Iguazú Falls with Families: A British Guide

Iguazú is the destination British families in Argentina end up doing in their first year, and rightly so. It is a two-hour flight from Buenos Aires, a two-day visit minimum, and one of the genuine wonders of the world. The logistics are simple, the experience is overwhelming, and even teenagers who claim to be too cool will be silenced by the Garganta del Diablo.

This is what we learned from doing it with two children (then 5 and 7) and from going back twice since with various visiting friends and family.

Getting There

Aerolíneas Argentinas, FlyBondi, JetSmart, and LATAM all fly Buenos Aires (Aeroparque) to Puerto Iguazú in 1h45-2h00. Book 6-8 weeks ahead for the best fares; expect ARS 80,000-180,000 return per person (£55-120) depending on season and how late you book.

The airport is 25 minutes from the town centre and 30 minutes from the National Park entrance. Pre-book a transfer or take a taxi — Uber works in Iguazú but coverage is patchy.

How Long to Stay

Three nights is the sweet spot. Two nights feels rushed; four starts to be too much falls (and the town itself is small). The classic itinerary:

• Day 1: Arrive afternoon, check in, dinner in town, early night.
• Day 2: Argentine side. Full day in the park.
• Day 3: Brazilian side. Half day, plus afternoon for the bird park (Parque das Aves) and pool.
• Day 4: Morning flight back.

If you only have two nights, prioritise the Argentine side over the Brazilian.

Where to Stay

Three meaningful tiers:

The Sheraton Iguazú (inside the park). The only hotel inside the Argentine park, on the lip of the falls. Wake up to mist rising over the Garganta. Easy access to the trails first thing before the day-trip crowds arrive. Expensive (USD 400-700/night for a family room) but if you can afford one splurge in Argentina, this is the right one. Book 3-6 months ahead.

Loi Suites Iguazú or Mercure Iguazú Iru (Puerto Iguazú). Solid 4-star options in town, USD 150-280/night for a family room, with pools (essential after a sweaty day at the falls), buffet breakfast, and shuttle to the park. Best balance of comfort and price.

Garden Stone or El Pueblito Iguazú (budget). USD 80-140/night for a family room. Good basic option if you are watching the budget. Walkable to the town's restaurants.

The Brazilian-side equivalent (Hotel das Cataratas, inside the Brazilian park) is also stunning but requires a Brazilian visa for British passport holders (still required as of early 2026 — check current status).

The Argentine Side: How to Do It

Buy tickets in advance at iguazuargentina.com — at the gate they often sell out by mid-morning in high season. Foreign-resident price (with DNI/precaria) is significantly lower than the tourist price; bring your DNI to the desk to get the local rate.

The park has three main circuits and they take a full day done together:

1. Garganta del Diablo train and walkway (do this first, before 11am if you can). The little Tren Ecológico from the entrance takes you to the start of a 1.1km metal walkway over the river. The walkway ends at the lip of the Garganta del Diablo — the throat of the devil — where the river drops 80m in a single curve. You will be soaked. The kids will be silent. 90 minutes round trip.

2. Upper Circuit (Circuito Superior). 1.7km looped walkway along the top of the falls, with view points down each cascade. Easy walking, all flat metal walkway, suitable for buggies. 75-90 minutes.

3. Lower Circuit (Circuito Inferior). 1.4km along the base of the falls. Steeper and with stairs (not buggy-friendly). The Gran Aventura boat ride launches from the bottom of this circuit. 90 minutes plus boat add-on.

The Gran Aventura boat ride (the famous "go right under the falls" experience). Suitable for ages 6+. Younger children can do the milder Macuco Safari instead. Expect to be soaked through. Bring a change of clothes and a dry bag for phones. Roughly USD 65 per person, book at the dock or in advance.

The Brazilian Side: Half a Day

The Brazilian side gives you the panoramic views the Argentine side cannot. One main 1.2km walkway along the river, ending at a viewing platform that puts you face-on with the Garganta del Diablo from the front. You will need 3-4 hours including the bus into the park, the walk, and the bus out.

Practical: at the moment, British passport holders need a Brazilian e-visa. Apply at vfsglobal.com 2-4 weeks ahead. Check the current status — the visa requirement has been on and off for years.

If you cannot or will not do the Brazilian visa, the Argentine side alone is enough. You will not feel cheated.

What to Bring

• Waterproof bag for phones, wallets, passports
• Quick-dry clothes for the boat ride (you will be properly drenched)
• Trainers or hiking sandals with grip — the metal walkways get slippery
• Sun cream factor 50 and hats — there is little shade
• Mosquito spray for evening walks in town
• Refillable water bottle — the park has water fountains
• Cash in pesos for the smaller stalls and the train

The Bird Park (Parque das Aves)

On the Brazilian side, immediately outside the park entrance. A genuinely worthwhile add-on if you have done the Brazilian-side visit. Walk-through aviaries with toucans, macaws, and the giant harpy eagle. The kids will be in heaven for 90 minutes. USD 30 per adult, USD 15 per child.
