How many days at Iguazu Falls? 3 days, one for each side and one for the jungle
By Tony Panopoulos · travel-agency planner in Greece · Updated
Iguazu is about 275 separate waterfalls along almost 3 km of the border between Argentina and Brazil, and the two countries show it in completely different ways. Give it three days, based in Puerto Iguazú: a full day on the Argentine side, where walkways take you right over the edge, half a day on the Brazilian side for the panorama, and time for a boat ride into the spray. The rule that matters: be at the gate at opening time, 8:00, and do the Devil's Throat first.
Short answer
Two days is enough to see both sides: the Argentine park on one day, the Brazilian park and the Itaipú dam or bird park on the next. The third day adds the boat trip, a second look at the Argentine circuits and the jungle trail.
The 3-day plan, day by day
Day 1: Argentine side: the Devil's Throat and the circuits
Morning. Take the Río Uruguay bus from the Puerto Iguazú bus terminal (about 30 minutes, every 20 minutes from 7:00) to Parque Nacional Iguazú, open 8:00-18:00. Foreign visitors pay roughly ARS 45,000-60,000, payable by card. Ride the free Tren de la Selva straight to Estación Garganta and walk 1.1 km over the river to the Garganta del Diablo, where half the river falls 80 metres into a horseshoe of spray.
Afternoon. Return by train to Estación Cataratas and walk the Paseo Superior (Upper Circuit, about 1.7 km), along the top of the falls, and the Paseo Inferior (Lower Circuit, about 1.4 km), which brings you to the foot of Salto Bossetti and Salto Dos Hermanas. Allow 2-3 hours for both.
Evening. Back in Puerto Iguazú, eat grilled surubí (river catfish) or a steak at a parrilla on Avenida Brasil. Expect about ARS 20,000-35,000 per person with wine.
Coatis (ring-tailed raccoon relatives) at the food areas bite and grab bags. Do not feed them, and keep food zipped away.
Day 2: Brazilian side and the bird park
Morning. Cross the Tancredo Neves bridge to Brazil by taxi or tour (about 40 minutes including both border posts) to Parque Nacional do Iguaçu, open from 9:00. Entry for foreigners is around R$100. A double-decker bus takes you to the 1.2 km Trilha das Cataratas, which faces the Argentine falls and ends on a walkway into the base of the Devil's Throat. Bring a rain poncho.
Afternoon. Across the road from the park entrance, the Parque das Aves (about R$90) has walk-through aviaries with toucans, macaws and harpy eagles, many rescued from trafficking. Allow 1.5-2 hours.
Evening. Either eat in Foz do Iguaçu (a rodízio steakhouse costs about R$100-150 per person) or return to Argentina. Cross before late evening: the border is slower after dark and buses stop around 19:00.
Most nationalities need only a passport to cross for the day, but check visa rules; Brazil reintroduced e-visas for US, Canadian and Australian citizens in 2025. Keep your passport stamps, even for a few hours.
Day 3: Boat under the falls and the Triple Frontier
Morning. Go back to the Argentine park and take the Gran Aventura (about ARS 70,000-90,000 or US$70-90): a truck ride through the jungle on the Yacaratiá trail, then a speedboat that drives straight into the spray of the San Martín falls. You will be soaked; bring a dry bag.
Afternoon. Take the free boat to Isla San Martín if the water level allows. Or walk the 7 km round-trip Sendero Macuco through the forest to a small waterfall with a natural pool, the best chance to see monkeys and toucans.
Evening. Walk to the Hito Tres Fronteras in Puerto Iguazú (20 minutes from the centre) for sunset where the Iguazú meets the Paraná and you see Brazil and Paraguay at once. Afterwards, try the Feirinha market for empanadas, cheese and Argentine wine.
The park sometimes holds full-moon walks to the Devil's Throat on five nights around each full moon; tickets are sold at the park and sell out, so ask the day you arrive.
Only have 2 days?
With 2 days, do the Argentine side on Day 1 and the Brazilian side plus the bird park on Day 2, and fit the boat into the first afternoon instead of the Lower Circuit. In one day you can only see one side properly.
Got extra days?
Extra days go to the Itaipú dam near Foz do Iguaçu, one of the largest hydroelectric plants in the world (panoramic tour about R$50-80), to the Jesuit ruins of San Ignacio Miní (about 4 hours south, a UNESCO site), or to the Moconá Falls, which fall sideways along a river.
Where to stay in Iguazu Falls
| Budget | Area | Why | Typical double/night |
|---|---|---|---|
| Budget | Puerto Iguazú centre | Hostels and guesthouses near the bus terminal for the park bus. | ARS 40,000-70,000 |
| Mid-range | Puerto Iguazú, Avenida Tres Fronteras | Pool hotels on the jungle road between town and the falls, quiet and green. | ARS 100,000-180,000 |
| Mid-range | Foz do Iguaçu, Brazil | Bigger town with more choice, closer to the airport and the Brazilian park. | R$300-550 |
| Comfort | Inside the parks | Gran Meliá Iguazú (Argentina) or Hotel das Cataratas (Brazil), with falls views and early access. | ARS 450,000-900,000 |
Getting around
Fly to Puerto Iguazú (IGR) from Buenos Aires Aeroparque (about 1h50), or to Foz do Iguaçu (IGU) from São Paulo or Rio (about 1h30-2h). Overnight buses from Buenos Aires take about 18 hours. Taxis from IGR to town cost roughly ARS 25,000-35,000 (about 20 minutes). The park bus from Puerto Iguazú terminal costs a few thousand pesos each way. Crossing to Brazil, a taxi or remis for the day costs about US$60-90 with waiting time; there is also a cross-border bus to Foz, but you must ask the driver to stop at both immigration posts.
What to eat in Iguazu Falls
On the Argentine side, a parrilla is the default: bife de chorizo, morcilla (blood sausage) and provoleta, with Malbec from Mendoza. The local river fish, surubí and dorado, are served grilled or in a stew. Look for chipá, the cheese bread of the Guaraní region, sold hot at bakeries and street stalls, and drink mate or its cold version, tereré. In Brazil, try a rodízio where waiters bring skewers of meat to your table until you stop them, and pão de queijo with coffee. Inside the parks food is basic and expensive; bring a picnic and water.
Best time to visit
The falls flow all year, but the look changes with rainfall. March to May and August to November have mild weather (20-28°C) and steady water. December to February is hot (often 35°C), humid and rainy, with the most water and the most crowds. June-July is cooler (around 18-22°C) and drier, and Argentine winter holidays fill the parks in July. After heavy rain, the Devil's Throat walkway and the boat trips can close for days.

Approximate 2026 prices in Argentine pesos; Argentine inflation moves peso prices quickly, so check park fees on the official site and expect to pay in reais (R$) on the Brazilian side. Puerto Iguazú charges a small municipal eco-tax per tourist per night, added to hotel bills.
Before you go
Common questions
Which side is better, Argentina or Brazil?
You need both. The Argentine side holds about 80% of the falls and its walkways put you right on top of them, especially at the Devil's Throat; it takes a full day. The Brazilian side is a shorter 1.2 km trail, done in 2-3 hours, that shows the whole panorama of the Argentine falls from across the gorge. If you only have one day, choose Argentina.
Should I pay in pesos, dollars or by card?
Foreign cards in Argentina now get an exchange rate close to the market rate, so paying by Visa or Mastercard is usually fine and the parks accept cards. Carry some pesos for buses, taxis and small restaurants; ATMs charge high fees per withdrawal. On the Brazilian side pay in reais or by card; many places in Foz accept cards for everything.
Will I get wet?
On the Gran Aventura boat ride, completely. At the Devil's Throat and on the end of the Brazilian walkway, you will be sprayed, depending on wind and water levels. Wear quick-drying clothes and sandals with straps, carry a light poncho (sold at the parks for a few dollars) and keep your phone in a waterproof pouch.
Can I see the falls in one day from Buenos Aires?
Technically, with the first morning flight and the last evening flight, but it is rushed and expensive, and flights are often delayed. You would see only the Argentine side. Plan at least two nights in Puerto Iguazú; the falls are best at opening time and in late afternoon light, which a day trip misses.
