Iguazu Falls: Argentina or Brazil First?

Do both. That is the practical answer, and most people who visit only one side leave wondering what they missed. The two national parks are operated independently, require separate entrance fees, and offer fundamentally different experiences. Skipping either is a genuine mistake when you have come this far.

The Argentine Side: Inside the Falls

The Argentine side puts you inside the falls rather than across from them. The Upper and Lower Circuit trails bring you within metres of the spray. The Devil’s Throat (Garganta del Diablo) is the centrepiece – a U-shaped canyon where 14 separate cataracts converge and drop 82 metres into unstructured chaos. A small train runs from the park entrance to the Devil’s Throat platform; the walk alone is roughly a kilometre through riverine forest.

Entry for international visitors runs around USD 40 in 2026, though Argentine peso-denominated pricing shifts with the exchange rate – check the official park site before you go. The full circuit, both upper and lower, takes about half a day at a reasonable pace. Allow more time if you stop to watch the water properly.

Coatis – small raccoon-like animals with pointed snouts – are everywhere on the trails. They look charming and they are genuinely bold. They will push into your bag for food. They bite when startled. Keep anything edible secured.

The Brazilian Side: Understanding the Scale

The Brazilian side gives you the panoramic view. A 1.5-kilometre elevated walkway runs along the canyon rim with the full wall of falls across from you, and the scale becomes comprehensible in a way it simply does not on the Argentine side, where you are always too close to see the whole picture. The walkway ends at a platform directly over the river below the Devil’s Throat.

Entry runs around USD 18 to 20 for most international visitors. The Brazilian Macuco Safari boat ride takes you directly under the main falls. You will get completely soaked. This is the point of the excursion and not a side effect.

The Brazilian side takes roughly 3 to 4 hours including the boat trip. You can cross from the Argentine side as a straightforward day trip.

Where to Stay and How to Base

Puerto Iguazu on the Argentine side is the better base for most visitors. It is cheaper than Foz do Iguacu by 15 to 25 percent for comparable accommodation, has a pleasant restaurant strip along Avenida Cordoba, and puts you at the Argentine park entrance within 20 minutes. Hotels at every price point are available here.

The Belmond Hotel das Cataratas sits inside the Brazilian national park itself and lets guests visit the falls at dawn before other tourists arrive. The access alone justifies the price for some people. For anyone staying there, the early morning visit when the mist is still rising and the walkways are empty is genuinely something different from the midday experience.

Foz do Iguacu on the Brazilian side also has an international airport, and if you are flying in from Sao Paulo or Rio it may be the more convenient arrival point.

Getting There

Puerto Iguazu has an international airport with flights from Buenos Aires (Aeroparque) taking about 1.5 hours. The Argentina-to-Brazil crossing is by a short bus ride across the Tancredo Neves bridge. The border crossing is usually straightforward but not instantaneous; allow an hour including passport control.

Practical Notes

April through May and August through September offer the best weather and manageable crowds. July is school holiday season in Argentina and Brazil and the parks are noticeably busier. Buy tickets online in advance – the Argentine park in particular runs a timed-entry system in peak periods and walk-up availability at busy times is not guaranteed. The falls run highest in March and April after the southern hemisphere summer rains, which also means more spray, more noise, and better photographs.
