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.
