Practical info
Getting There
- Argentine side: Fly to Cataratas del Iguazú Airport (IGR) from Buenos Aires (1.5 hours). Brazilian side: Fly to Foz do Iguaçu Airport (IGU)
- Airport to Puerto Iguazú: taxi ARS 15,000 (20 min). Local buses connect town to both parks. The international bridge has regular bus service
- Long-distance buses connect Puerto Iguazú to Buenos Aires (18 hours, semi-cama ARS 30,000–50,000) — overnight bus saves a hotel night
Border Crossing
- Crossing between Argentina and Brazil requires your passport. Most nationalities get visa-free entry to both countries for day trips
- US citizens need a visa or electronic travel authorization (e-visa) for Brazil — check current requirements before crossing. The e-visa can be processed online
- The border crossing is informal and quick — immigration at the bridge takes 15–30 minutes. Keep your passport accessible throughout the day
Health & Safety
- Yellow fever vaccination is recommended (and sometimes required for onward travel). Dengue and mosquito-borne diseases exist — use repellent constantly
- The heat and humidity are intense — drink 3–4 litres of water daily, wear sunscreen, and take breaks in shade. Heat exhaustion is common among tourists
- Coatis (raccoon-like animals) in the park steal food aggressively and can bite. Never feed wildlife. Keep bags zipped and food sealed
Connectivity
- WiFi in Puerto Iguazú hotels and cafes is reliable. The park has patchy WiFi near the visitor centre only — expect no signal on trails
- Argentine SIM cards (Personal, Movistar) work in Puerto Iguazú. Brazilian SIM needed on the other side — or use WiFi calling
- Download offline maps before visiting. WhatsApp is the primary communication tool on both sides of the border
Money
- Argentina: bring USD cash for the blue rate. Brazil: cards widely accepted in Foz. Paraguay (Ciudad del Este): USD cash preferred
- Argentine park accepts cash and cards. Brazilian park accepts cards (R$). Keep both currencies if crossing the border
- Tip 10% in Argentine restaurants (not included). In Brazil, 10% service charge is usually added. Check the bill before adding more
Best Time & Weather
- March–June and August–November offer the best balance of water flow and weather. July can be cool. December–February is hot, humid, and crowded
- High water (May–July) makes the falls more powerful but can close boardwalks. Low water (August–October) reveals more individual cascades and allows Isla San Martín access
- Rain is common year-round — bring a light rain jacket. You will get wet from spray regardless, so embrace it from the start
Cultural tips
Two Sides, Two Experiences
The Argentine side puts you inside the falls with close-up boardwalks and jungle trails. The Brazilian side gives you the panoramic view of the entire horseshoe. You need both sides for the complete experience — budget at least one day for each.
Atlantic Forest Biodiversity
Iguazú protects one of the last fragments of the Interior Atlantic Forest — one of the most biodiverse and endangered ecosystems on Earth. Over 2,000 plant species, 400 bird species, and jaguars still roam here. The forest is the real treasure — the falls are its dramatic centrepiece.
Mate & Tereré
On the Argentine side, drink hot mate. Cross to Brazil or Paraguay and everyone drinks tereré — cold mate with citrus juice. In the subtropical heat, tereré makes more sense. Accept whichever is offered — both are social rituals of friendship.
Amethyst & Gemstones
The Iguazú region sits on one of the world's largest basalt formations containing amethyst geodes. Local markets sell genuine amethyst, agate, and quartz at fair prices. Small geodes make excellent souvenirs — they are the real thing, not tourist fakes.
Three Countries Converge
Argentina, Brazil, and Paraguay meet at Iguazú. Each side has a different language, currency, and culture but shares the same river and forest. The tri-border area has been a meeting point for Guaraní peoples for thousands of years before any national boundary existed.
Full Moon Walks
Five nights per full moon cycle, the Argentine park opens for guided moonlight walks to Devil's Throat. The falls illuminated by moonlight — no artificial lights — is one of the most magical experiences in South American travel. Check the calendar and book weeks ahead.
