Which side of Iguazu Falls is better — Argentina or Brazil?

Both sides are worth visiting if you have the time. The Argentina side puts you right on the catwalks above and beside the falls, including the Devil's Throat walkway — immersive and dramatic. The Brazil side offers a single sweeping panoramic walkway that lets you see the full scale of the falls in one view. Most visitors who do both prefer the Argentina side for the experience, but the Brazil side for the best photograph.

Which airport to fly into for Iguazu Falls?

IGR (Cataratas del Iguazú) serves the Argentina side and is closest to the national park entrance. FIG (Foz do Iguaçu) serves the Brazil side. You can fly into one and out of the other if visiting both sides, which avoids backtracking. Buenos Aires (AEP or EZE) and São Paulo (GRU) have the most frequent connections to both airports.

Will I get wet at the Devil's Throat?

Yes, completely. The Devil's Throat walkway ends at a viewing platform positioned directly above the largest and most powerful section of Iguazu Falls. The mist and spray at the viewing platform is so intense that even a heavy waterproof jacket will not keep you fully dry. Pack a waterproof phone case, put electronics in a dry bag, and accept that getting drenched is part of the experience.

Carry-On Packing List for Iguazu Falls: Argentina & Brazil

Q: What to pack for Iguazu Falls?

Waterproof shoes or sandals you don't mind soaking, quick-dry clothing, a waterproof phone case or dry bag, and sunscreen. A lightweight waterproof jacket is useful for the spray, though you will get wet regardless. Breathable fabrics are essential — the subtropical humidity is intense.

Iguazu Falls is one of the most overwhelming natural spectacles on Earth. Wider than Victoria Falls and taller than Niagara, the falls stretch nearly 3 km across the border between Argentina and Brazil, with up to 275 individual cataracts dropping between 60 and 82 metres into the canyon below. On a high-water day, the sound is audible from kilometres away.

The falls sit where the Iguazu River plunges off the edge of the Paraná Plateau. Both sides sit within national parks — Iguazú National Park on the Argentina side and Parque Nacional do Iguaçu on the Brazil side — both UNESCO World Heritage Sites.

Getting There: Airports and Connections

Airport	Code	Side	Connections
Cataratas del Iguazú	IGR	Argentina	Buenos Aires AEP (1h 50m), EZE (2h)
Foz do Iguaçu	FIG	Brazil	São Paulo GRU (1h 50m), Curitiba CWB

IGR is a small regional airport about 20 km from the park entrance. It handles Aerolíneas Argentinas and LATAM flights from Buenos Aires. FIG is slightly larger, served by GOL, LATAM, and Azul from São Paulo and other Brazilian cities.

A practical approach: fly into IGR, spend two days on the Argentina side, then cross the border by bus to see the Brazil side, and fly out from FIG — or reverse the route. The international crossing adds time but avoids backtracking.

Note on carry-on limits: Aerolíneas Argentinas domestic allows one carry-on up to 55 × 35 × 25 cm at 8–10 kg. LATAM Argentina allows 55 × 35 × 25 cm at 8 kg. GOL Brazil allows 35 × 25 × 55 cm at 10 kg.

Argentina Side: Iguazú National Park

The Argentina side rewards a full day, ideally two. The park has two main walkway circuits:

Upper Circuit (Circuito Superior): A 1.1 km loop over the top of several falls. You look down into the cascades from above. Relatively dry — manageable in regular shoes.

Lower Circuit (Circuito Inferior): A 1.7 km loop that takes you to the base of the falls and onto a boat dock for optional river tours. You will get spray-wet on this circuit, especially near Salto Bosetti and Salto Dos Hermanas.

Devil's Throat (Garganta del Diablo): This is the centrepiece — a 1.2 km catwalk out to a platform positioned directly above the largest single section of falls. The roar is extraordinary. The spray is total. Put everything electronic in a waterproof bag or case before you start walking. You will be soaked by the time you reach the platform. Bring a change of clothes if you plan to eat at the park restaurant afterwards.

A free shuttle train runs between park zones. Allow a full day minimum for the Argentina side.

Brazil Side: Parque Nacional do Iguaçu

The Brazil side has a single main walkway of approximately 1.2 km that runs along the canyon rim, giving a sweeping panoramic view of the full sweep of falls across to the Argentina side. The scale becomes immediately apparent — you see Iguazu as a whole rather than from within it.

The Brazil side is less immersive but better for photography and understanding the geography. The walkway ends at a viewing deck very close to the water, where spray provides a refreshing shower on hot days. A catwalk extends over the water at the end — this section gets wet.

Boat tours on the Brazil side take you directly under the falls. If you do one, assume you will be completely soaked.

Climate: Subtropical and Humid

Iguazu is subtropical. Summer (December to February) is extremely hot and humid — temperatures regularly exceed 35°C with heavy afternoon rain. This is also the highest-water season, making the falls most powerful but conditions most demanding for visitors.

The best visiting seasons are April to October, with May, June, and July offering pleasant temperatures of 18–25°C and less humidity.

Season	Months	Conditions
Summer	Dec–Feb	30–38°C, high humidity, afternoon storms
Autumn	Mar–May	20–28°C, moderate humidity, good water levels
Winter	Jun–Aug	15–22°C, low humidity, comfortable
Spring	Sep–Nov	Warming rapidly, building humidity

The falls are at their most spectacular after heavy rain — water levels can triple after storms in the watershed upstream. Argentine winter can occasionally see lower water levels.

What to Pack for Iguazu Falls

Waterproofing is the entire strategy:

Waterproof phone case — a dry bag sleeve or case is essential, not optional. Your phone will get soaked at the Devil's Throat. A rigid waterproof case provides the best protection.
Dry bag or waterproof daypack liner — bring a small dry bag (5–10 litre) for the park. Roll your valuables inside it within your regular daypack.
Water-resistant sandals or waterproof shoes — you will walk through puddles, mist, and direct spray. Flip flops work but a sport sandal with grip (like Chacos or Tevas) is better on wet surfaces. Do not wear leather shoes or shoes you cannot get completely wet.
Quick-dry clothing — synthetic fabrics only. Cotton takes hours to dry in the humidity and feels miserable when wet.
Lightweight waterproof jacket — useful for the spray sections, though it will not keep you dry at the Devil's Throat. Doubles as a wind layer in winter.
Change of clothes — keep dry clothes in your hotel bag or a sealed plastic bag in your daypack. Changing after the Devil's Throat walkway is genuinely appreciated.

Comfort in the heat:

Light breathable shorts and t-shirts in summer
Lightweight trousers in winter — mornings can be cool
Sunscreen (the park has significant exposed sections — even on overcast days UV is high)
Hat with a brim
1.5 litres of water minimum per person — park vendors exist but are expensive

Border Crossing: Argentina to Brazil

Many nationalities can cross freely on a day trip. Carry your passport at all times — the border checkpoint is on the road between the two parks. Some nationalities require visas for Argentina, Brazil, or both. Check the requirements for your passport well before travel.

The most common crossing route is a taxi or bus from Puerto Iguazú (Argentina side town) across the Tancredo Neves Bridge to Foz do Iguaçu (Brazil side town). The crossing takes 20–40 minutes including passport control.

Bottom Line

Iguazu Falls is one of the few destinations that genuinely exceeds expectations. Pack light, waterproof, and quick-drying. Protect your phone. Accept that getting soaked at the Devil's Throat is not a risk but a certainty — and one of the best travel experiences in South America.
