The destination
What to expect in Foz do Iguaçu
Foz do Iguaçu sits at the far western tip of the state of Paraná, where the Iguaçu River meets the Paraná River, on the border between Brazil, Argentina and Paraguay. The city grew up around two works of enormous scale: Iguazu Falls, with about 275 drops spread along a cliff face of almost three kilometers, and the Itaipu hydroelectric plant, which for years was the largest in the world in power generation. They are only a few kilometers apart and can be seen on the same trip.
The falls lie inside Iguaçu National Park, a protected area of Atlantic Forest that has been a UNESCO World Heritage Site since 1986. On the Brazilian side, a walkway leads to the base of the Devil's Throat, the largest of the drops, where the water and the mist soak everyone up close. On the Argentine side, in Puerto Iguazú, longer walkways reach the edge of the Throat from above. The two sides are different, and many people visit both on separate days.
Besides the water, Foz lives off the border. The Three Borders Landmark marks the exact point where Brazil, Argentina and Paraguay meet on the rivers, with obelisks on all three banks. On the Paraguayan side, Ciudad del Este draws shoppers, and Parque das Aves, a bird park next to the entrance of the national park, brings together toucans, macaws and Atlantic Forest birds in walk-through aviaries. It is a destination that combines grand nature, engineering and the comings and goings of three countries.

Frequently asked questions
Frequently asked questions about Foz do Iguaçu
What is the best time to travel to Foz do Iguaçu?
The falls are impressive all year. From June to August it rains less (97 to 145 mm) and highs are 24 to 26 °C, comfortable for walking the walkways. In summer, with highs of 32 to 33 °C, the flow is greater, but it is also hotter and rainier.
How many days do you need in Foz do Iguaçu?
Three to four days is enough for the Brazilian side of the falls, the Argentine side, the Itaipu plant and Parque das Aves without rushing. With 2 days you can see the essentials, but it is tight.
How do you get from Foz do Iguaçu airport to the city?
The airport (IGU) is about 13 km from the city, so the transfer is short.
Is it worth seeing both sides of the falls?
Yes. The Brazilian side offers the panoramic view of the whole group of drops and the walkway to the base of the Devil's Throat. The Argentine side, in Puerto Iguazú, has longer walkways that reach the edge of the Throat from above. They are different, complementary experiences.
Do you get wet at the falls?
Yes, and quite a lot. On the Devil's Throat walkway, on the Brazilian side, the mist from the drops soaks anyone nearby. Bring a raincoat and protect your electronics.
Is it a good destination to travel with children?
Yes. The walkways at the falls are accessible, Parque das Aves delights children with toucans and macaws up close, and a visit to Itaipu makes a good engineering lesson.
