The towns on either side of the falls
Best Things to Do in Foz do Iguaçu and Puerto Iguazú
The falls are the reason you came, but the twin towns either side of them — Brazilian Foz do Iguaçu and Argentine Puerto Iguazú — hold enough to fill the days around your park visits. Here's what's worth your time.
Check dates and availability ↗Two towns, one destination
The Iguazú falls are flanked by two very different towns, one in each country, and knowing what each offers helps you decide where to base yourself and how to fill the hours you're not on the catwalks. Foz do Iguaçu, on the Brazilian side, is the larger and busier of the two, with a wider spread of hotels, restaurants and attractions beyond the falls themselves. Puerto Iguazú, across the river in Argentina, is smaller, quieter and more relaxed, an easy town to wander in the evening. Both sit close to the point where Brazil, Argentina and Paraguay meet, and many visitors end up spending time in both — so it's worth treating the whole area, rather than one town, as your destination.
The Itaipu Dam
Just outside Foz do Iguaçu sits one of the largest hydroelectric dams in the world, straddling the border between Brazil and Paraguay, and it's a genuinely impressive half-day out. Guided visits run through the scale of the thing — the sheer wall of concrete, the spillways, the engineering behind a project that supplies a huge share of the region's electricity — and there are usually different tour formats depending on how deep you want to go. It's a striking counterpoint to the wild power of the falls: the same river energy, harnessed. If the weather turns or you've had your fill of catwalks, this is one of the area's most reliable alternatives, and it photographs far better than a dam has any right to.
The Bird Park (Parque das Aves)
Near the entrance to the Brazilian national park, a well-regarded bird park lets you walk through large aviaries where toucans, macaws, parrots and other rainforest species live at close range — many of them rescued birds. It's an easy, family-friendly couple of hours, and because it sits right by the park gate it slots neatly onto the front or back of a Brazilian-side falls day. Being that close to a scarlet macaw or an outsized toucan is the kind of thing that lands especially well with kids, and it puts names and faces to the birdlife you'll have glimpsed darting through the spray at the falls. Book it around your park visit and you barely lose any time.
The Three Frontiers landmark
One quietly memorable stop is the point where three countries meet: from a marked lookout on the Brazilian side you can see the confluence of two rivers and, across the water, both Paraguay and Argentina at once, each with its own matching monument. It's not a long visit — it's a viewpoint and a photo of standing at the meeting of three nations — but it's a nice way to grasp the geography that makes this corner of South America so distinctive. There's an equivalent vantage on the Argentine side near Puerto Iguazú. Either version works best at a relaxed pace, ideally toward the end of the day when the light is soft over the rivers.
Slower pleasures in Puerto Iguazú
The Argentine town rewards a gentler kind of visit. Puerto Iguazú is small enough to explore on foot, with a laid-back main strip of restaurants and a chance to eat your way through Argentine classics — the beef and the wine live up to their reputation — after a long day on the trails. There are riverside viewpoints, low-key markets and easy access to a couple of small nature and wildlife spots on the town's edges. It's less about ticking off big attractions and more about winding down, which makes it a pleasant place to sleep if you want the falls without a lot of urban bustle. Many visitors find the contrast between busy Foz and calm Puerto Iguazú one of the trip's small pleasures.
Adventure add-ons at the falls
Beyond the sights in the towns, the parks themselves offer bookable adventures that are worth building into your days. The speedboat safari on the Argentine side is the standout — a fast run along the lower river that takes you straight into the drenching spray beneath the cataracts, and the thing most people rank as their favourite moment. Helicopter flights over the gorge, available near the Brazilian park, give you the aerial perspective the catwalks can't, and guided rainforest walks add wildlife and context at ground level. These fill the space between the two main park days nicely, especially if you've given yourself three or four nights in the area rather than a quick in-and-out.
Where the towns fit your trip
Pulling it together: base yourself in Foz do Iguaçu if you want more choice of hotels and easy access to the dam, the bird park and the Brazilian falls, or in Puerto Iguazú if you'd rather a smaller, calmer town and you're prioritising the Argentine side. Plenty of people sample both. However you split it, two or three nights in the area gives you room for the falls plus a couple of these extras without cramming. And when you're ready to move on, the towns are your springboard to the wider trip — a two-hour flight to Rio de Janeiro, or a short hop across to Buenos Aires — so plan the falls days knowing what comes next.
