Iguazu National Park, Argentina

Iguazu is 275 individual waterfalls spread across nearly 3 kilometres of the Iguazu River, and the Argentine side puts you closer to more of them than any other approach. The system straddles the border between Argentina and Brazil, inscribed as two separate UNESCO World Heritage Sites (Argentina in 1984, Brazil in 1986), and the two parks genuinely complement each other rather than duplicate the experience. But the Argentine side is the right place to start: more trails, more waterfalls, and the walkway to the Devil’s Throat above the falls rather than below them.

The Devil’s Throat

The Garganta del Diablo is the centrepiece: the Iguazu River drops 82 metres into a horseshoe-shaped chasm where the noise and spray erase any sense of distance between you and what you are looking at. The walkway extends directly over the lip of the falls and the view is straight down into a white void. It is not comfortable, and that is the point.

The walkway closes temporarily when river levels rise after heavy rain, which happens most often during the January to March wet season. When floods force the closure it can last days or weeks, and there is no advance warning. Check the official park website (iguazuargentina.com) before travelling if you are visiting in that window. The Argentine park closes daily for last entry at 16:30 and the Eco-Train that runs to the Devil’s Throat makes its final departure around 15:30.

The park circuits

The Upper Circuit (Sendero Superior) follows the top edge of the falls and gives panoramic views over the wider system, including Bossetti Falls and the San Martín waterfalls. It is the drier of the two main trails.

The Lower Circuit (Sendero Inferior) goes down to river level, where the scale of the falls is most obvious. The mist soaks you well before you reach the water. A waterproof case for your phone and a light poncho are the two items most visitors wish they had brought.

From the lower circuit, short boat trips run to Isla San Martín, an island in the river with its own viewpoints and resident wildlife. Toucans, plush-crested jays, and coatis are common across all the park trails. The coatis, members of the raccoon family, are habituated to humans and will attempt to take food directly from bags and hands. They bite. Do not feed them or attempt to pet them regardless of how docile they appear.

Argentina versus Brazil

The Brazilian park offers the panoramic view of the full system that appears in most photography. The Argentine park puts you at water level, on top of the falls, and inside the spray zone in ways that Brazil does not. Both are worth a day each. The Brazilian side requires a separate visa for some nationalities and a border crossing, which is straightforward but adds planning time.

Tickets and hours

The Argentine park opens daily at 08:00 and closes at 18:00, with ticket sales ending at 16:30. Current adult admission for foreign visitors is approximately $45,000 Argentine pesos, though Argentina’s inflation means this figure changes frequently: check the official park website for the current price before you go. If you validate your ticket at the exit booth on your first day, you receive a 50% discount on re-entry within 72 hours, which is a worthwhile option if you plan to spend two days on the Argentine side. Children under 6 enter free.

Argentine currency volatility also affects accommodation and restaurant pricing: prices quoted in pesos can shift substantially week to week. Properties that quote in US dollars offer more predictability.

Getting there

The nearest airport is Cataratas del Iguazú International Airport (IGR), about 20 minutes from the park entrance and served by direct domestic flights from Buenos Aires (Aeroparque and Ezeiza). Flight time from Buenos Aires is approximately two hours. Long-distance buses from Buenos Aires also connect to Puerto Iguazú (18 to 20 hours), though the flight makes considerably more sense unless you are doing a full overland route.

From Puerto Iguazú town, taxis and remises to the park gate take about 10 to 15 minutes and cost around $5 to $10 USD at current exchange rates. Buses from the town centre to the park also run regularly.

Where to stay

The Gran Meliá Iguazú, inside the Argentine national park boundary, overlooks the falls directly. Rooms at this tier mean early access to the park before it opens to day visitors and no transport logistics. Rates run from around $400 to $700 USD per night at peak periods. Belmond Hotel das Cataratas on the Brazilian side offers a comparable experience from the other bank.

Puerto Iguazú town, about 20 minutes from the park, has a much wider range of accommodation. Iguazu Jungle Lodge offers comfortable lodge-style rooms surrounded by forest with a large pool, about a 10-minute walk from the centre, from around $120 to $180 USD per night. Hotel Jardin de Iguazú in the town centre suits budget travellers and includes breakfast. Hostel and guesthouse options in town start from around $20 to $40 USD per night for a private room.

Where to eat

The park itself has a restaurant at the visitor centre near the Eco-Train station, which handles the midday crowd reasonably well but is not a reason to visit on its own merits. The Belmond Hotel’s restaurant, Elena, serves Argentine cuisine at a luxury price point.

For better value, Puerto Iguazú town offers a solid range of parrillas (Argentine steakhouses). Parrilla San Martín is the consistent local recommendation for asado, the traditional Argentine slow-grilled meat, with a full meal running around 3,000 to 6,000 pesos per person at current rates. The town’s main street, Avenida Tres Fronteras, has multiple options at varying price points and stays busy in the evenings.

Practical notes

Arrive at the park gate as close to 08:00 as practical. The first two hours of the morning are noticeably cooler, the wildlife is more active, and the main viewpoints are quieter. By 10:30 the coach tour groups begin arriving in volume and the crowd density at Devil’s Throat makes the experience materially worse.

The best season for water volume is April through September (the drier months by South American standards, but the falls run highest from accumulated wet-season rain). Visiting in the Argentine dry season means lower humidity and more comfortable walking temperatures, typically 15 to 25 degrees Celsius, against the wet-season peak of 35 degrees Celsius plus.

Closed-toe shoes with grip are the right call for all trails. Sections of the lower circuit are permanently damp. A waterproof bag for electronics is more useful than a camera rain cover and doubles as general pack protection.

The 72-hour re-entry discount is the most underused practical tip at the Argentine park. If you can allocate two days to the Argentine side, the cost of the second day halves and you will see aspects of the park that a single day does not cover.
