The Iguazú Falls (Cataratas del Iguazú) are one of the most spectacular natural wonders on Earth. Located on the border between Argentina and Brazil, the falls consist of around 275 individual waterfalls stretching almost 3 km along the Iguazú River, surrounded by lush subtropical rainforest. The most dramatic section, the Devil's Throat (Garganta del Diablo), is a U-shaped chasm where tons of water thunder down 80 metres into a cloud of mist. The Argentine side, protected by Iguazú National Park (a UNESCO World Heritage Site), offers close-up walkways, jungle trails and boat rides into the falls. The base town, Puerto Iguazú, sits at the Triple Frontier of Argentina, Brazil and Paraguay. This Iguazú travel guide covers the best time to visit, the top things to do, where to stay, how to get there and around, costs, entry rules and practical tips.

Best Time to Visit Iguazú

Iguazú has a humid subtropical climate, with heat and rain throughout the year.

Spring (September–November) and autumn (March–May) are the best times to visit, with pleasant temperatures (20–28°C) and good water levels.

Summer (December–February) is hot and humid, often above 30°C, with heavy rains and high water flow. It's also busy during Argentine and Brazilian holidays.

Winter (June–August) is mild and drier, with temperatures of 15–25°C, but water levels can be lower.

Water levels: The falls' flow varies greatly with rainfall in Brazil and upstream dam releases. After heavy rains, the flow can be enormous, and some walkways or boat trips may close.

Top Things to Do in Iguazú

1. Devil's Throat (Garganta del Diablo)

The most impressive part of the falls. Take the Rainforest Ecological Train to Garganta station, then walk about 1 km along a metal walkway over the river to a platform at the edge of the chasm. Expect to get wet.

2. Upper Circuit (Circuito Superior)

An easy walkway along the top of the falls, offering panoramic views of the cascades.

3. Lower Circuit (Circuito Inferior)

A trail that brings you close to the base of the falls, with views of Salto Bossetti and Salto Dos Hermanas.

4. Gran Aventura Boat Ride

A thrilling jet boat ride up the river and into the spray of the falls. You'll be completely soaked.

5. Macuco Trail

A rainforest trail leading to the Arrechea Waterfall, with chances to see monkeys, coatis, toucans and butterflies.

6. Full Moon Walks

On nights around the full moon, guided night walks to the Devil's Throat offer a magical experience (limited places).

7. Brazilian Side (Foz do Iguaçu)

The Brazilian side offers panoramic views of the whole falls and the Parque das Aves bird sanctuary. Note: citizens of the US, Canada and Australia need an e-visa for Brazil since April 2025; EU and UK citizens don't.

Also worth visiting: the Triple Frontier landmark (Hito Tres Fronteras) in Puerto Iguazú, Güirá Oga wildlife rescue centre, the Itaipú Dam (on the Brazil–Paraguay border) and the Wanda Mines for semi-precious stones.

• Esteros del Iberá: Wetlands with capybaras, caimans and marsh deer.

Suggested 3-Day Iguazú Itinerary

Day 1 – Argentine side (part 1): Arrive early, take the train to the Devil's Throat, then walk the Upper Circuit.

Day 2 – Argentine side (part 2): Walk the Lower Circuit, take the Gran Aventura boat ride and hike the Macuco Trail. (Buy a 2-day pass or get a discount stamp for a second consecutive visit if available.)

Day 3 – Brazilian side: Cross the border to see the panoramic view and visit Parque das Aves.

Wildlife of Iguazú

The subtropical Atlantic Forest around the falls is home to more than 2,000 plant species, 400 bird species and mammals such as the jaguar, tapir, ocelot and capuchin monkey. You'll certainly see coatis, raccoon-like animals that roam the walkways; don't feed them, as they can bite and steal food. Look out for toucans, colourful butterflies and great dusky swifts, which nest behind the waterfalls.

Food in Puerto Iguazú

Try Argentine steak, empanadas, river fish like surubí and dorado, and chipá (cheese bread from the Guaraní region). The Feirinha market in Puerto Iguazú is a lively place for local food, wine and cheese.

Money Tips for Argentina

Argentina's economy has changed rapidly in recent years. Since currency controls were largely lifted for individuals in 2025, the gap between the official and "blue" (informal) exchange rates has narrowed, and paying with an international credit or debit card usually gets a fair rate. ATMs charge high fees per withdrawal and have low limits, so many travellers use cards for most payments and carry a small amount of cash for tips, taxis and markets. Prices in pesos rise frequently, so the figures in this guide are approximate. Always check whether a price is quoted in pesos or US dollars, especially for tours and hotels.

Where to Stay in Iguazú

• Puerto Iguazú: Hotels, hostels and restaurants close to the bus station.
• Inside the park: The Gran Meliá Iguazú offers views of the falls.
• Jungle lodges: Eco-lodges on the road to the park.
• Foz do Iguaçu (Brazil): More hotels across the border.
