Visit Foz do Iguaçu

More than 250 waterfalls along a front of nearly 3 km, a gorge where the river plunges with a constant roar, a forest full of coatis and toucans: Foz do Iguaçu is experienced from two banks. One day on the Brazilian side for the panorama, one day in Argentina for immersion, half a day for Itaipu.

Why go to Foz do Iguaçu?

Foz do Iguaçu, in the state of Paraná, is the Brazilian city that gives access to Iguaçu Falls, shared with Argentina. The national parks on both banks are UNESCO World Heritage Sites. The city sits on the triple border with Argentina and Paraguay and is home to the binational Itaipu dam.

Foz do Iguaçu must-sees

The falls from every angle, plus a few stops worth the detour between visits.

Devil's Throat

A U-shaped gorge carrying the falls' greatest volume of water; on the Brazilian side, a walkway reaches out to the foot of the cascades in a permanent cloud of spray.

Argentine lower circuit

A loop of walkways at water level on the Argentine side, passing several cascades with views of San Martín island and its rainbows.

Parque das Aves

A bird park opposite the Brazilian falls entrance, devoted to Atlantic Forest birds, with large walk-through aviaries where you stroll among toucans and macaws.

Itaipu dam

A giant binational structure on the Paraná, visited by panoramic bus or technical tour, with the dam lit up on certain evenings.

Marco das Três Fronteiras

A lookout over the meeting of the Iguaçu and Paraná rivers, with views of the Argentine and Paraguayan banks, enlivened at sunset by a cultural show.

Macuco Safari

An inflatable boat ride from the Brazilian park that heads upriver to the foot of the falls for a spectacular soaking; bring a change of clothes.

Omar Ibn Al-Khattab Mosque

A white-domed mosque with minarets, symbol of Foz's community of Lebanese origin, open to visitors wearing clothing that covers arms and legs.

What to do in Foz do Iguaçu, from the falls to the triple border?

The Brazilian side of the national park

The park entrance is about 20 minutes from the centre, on the airport road. An internal bus takes you to the start of the falls trail, about 1.2 km long, which follows the gorge with sweeping views of the Argentine falls opposite. It ends with a walkway jutting out at the foot of the Devil's Throat, where you are soaked within seconds: bring a poncho. Half a day is enough; arrive at opening time to avoid the queues for the buses. It is one of the great natural sites of Brazil.

The Argentine side and Puerto Iguazú

The Argentine park, reached in 30 to 45 minutes via the Tancredo Neves bridge and the town of Puerto Iguazú, needs a full day. Two walkway circuits, upper and lower, bring you very close to the falls, and a small train leads to the Garganta del Diablo walkway, about 1 km long above the river. The border crossing takes anything from a few minutes to over an hour depending on traffic: carry your passport and set off early to enjoy the park ahead of the groups.

Itaipu and the Paraná river

North of the city, the Itaipu dam, built with Paraguay on the Paraná, ranks among the largest hydroelectric plants in the world. The panoramic bus tour runs along the dam wall and the spillway, while a technical tour goes inside the structure. In the late afternoon, the Marco das Três Fronteiras, at the confluence of the Paraná and Iguaçu rivers, shows Brazil, Argentina and Paraguay in a single glance. Set aside half a day for both, with Itaipu tickets booked online.

The city centre and its communities

Foz's grid-plan centre is not a destination in itself, but it gathers affordable hotels, barbecue restaurants and the urban bus terminal. Bus line 120 links the terminal to the airport and then to the falls entrance in about 40 minutes. The city has large communities of Lebanese and Chinese origin, reflected in a large mosque and a Buddhist temple, each visited in under an hour. For a three-night stay, staying along Avenida das Cataratas cuts travel time to the park.

Water flow and climate

The volume of the falls varies greatly from season to season and year to year: spectacular floods can close some walkways, while droughts reduce the show. The southern summer, from December to March, is hot and humid, often above 30 °C, and coincides with Brazilian holidays. April-May and September-October offer a good balance between water flow, temperature and crowds. In June and July, nights can drop below 10 °C: pack a warm layer.

Frequently asked questions about Foz do Iguaçu

Should you see Iguaçu Falls from Brazil or from Argentina?
Ideally both. The Brazilian side gives the overall view in half a day, while the Argentine side brings you close to the falls along several kilometres of walkways and needs a full day. With only one day, choose Argentina for immersion, giving up the grand panorama.
Can you visit both sides of the falls on the same day?
It is possible but exhausting: the border crossing, transfers and the size of the Argentine park leave little time on site. Better to spend one morning on the Brazilian side and the whole next day in Argentina, leaving early to beat the groups.
Is the Friendship Bridge to Ciudad del Este worth the detour?
Only if you are interested in shopping. The bridge is often jammed, the city is noisy and counterfeits are widespread. If you go, keep your documents on you, watch your belongings and check the border formalities that apply to your nationality.
What happens at Iguaçu Falls during a flood?
During floods, the Garganta del Diablo walkway on the Argentine side and some trails may close for safety reasons, and the water turns brown. In dry spells, the cascades separate and the show loses power. Check the official channels of both parks a few days before your visit.
How do you get from central Foz to the falls without a car?
Urban bus line 120 leaves from the central terminal, stops at the airport and ends at the Brazilian park entrance, in about 40 minutes. For the Argentine side, regular buses link Foz to Puerto Iguazú, with a connection to the park; taxis and transfers are quicker at the border.
Does the Macuco Safari really get you wet?
Yes, completely. The boat moves close to the falls until it passes through the spray, sometimes under a cascade: unprotected clothes, bags and phones get drenched. Waterproof bags are offered on site, and it is best to wear swimwear under light clothing.
Are the coatis at Iguaçu Falls dangerous?
They are not aggressive, but being used to people, they rummage through bags and may bite or scratch when you hold food. Injuries are reported regularly: do not approach or feed them, and eat in the designated areas.
