🏢 1. Terminal, Layout & Where the Airport Actually Sits

IGR is a single-terminal airport, and that single terminal is small enough to walk end to end in under three minutes. There is one asphalt runway, 13/31, running 3,300 m — long enough to take the Boeing 737s and Airbus A320s that Aerolíneas Argentinas, Flybondi and JetSmart fly in from Buenos Aires. Everything happens under one roof: check-in, a modest security line, a handful of gates numbered low, one café-bar landside, and the lounge airside in front of gate 1. Operator Aeropuertos Argentina 2000 runs it as part of the national concession.

Geography, reconciled. The conflicting numbers floating around online confuse people, so here is the layout in one sentence: the airport sits on the highway between Puerto Iguazú and the national park, 16 km southeast of the town and only 6 km south of the falls themselves. That means the park entrance is closer to the airport than the town is — about 15 minutes’ drive versus 20–25 minutes into Puerto Iguazú. If your hotel is in town you drive away from the falls to reach it; if you are going straight to the park, you are almost there on landing.

The flight pattern is overwhelmingly domestic. As of early 2026 there are about 72 flights a week between Buenos Aires and Puerto Iguazú, split across the two Buenos Aires airports — Aeroparque (AEP), the close-in city airport, and Ezeiza (EZE), the international one 35 km out. Aerolíneas Argentinas also flies regional Argentine routes here: Córdoba, Rosario, Salta, San Salvador de Jujuy, Tucumán. The cross-border picture is thin — Flybondi’s Lima route is ending 5 June 2026, which leaves the airport effectively domestic again. If you are arriving from outside Argentina, you are almost certainly connecting through Buenos Aires, and you should budget for the AEP-EZE transfer if your inbound international flight lands at Ezeiza and your Iguazú flight leaves from Aeroparque.

The “international” in the name is mostly geographic. IGR is the easternmost Argentine airport with scheduled service, planted at the tri-border, but in 2026 it functions as a domestic gateway with the falls as its entire reason for being. Do not expect a sprawling international concourse. Expect a regional terminal that empties out between the morning and evening Buenos Aires waves.

One genuine 2026 change: the loss of Flybondi’s Puerto Iguazú–Lima link on 5 June 2026 removes the airport’s only regular non-Argentine scheduled route, pushing it back to a purely domestic schedule. If you were counting on a direct Peru connection, that window closes in June.

🛂 2. Visa, Currency Reality & the Yellow-Fever Question

Entry is easy. Citizens of the United States, Canada, the United Kingdom, the European Union, Australia, Japan and South Korea — over 80 nationalities in total — enter Argentina visa-free for up to 90 days. There is no electronic pre-registration, no ETA, no app. The old US$160 reciprocity fee was scrapped in 2016 and has not returned. You present your passport at immigration and you are in. Need longer? Extensions of a further 90 days are handled at the Dirección Nacional de Migraciones for a fee in the low thousands of pesos — verify the current amount before you rely on it.

The health-insurance rule, stated honestly. Since 1 July 2025, Argentina’s rules require non-resident visitors to carry valid travel medical insurance covering hospitalisation and emergency evacuation, declared on entry. In practice, enforcement at borders has been close to non-existent through early 2026 — traveler reports consistently say agents at Ezeiza and overland crossings have not been asking for proof. Treat it as a rule that exists on paper and could be enforced at any time: carry a policy, because the cost of a hospital bill without one dwarfs the premium, but do not expect a desk check.

Currency — read this part carefully, because most guides are out of date. Argentina spent years with a notorious split between the official rate and the “blue dollar” street rate, where paying cash USD could save you 50–80%. That era is over. In April 2025 the Milei government lifted most currency controls under a US$20 billion IMF agreement, and the rates converged hard. As of late May 2026 the official rate sits around 1,410 ARS to the dollar, with the MEP and informal “blue” rates only a few percent away — all three clustered roughly 1,430–1,460. The arbitrage that justified carrying a thick envelope of hundred-dollar bills has collapsed.

What that means for how you actually pay in 2026: use your foreign Visa or Mastercard for most things. Card transactions now settle close to the favorable MEP-equivalent rate, with none of the risk of carrying cash. Keep a modest float of US$200–400 in clean, undamaged USD bills for the gaps — taxi drivers who prefer cash, restaurant tips (which cannot be added to a card slip in Argentina), small purchases, and the occasional vendor without a card terminal. Western Union remains a way to pull pesos at a competitive rate if you want local cash, but the days of cash USD being dramatically better than a card swipe are gone. Do not let a 2022-era blog talk you into changing money on the street.

Argentine peso, the practical version. Notes in circulation run from 1,000 up through 2,000, 10,000 and 20,000 pesos — the larger denominations are recent additions forced by inflation, which is exactly why a coffee can cost a five-figure number. Coins are effectively dead; nobody uses them. ATMs at IGR and in Puerto Iguazú dispense pesos but cap withdrawals low and charge stiff per-transaction fees, so a card-first approach saves you from feeding the ATM repeatedly.

Yellow fever — recommended, not required. Iguazú is in Misiones, a province where yellow fever transmission is possible, so vaccination is recommended for travelers spending time in the area. It is not, however, legally required to enter Argentina, and you will not be asked for a certificate on a domestic arrival from Buenos Aires. The one place a certificate genuinely matters is onward travel: some countries require proof of yellow-fever vaccination if you are arriving from a risk zone, so if Iguazú is a leg in a longer trip, check your next destination’s rule. Get the shot at least 10 days before travel for it to be effective.

🚆 3. Transport — Taxi, Río Uruguay Bus, Rental, Rideshare

The airport-to-town corridor is short and there are four ways to cover it. Prices below are dated to May 2026 and should be confirmed before you travel.

Official taxi — the default. A taxi from IGR to Puerto Iguazú runs roughly US$20–25 (paid in pesos at the equivalent, or in USD if the driver agrees) for the 16-km, 20–25-minute run into town. Going the other way to the national park is shorter — about 6 km, 15 minutes — and cheaper. Book at the desk inside the terminal before you walk out to lock a fixed rate; the booths quote per vehicle, not per person, so a group splits the cost. If you flag a car outside without booking, agree the price out loud before the doors close. There is no meter, so the number you say is the number you pay.

Río Uruguay bus — the cheap option. The Río Uruguay company runs a public bus between the airport and the Puerto Iguazú bus terminal (Terminal de Ómnibus), roughly hourly, for around US$1–3 — a few thousand pesos. The trip takes about 30 minutes. It is the budget choice and it works, but it runs on its own timetable, not yours: if your flight lands between departures you wait, and it drops at the central terminal rather than your hotel door. For a solo traveler with light luggage and time, it is fine. For a group, a fixed-rate taxi split four ways often beats it once you value the wait.

Private transfer / shuttle — the pre-booked middle. Various operators sell door-to-door shuttle transfers, typically advertised under US$10 per seat on a shared van up to a private-car premium, around 35 minutes to town. The advantage is certainty: a named driver waiting at arrivals with your hotel as the drop. Worth it if you are arriving late or want zero friction; otherwise the desk taxi does the same job.

Rental car — only if you are roaming. Car rental counters operate at the terminal. For the falls alone, a car is overkill — you will park it and take the park’s internal train anyway. A rental earns its keep only if you plan to drive the wider region: the Wanda semi-precious-stone mines 50 km north, the Jesuit ruins at San Ignacio Miní about 240 km south, or self-driving across to the Brazilian side. Argentina drives on the right. Fuel is sold in pesos; cards work at most stations.

Rideshare reality. Unlike Buenos Aires, where Uber and Cabify are everywhere, app-based rideshare coverage at Puerto Iguazú and the airport is thin to non-existent in 2026 — this is a small town, and the licensed-taxi trade holds the airport. Do not land expecting to summon an Uber from the curb. Plan on the official taxi desk or a pre-booked transfer instead.

A note on the park’s own transport. Once you are inside the Argentine national park, getting around is on foot and on the Rainforest Ecological Train (Tren Ecológico de la Selva) — a propane-and-electric narrow-gauge line that carries you from the visitor centre out to the Cataratas and Garganta del Diablo stations. It is included in your park ticket; no separate booking. From Garganta station it is a roughly half-kilometre boardwalk over open water to the lip of the Devil’s Throat.

🛋️ 4. Lounges — One Lounge, Named Honestly

IGR has exactly one lounge, and it is worth being plain about that: there is no Aerolíneas-branded premium lounge, no bank-card flagship lounge, no separate first-class space. The single facility is Iguazú by AMAE Lounge, sometimes listed under the older “Aeropuertos VIP Club” name, airside in front of gate 1.

Access and cost. It takes Priority Pass and welcomes walk-up paying customers regardless of airline or class. Walk-in rates start around US$42 per person — steep for a small regional lounge, which makes the math simple: it is good value if you hold a Priority Pass that covers the visit, and questionable value if you are paying cash, given how short most layovers here are and how quickly you can clear this terminal.

What you get. Wi-Fi, a spread of snacks and drinks, wines and some cocktails, and quiet seating away from the gate bustle. It is a comfortable place to wait out a delayed evening Buenos Aires flight. It is not a destination in itself.

The honest verdict. If you are connecting tight or your flight is on time, you may never need it — landside has a café and the airside walk to the gate is minutes. The lounge earns its keep on a long delay or for a traveler whose card grants free entry. Pay US$42 out of pocket for a 40-minute sit and you are overpaying for the convenience.

🍽️ 5. Food & Duty-Free — What to Eat Before You Fly

The airport’s food offer is limited — a café-bar landside, basic options airside, and the lounge if you have access. The real eating is in Puerto Iguazú and at the park, and the price gap between airport and town is the usual one: expect to pay a meaningful premium for anything bought past security versus the same item in town.

The regional plate. Misiones sits on the Paraná, and the river is the menu. Surubí and dorado, two large river fish, turn up grilled or in stews across Puerto Iguazú restaurants — a grilled surubí fillet in town runs a fraction of what an airport sandwich costs. The province is also Argentina’s yerba-mate heartland: mate, the bitter green infusion drunk from a shared gourd through a metal straw, is less a drink than a daily ritual here, and the local chipá — a small, chewy cheese bread of cassava starch, a Guaraní inheritance shared with Paraguay — is the regional snack to actually try. You will see chipá sold from street carts in town for a few hundred pesos; the airport version costs several times more.

Argentine staples, because you are in Argentina. The national obsessions hold in Iguazú: asado (grilled beef), empanadas baked or fried, milanesa (breaded cutlet), and dulce de leche smeared on everything sweet. An alfajor — two soft biscuits sandwiching dulce de leche, often chocolate-coated — is the take-home cookie and the easiest edible souvenir to buy at the airport.

Eateries worth naming. Rather than send you to a specific table I cannot verify is still trading, the reliable move is the strip along Avenida Victoria Aguirre and the streets around the Hito Tres Fronteras in Puerto Iguazú, where the parrillas (grill houses) and river-fish restaurants cluster. Tipping is cash, around 10%, and it cannot go on the card — keep pesos for it.

Duty-free and take-homes. This is a domestic terminal, so do not expect a sprawling duty-free hall; the take-home shopping is Argentine grocery and souvenir fare. The genuinely local buys are yerba mate (a kilo bag of a Misiones brand costs little in a town supermarket and far more in an airport shop), a mate gourd and bombilla straw set, alfajores, and dulce de leche in a sealed jar that will survive the hold. Skip the marked-up airport mate; buy it in town.

💡 6. Insider Tips — The Falls, the Tri-Border & Day-Trips

The decision that defines your trip: Argentina or Brazil. The falls straddle the border, and the two sides are different experiences, not duplicates. Argentina holds roughly 80% of the falls and gives you the immersive day: kilometres of walkways at the water’s edge, the Upper and Lower Circuits, the boat ride to the base, and the Ecological Train out to the Garganta del Diablo (Devil’s Throat) — an 82-metre, horseshoe-shaped roar you stand directly above. Plan a full day. Brazil holds about 20% and gives you the panorama: a single main trail, no more than a couple of hours, that delivers the wide postcard view back across the whole system toward Argentina. The standard advice holds — do both if you have two days, and if you only do one, do Argentina for depth, Brazil for the photograph.

Argentine park, the specifics. Foreigner admission is 45,000 ARS for 2026, paid at the gate; the Ecological Train and all the circuits are included. The park is about 15 minutes from the airport and opens daily — get there at opening to beat the Buenos Aires day-trip crowds to the Garganta walkway, which bottlenecks by late morning. The boardwalk to the Devil’s Throat is roughly half a kilometre each way over open river.

The Brazil-side caveat that changed in 2026. Crossing to Foz do Iguaçu is a 30-km, 40–60-minute run including the border, and the entrance to the Brazilian park (Parque Nacional do Iguaçu) is BRL 117 — about US$21. But the visa rule shifted on 1 January 2026: US, Canadian and Australian citizens now need a Brazil e-Visa (around US$51, valid 10 years, applied for online in advance) to cross — you cannot get it at the border. UK and EU citizens remain visa-free for Brazil. If you are American and you want the Brazilian panorama, sort the e-Visa before you leave home; turning up at the bridge without it means turning around.

Hito Tres Fronteras — the free 20 minutes. At the confluence of the Paraná and Iguazú rivers, Puerto Iguazú’s Hito Tres Fronteras marks the point where Argentina, Brazil and Paraguay meet, each country planting an obelisk in its own colours across the water. Access on the Argentine side is free. It is a short, genuinely interesting stop — you can see three countries at once — and there is a 20-minute light-and-sound show in the evening. It is in town, about 20 minutes from the airport, and costs nothing to look at.

Further afield, if you have the days. The Wanda mines, 50 km north, are open semi-precious-stone workings you can tour, a half-day round trip. San Ignacio Miní, about 240 km south, is the best-preserved of the Jesuit-Guaraní mission ruins, a UNESCO site and a long day-trip or an overnight. Neither is layover material — they are reasons to stay a third day, not detours on a connection.

The layover math, said plainly. Can you see the falls on a layover? It depends on the gap. The park entrance is only ~15 minutes from the airport, but a real falls visit — train out, Garganta boardwalk, a circuit or two — is a half-day minimum. A 3-hour layover cannot do it: by the time you taxi out, pay in, and reach the Garganta, you are turning around. A 6-hour layover technically can reach the Garganta del Diablo and get back, but it is tight once you add the return drive and the security buffer for your onward flight, and it leaves no margin if the train queues. If you have a genuine 6+ hours and travel light, go for the Devil’s Throat and nothing else. Anything shorter, stay airside.

🔧 7. Practical Notes — Connectivity, Currency, Safety

SIM and data. Argentina’s three carriers — Claro, Movistar and Personal — all sell prepaid tourist SIMs, and registration requires only your passport. Claro generally has the most consistent coverage outside the cities, which matters in a region this rural. As of 2026 the local carriers still do not sell tourist eSIMs in-store — you get a physical SIM — but international eSIM providers cover Argentina if you would rather arrive connected. Coverage in Puerto Iguazú and at the falls is solid 4G; deeper in the park it thins out, which is fine because you are there to look at water, not your phone.

Wi-Fi. The terminal has Wi-Fi; the lounge has its own. Town hotels and restaurants are reliably connected.

Currency, restated for the practical moment. Card for almost everything at the favorable rate; a few hundred USD in clean bills for tips, cash-only taxis and small vendors; tips are cash because Argentine card slips will not take them. ATM fees are punishing, so withdraw infrequently and in larger amounts if you must use one.

Tap water. Buenos Aires tap water is safe; outside the capital it is inconsistent, and in a rural province like Misiones the cautious move is bottled or filtered water. It is cheap and everywhere. Do not risk a stomach bug on the day you want to be standing over the Devil’s Throat.

Safety and petty crime. Puerto Iguazú is a tourist town and broadly calm, but ordinary precautions apply: watch your bag at the bus terminal and around the Hito Tres Fronteras, do not flash a wad of pesos or a phone, and use the booked taxi rather than an unmarked car at night. The tri-border region has a reputation for smuggling and informal trade, but that is a business between locals and is not aimed at the falls tourist. Keep your passport secure — you will need it crossing to Brazil.

Tipping. Around 10% in restaurants, in cash. Roughly the equivalent of US$1 per two bags for porters, a similar token for a driver who handles your luggage, and US$10–15 per person to a full-day guide with half that to the driver. None of it goes on a card.
