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

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

IGR is a small regional airport about 20 km from the park entrance. It handles domestic flights from Buenos Aires; check the operating carrier for your date. 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 ceased domestic operations in 2020; confirm the actual domestic operating carrier. GOL permits one 55×35×25 cm main bag up to 12 kg on tickets issued from 14 October 2025, plus a separate 43×32×22 cm personal item up to 10 kg. International Basic excludes the main bag unless purchased; Light includes it. The current table does not offer Basic domestically. Older tickets and charters use a 10 kg main-bag limit; confirm the issued conditions.

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.

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.

LATAM allowance for the booked fare

LATAM permits one main bag up to 55×35×25 cm and 12 kg in Economy, or 16 kg in Premium Economy/Business, plus a 45×35×20 cm personal item. Basic requires a main-bag purchase. Light is included in the English main page and Spanish tables, but the Portuguese international table lists an extra cost; confirm the issued fare. The personal-item FAQ gives 10 kg, while the Brazilian regional table gives 12 kg in Premium cabins.
