourist importance on a global scale.
