Foz do Iguaçu

The currency is the real, and credit cards and Pix work in practically every Brazilian business, even street vendors: even a chipa basket has a QR code hanging off it. 2026 ranges: coffee R$5–8, self-service lunch by weight R$35–55, dinner at a mid-range restaurant R$60–120 per person, all-you-can-eat R$90–160, a beer at a bar R$10–18, city bus R$5.00, an app ride within the city R$15–35, hostel R$70–140, mid-range hotel R$250–450, and a resort hotel on Rodovia das Cataratas R$600–1,500. Tickets weigh more than food: national park R$121–134, Parque das Aves about R$100–130, boat ride starting at about R$400, Itaipu visit R$48–185 depending on the circuit. On the Paraguayan side the dollar is king and the real is accepted at a bad rate. On the Argentine side bring pesos or a card, and check beforehand which rate your bank applies, because the Argentine rate moves fast. A 10% tip usually comes on the bill and is optional; taxis don't expect one. Avoid exchanging money at the makeshift counters on the Friendship Bridge: use a registered exchange house downtown with a receipt.

Airport: 11 km from downtown, on the way to the park

Foz do Iguaçu International Airport (IGU) is about 11 km from downtown via the BR-469, on the way to the national park, and gets direct flights from São Paulo, Rio, Curitiba, Brasília, Porto Alegre, and Campinas. The terminal was expanded by operator CCR in the 2020s. From the airport to downtown there are three prices for the same trip: the National Park line city bus for R$5.00, a taxi or app for R$45–80, and a hotel transfer for R$60–100 per person (2026). The international bus station is on Av. Costa e Silva, about 5 km from downtown, and runs long-distance buses: Curitiba in about 10 hours (640 km), São Paulo in about 15 hours, with direct routes to Asunción and Buenos Aires. On the Argentine side there's a second airport, Puerto Iguazú (IGR), about 25 km away, useful for those arriving from Buenos Aires.

City buses: R$5 and 90 minutes of transfers with the card

City buses are run by Foztrans and take the Cartão Único smartcard: the fare has been R$5.00 since May 2026, the same whether you pay on board in cash or by card, but only card users get the 90-minute free transfer. Pay on board and you'll pay twice for any trip that needs a change. The hub is the urban bus terminal (TTU) downtown, where lines leave for the National Park and the airport (the “120 Parque Nacional”), for the Friendship Bridge and for Itaipu. Buses come every 20 to 30 minutes and thin out after 10pm. Uber and 99 work well and are the practical answer to the city's real distances: downtown to the park is 25 km, and downtown to Itaipu is 12 km in the opposite direction. The city is flat, with bike lanes on Av. das Cataratas and Av. Tancredo Neves, but the heat and the distances make cycling something for your own neighborhood, not for sightseeing. International taxis and vans cross to Puerto Iguazú (about 20 km) and Ciudad del Este (about 8 km), and wait while you get stamped when you need to.

Foz do Iguaçu is a border city with border-city problems, but visitors spend almost all their time in well-policed tourist areas (the national park, Rodovia das Cataratas, Itaipu, Marco das Três Fronteiras) where the real risk is low. Outside them, the precautions depend on time and place. Bag and phone snatching happens downtown and in the crowds on the Friendship Bridge, especially on busy days; a parked car with luggage in view is a problem in Vila Portes and Porto Meira; and downtown empties after 6pm when the shops close, so at that hour use a ride-hailing app instead of walking. On the Paraguayan side, the shops of Ciudad del Este are open from 7am to 5pm and empty fast: avoid carrying visible shopping bags when walking back across the bridge, and don't accept “help” from middlemen offering currency exchange or a priority line. There are three common scams: made-up exchange rates at the booths on the bridge, fake guides selling park tickets in the parking lot, and taxis without meters charging double for the international ride, so agree on the fare first or use an app. Inside the park the risk is natural: don't go past the railings, don't get into the river, and bring insect repellent. Emergency numbers: 190 (police), 192 (Samu ambulance), 193 (fire department).

Don't say thanks over tereré

In the circle, handing back the cup in silence keeps your turn; saying “thank you” gives it up.

Ask the currency before paying

On the Paraguayan and Argentine side, the final price depends on the currency chosen at the counter.

Crossing the border isn't “international travel”

For locals, going to Ciudad del Este or Puerto Iguazú is like going to the next neighborhood over. Treating the crossing as an exotic adventure sounds odd; “I'm just popping over to Paraguay” is what everyone says.

Don't feed the coatis

The park's coatis come up to anyone holding food, and they scratch and bite; feeding them gets you a fine. Keep your snack in a closed backpack and don't take photos with food in your hand.

Haggle in the arcades, not in shops with price tags

In the street markets and arcades of Vila Portes and Ciudad del Este, negotiating price and quantity is part of the deal. In a mall, supermarket, or restaurant, the price is the price.

Respect lunch hours

Many restaurants serve from 11:30am to 2:30pm and close in the afternoon, and border shops open early, at 7 or 8am. Showing up at 3pm for lunch usually ends at a snack bar.

Seeing only one side of the falls

Assuming both sides of the falls are the same and seeing only one. From Brazil, the panorama takes 2 to 3 hours on the trail; from Argentina, you walk above the water, beside most of the falls, and the visit takes a full day. If you have two mornings, use one on each side.

Same-day ticket and arriving at noon

Buying your ticket on the spot and showing up at noon. The Brazilian park sells by date and time slot, and high-season morning slots sell out. Since the line for the internal bus is longest between 11am and 2pm, buy the day before and pick the first slot.

Downtown to the park is 25 km

Underestimating the distances. Downtown to the park is 25 km, to the airport 11 km, and to Itaipu 12 km in the opposite direction: trying to fit in the falls in the morning, Itaipu in the afternoon, and Argentina the same day usually knocks one of the three out.

Crossing the border without checking stamp rules

Crossing the border without checking the stamp requirement. Brazilians use an ID card to enter Argentina and Paraguay, but foreigners from outside Mercosur have to stop at the Federal Police and the other country's immigration, and since April 10, 2025, citizens of the US, Canada, and Australia need an electronic visa to re-enter Brazil. Confirm the current rule before you travel.

US$500 per person every 30 days

Blowing past the shopping allowance. Brazil's overland duty-free allowance is US$500 per person every 30 days. Above that, customs charges tax on the way back, and enforcement on the BR-277 and at the airport happens routinely, year-round.

“Vou ali no Paraguai” (vo a-LEE noh pa-ra-GWY)

Crossing the Friendship Bridge and coming back the same day: the standard phrase for a trip to Ciudad del Este

“Do lado de lá” (doh LA-doh jee LAH)

Argentina or Paraguay, depending on context; the country's name is almost never said out loud

“Bora tomar um tereré?” (BOR-ah toh-MAR oom te-re-RE)

An invitation to the cold yerba mate circle; saying yes is the norm, and the cup always circulates the same direction

“Mba'éichapa” (Guaraní; mba-EI-cha-pa)

“How's it going?”: a greeting used by Paraguayans on both sides of the border

“¿Cuánto sale?” (Spanish)

“How much is it?”. The question that opens any purchase in Ciudad del Este or Puerto Iguazú

“Aceita real?” (a-SAY-ta he-AL)

The obligatory question on the Paraguayan and Argentine side: the answer is usually yes, at a worse rate than the official exchange

The two rivers and the basalt step

Foz do Iguaçu sits on a spit of land between two rivers: the Paraná, which runs north-south and separates Brazil from Paraguay, and the Iguaçu, which comes from the east (rising 60 km from Curitiba and running 1,320 km) and separates Brazil from Argentina before flowing into the Paraná, 23 km below the falls. The terrain is a low basalt plateau, between 150 and 250 m in elevation, formed by Cretaceous lava flows (about 130 million years ago) that stacked hard rock over soft rock; where the Iguaçu meets that basalt step, the river opens into a 2.7 km front and drops in about 275 falls, up to 80 m at the Devil's Throat. Average flow is about 1,500 m³/s, but in floods like June 2014 it topped 45,000 m³/s, and in prolonged droughts it drops below 500 m³/s.

The city 25 km from the water

Downtown Foz lies 25 km from the falls, on a grid of wide avenues inherited from the Itaipu boom, with Av. Brasil and Av. Juscelino Kubitschek as its main axes. The BR-277 comes in from the east, the BR-469 (Rodovia das Cataratas) runs down to the park and the airport, and Av. Tancredo Neves heads up to the dam.

The subtropical climate

The climate is humid subtropical (Cfa), with rain year-round (about 1,700–1,800 mm) and summers of 32 to 38 °C.

Layers of immigration stacked up fast

Foz is a city of immigration layers stacked up in a short time. Before 1950 there were already Paraguayans and Argentines; between the 1950s and 1970s came Lebanese and Syrian immigrants, who today run mosques (the Omar Ibn Al-Khattab, from 1983, is the most visible), Arabic schools, and the shops of Vila Portes; in the 1970s and 80s came Chinese and Taiwanese immigrants, who built the Chen Tien Temple in 1996; the Itaipu works brought in people from Rio Grande do Sul, Santa Catarina, and the Northeast, who introduced churrasco, chimarrão, and forró. The municipality counts more than 70 nationalities. The practical result is ordinary and visible: on a single block there's a halal butcher, a currency exchange, a Paraguayan barbershop, and a steakhouse.

UNILA, the Technology Park and the music of Vila Yolanda

Formal cultural life is small for a city this size and revolves around three institutions. UNILA, a federal university created in 2010, brings together students from all over Latin America and fills downtown with spoken Spanish; the Itaipu Technology Park (PTI), set up in the old construction-camp lodgings, has labs, a museum and public programming; and the national park itself funds wildlife research and is the largest indirect employer. Live music is concentrated on Av. Jorge Schimmelpfeng and in the bars of Vila Yolanda, with sertanejo, cover rock and, often, Paraguayan polka and guarania played on the harp.

Amateur soccer and futsal

The strongest local sports are amateur soccer and futsal; the professional team, Foz do Iguaçu FC, plays in the state divisions at Estádio ABC. The religious calendar mixes Catholic Masses, evangelical services, which have grown sharply since the 1990s, Friday prayers at the mosque and Buddhist celebrations at the Chen Tien Temple.

The Mission (1986), by Roland Joffé

Filmed largely at the falls and on the Iguaçu River, it recreates the destruction of the Guaraní Jesuit missions in the 18th century and helps make sense of mission ruins such as San Ignacio Miní.

“Adeus a Sete Quedas” (1982), a column by Carlos Drummond de Andrade

Published in the Jornal do Brasil days before the Itaipu reservoir filled, it's the piece that fixed the price the dam exacted: a set of falls larger than Iguaçu, drowned in October 1982.

El Río Oscuro (1943), by Alfredo Varela

A novel about the mensús of the upper Paraná yerba groves, the basis for the Argentine film Las Aguas Bajan Turbias (1952). It explains who worked this border before there was a city, a bridge, or a dam.
