Overview
Foz do Iguaçu sits on Brazil's southwestern border with Argentina and Paraguay, home to one of the world's most spectacular natural wonders: the Iguaçu Falls. For UK travellers, it's a bucket-list addition to a wider South American trip, offering thundering waterfalls, dense subtropical rainforest and a genuinely multicultural border city where Portuguese, Spanish and Guaraní are all spoken. There's no direct flight from the UK, so getting here means routing through a major Brazilian hub, but the onward connection is straightforward and well served by the country's domestic carriers.
Best time to fly to Foz do Iguaçu
Foz do Iguaçu has a subtropical climate, so the falls are impressive year-round, but conditions for flying and sightseeing do vary. Winter (June to August) is the most comfortable season for UK visitors, with cooler, drier days around 15-25°C and lower humidity, making it a popular window to travel. Summer (December to February) is hot, humid and prone to heavy downpours, with temperatures regularly topping 30°C, though the falls are often at their most powerful after rain. Shoulder months such as April, May, September and October tend to offer a good balance of pleasant weather and better value fares - see the When to book chart above for how prices move across the year.
Airlines and routes
There's currently no non-stop service between the UK and Foz do Iguaçu (IGU), so every journey involves at least one change of aircraft. British Airways operates a direct flight from London Heathrow to São Paulo Guarulhos (GRU), taking around 11.5 hours, from where domestic carriers LATAM, GOL and Azul run frequent flights of roughly 1 hour 50 minutes onward to Foz do Iguaçu. Alternatively, airlines such as TAP Air Portugal (via Lisbon), Air France (via Paris) or KLM (via Amsterdam) connect through their European hubs to São Paulo or Rio de Janeiro, before a similar domestic hop to IGU. Total journey time from the UK typically runs from around 14 to 18 hours depending on layover length - the price charts on this page make it easy to compare which routing works out cheapest on your travel dates.
Things to do in Foz do Iguaçu
Most visitors build their trip around the falls, but there's more than enough here to fill several days:
- Iguaçu National Park (Brazilian side): Walkways lead right up to the thundering Devil's Throat viewpoint, giving the best panoramic views of the falls.
- Argentine side of the falls: A short border crossing brings you up close to individual cascades via an extensive network of trails and catwalks.
- Itaipu Dam: One of the world's largest hydroelectric plants, with guided tours explaining its engineering and scale.
- Parque das Aves (Bird Park): Walk-through aviaries next to the national park, home to toucans, macaws and other native species.
- Marco das Três Fronteiras: The landmark viewpoint where Brazil, Argentina and Paraguay meet at the confluence of the Iguaçu and Paraná rivers.
At Foz do Iguaçu International Airport (IGU)
Foz do Iguaçu International Airport is conveniently located around 12 miles (18km) from the city centre, and handily sits between the city and the entrance to the national park, so many visitors head straight to the falls before checking in to their hotel. Licensed taxis and ride-hailing apps such as Uber are readily available outside arrivals, with the journey into town taking around 25-30 minutes. Local buses also run between the airport, the national park and the city centre, a budget-friendly option if you're travelling light.
Top tips for finding cheap flights to Foz do Iguaçu
- Book your long-haul leg to São Paulo or Rio de Janeiro three to six months ahead, then add the domestic connection separately if it works out cheaper - the price charts above show how fares typically move.
- Flying midweek, particularly Tuesday or Wednesday, is usually cheaper than weekend departures on both the international and domestic legs.
- Stay flexible with your dates where possible - shifting a trip by even a few days around school holidays can make a noticeable difference to fares.
- Compare airlines and routings rather than booking the first option - a European hub connection can sometimes beat a direct British Airways service, especially outside peak season.
Travel essentials
UK passport holders can currently enter Brazil for tourism without a visa for stays of up to 90 days, though it's always worth checking the latest entry requirements before you fly. The currency is the Brazilian real (BRL); cards are widely accepted in Foz do Iguaçu, though it's useful to carry some cash for local buses and smaller vendors. No specific vaccinations are mandatory for entry from the UK, but travellers heading further into the Amazon region sometimes need a yellow fever certificate, so check with your GP or a travel clinic if your trip extends beyond Foz do Iguaçu. As the city sits right on Brazil's border with Argentina and Paraguay, keep your passport handy if you're planning to cross for the Argentine side of the falls.
