What should I know before visiting Iguazu Falls?

Direct answer

Iguazú Falls spans the Argentina–Brazil border and is best planned as a 1–3 day visit. Know visa/entry rules for both countries, choose the right season, use recommended transport, respect safety rules, and prepare for wet conditions and insects.

Visa & entry requirements

• Check passport validity (usually at least 6 months). Requirements vary by nationality.
• Many nationalities enter Argentina and Brazil visa-free for short tourist stays; others need visas or electronic authorizations (e.g., Brazil’s e-visa/electronic travel authorizations when required).
• If you plan to visit both sides, ensure you have the right to enter both countries (separate stamps/controls).
• Bring printed copies of onward/return tickets and accommodation details; immigration can ask for them.

Best time to visit

• High water/most impressive falls: November–March (warm, heavy flow).
• Best weather/fewer insects: April–May and August–October (milder temps, lower crowds).
• Rainy season (Dec–Feb) increases flow but also humidity, mosquitoes, and occasional park closures after storms.

Safety tips

• Stay on marked trails and observation platforms; barriers are there for a reason.
• Beware of slippery surfaces—wear grippy, quick-dry shoes.
• Protect gear from spray (waterproof bags/covers) and bring a dry change of clothes.
• Watch for strong currents in rivers; swimming is prohibited.
• Keep valuables secure; petty theft can occur in tourist areas.
• Follow ranger instructions and check park alerts for closures or weather warnings.

Local customs & etiquette

• Brazilians and Argentines are warm; greetings often include a handshake or light cheek kiss in social settings.
• Spanish is spoken on the Argentine side; Portuguese on the Brazilian side. Learn basic phrases: hello, please, thank you.
• Tipping: restaurants typically add 10% service; leaving small change or rounding up is appreciated for guides/drivers.

Currency & money

• Argentina: Argentine peso (ARS). Brazil: Brazilian real (BRL).
• Credit cards widely accepted in town; cash is useful for small purchases and border/park vendors.
• ATMs available in Puerto Iguazú (Argentina) and Foz do Iguaçu (Brazil), but carry some cash—machines can run out.
• Prices on the Brazilian side often quoted in BRL and sometimes USD; scanning card fees/cash withdrawal fees may apply.

Transportation & getting there

• Nearest airports: Cataratas del Iguazú International (IGR) on the Argentine side; Foz do Iguaçu/Cataratas (IGU) on the Brazilian side. Flights from Buenos Aires, São Paulo, and other regional hubs.
• Bus: regular services connect Puerto Iguazú and Foz do Iguaçu to airports and regional cities.
• Driving: both parks have parking; renting a car is feasible—carry passport and insurance, be aware of border-crossing rules for rental companies.
• Transfers: many travelers use hotels, tour operators, or taxis to reach park entrances.
• Inner-park transport: both parks have trains/shuttles and walking circuits. Allow time—queues can be long in high season.

Must-know tips & local insights

• Plan time: Argentina’s side (Iguazú National Park) offers extensive trails and close-up views, including the Garganta del Diablo (Devil’s Throat). Brazil’s side provides panoramic, postcard views—visit both if you can.
• Buy tickets in advance online when possible to avoid lines. Consider multi-day or combined entry passes.
• Guided tours: choose certified guides for boat rides (e.g., Macuco Safari on Brazil side, Gran Aventura on Argentina) and boat-walk safety briefings. Boat rides get you drenched—waterproof gear and phone protection required.
• Time of day: early morning or late afternoon for fewer crowds and better light for photos.
• Wildlife: expect coatis (on the Argentine side), toucans, butterflies—you may be asked not to feed animals.
• Food & facilities: restaurants and kiosks near entrances; consider packing snacks and water for long trail days.
• Border crossing: if you cross the border by land, allow extra time for immigration. Some excursions depart one country and return to the other—confirm logistics and re-entry requirements.
• Health: bring insect repellent, sunscreen, a light rain jacket, and rehydration items. Check routine vaccinations and any travel advisories.

Quick checklist

• Passport, visas/eTA if required
• Local currency and card
• Waterproof case for phone/camera
• Quick-dry clothing, waterproof jacket, good shoes
• Insect repellent, sunscreen
• Printed/phone copies of bookings and IDs
• Plan 1–3 days to see both sides

Enjoy the falls—respect park rules, be prepared for spray and humidity, and aim to see both the Argentine and Brazilian perspectives for the fullest experience.
