Brazil
Iguazu Falls (Foz do Iguacu)
The whole three-kilometre sweep of the world's greatest waterfall seen head-on, and a catwalk that walks you into the spray of the Devil's Throat.
Iguazu Falls is a chain of 275 cascades strung along nearly three kilometres of the Iguacu River, and the Brazilian bank is the side that faces them. One cliff-edge trail runs the length of the panorama and finishes on a catwalk pushed out into the river at the foot of the Devil's Throat, close enough to soak you through. Behind it sits Foz do Iguacu, a humid border city of Lebanese, Chinese and Paraguayan communities, with the Itaipu dam on its northern edge and two other countries a bridge away.

Why you'll love Iguazu Falls (Foz do Iguacu)
The panorama Brazil owns the facing bank, so you see the full arc of falls at once instead of one cascade at a time
The catwalk the trail ends on a walkway out over the river below the Devil's Throat, in permanent roaring spray
Rainforest subtropical jungle either side of the path, with coatis, capuchins and toucans working the trail all day
Three countries the Iguacu meets the Parana just downstream, and Argentina and Paraguay are each one bridge away

When to avoid Iguazu Falls (Foz do Iguacu)
No bad season - the falls run all year. December to February is hot, humid and busiest with Brazilian school holidays, and heavy rain can push the river into flood, which shuts the boat rides and sometimes the catwalks for days. A long dry spell does the opposite and thins the flow. Weekends fill the walkway whatever the month.
Top things to do in Iguazu Falls (Foz do Iguacu)
-
Trilha das Cataratas - the cliff walkway to the Devil's Throat
scenic nature wildlife 👍 PopularThe Brazilian park is essentially one trail: a little over a kilometre along the canyon rim with the falls opening up opposite, ending on a catwalk that runs out over the water beneath the Devil's Throat. Bring a poncho or accept being drenched, and keep your phone in a dry bag.
-
Macuco Safari - the boat ride under the falls
adventure ⭐ Highly recommendedA jungle truck down through the forest, then an inflatable up the rapids and straight in under the Tres Mosqueteiros cascade, twice, because once is never enough for the driver. You come out wrung out. It is the single most memorable thing on this side of the river.
-
Parque das Aves - walk-in aviaries opposite the park gate
nature wildlife 👍 PopularA serious rescue and breeding centre rather than a roadside zoo, with walk-through aviaries where toucans and macaws land beside you, plus harpy eagles and a butterfly house. Half the residents are confiscated trafficking birds. Easy to combine with the falls in the same day.
-
Itaipu Dam - the wall across the Parana
culture arts 👍 PopularBrazil and Paraguay's shared hydroelectric plant is nearly eight kilometres of concrete and one of the largest power stations on earth. The panoramic tour runs the crest; the technical circuit takes you inside to the turbine hall. Floodlit after dark on set evenings.
-
Full-moon walk at the falls - the trail after dark
scenic ⭐ Highly recommendedFor a handful of nights around each full moon the park reopens at night and walks small groups down the lit trail to the Devil's Throat, where the spray sometimes throws a colourless moonbow. Books out well ahead and is cancelled if cloud beats the moon.
-
Helicopter flight over the falls - the view Argentina bans
scenic adventureOverflights are legal only from the Brazilian side, so this is the one place you can see the horseshoe from directly above and take in how far the gorge runs downstream. Short, loud and pricey, and worth it if the aerial shot is the thing you came for.
-
Poco Preto and Bananeiras trails - the park's quiet side
nature wildlife adventureGuided routes away from the main walkway, through Atlantic rainforest to the riverbank by foot, bike or electric cart, with rafting and a wildlife float on the calm upper river. This is where you actually hear birds instead of water.
-
Marco das Tres Fronteiras - where three countries meet
scenicAn obelisk in Brazilian colours on the bluff where the Iguacu empties into the Parana, looking across at matching markers in Argentina and Paraguay. Best at sunset, when the site turns into a small park with food stalls and a nightly show.
-
Templo Budista Chen Tien - hilltop statues above the city
culture artsA Chinese Buddhist temple on a rise near the Paraguayan bridge, surrounded by well over a hundred stone figures and a large gilded Buddha. Quiet, free to wander and a reminder that this border town's population came from everywhere.
-
Eat across three borders - churrasco, Lebanese and Paraguayan
foodFoz eats better than a park town should. All-you-can-eat churrascarias do the rodizio of grilled meat, decades-old Lebanese places do kibbeh and esfiha for the Arab community, and street counters sell Paraguayan chipa, the cheese bread sold hot from a basket.

Coach
Terminal Rodoviario Internacional
Overnight coaches run in from Curitiba, Sao Paulo and Florianopolis, and cross-border services connect Puerto Iguazu and Ciudad del Este
Drive

Day trips from Iguazu Falls (Foz do Iguacu)
Argentine side of the falls
Full dayThe other bank
The complementary half of the same waterfall: upper and lower circuits of steel catwalks that put you among and above the cascades, a jungle train, and a long walkway out to the lip of the Devil's Throat. Slower and sweatier than Brazil, and a full day rather than a morning.

A little history of Iguazu Falls (Foz do Iguacu)
The Guarani lived along this stretch of river long before Europeans reached it, and the name is theirs: y guasu, big water. Their story gives the gorge to a serpent god who split the river in rage when a girl fled him by canoe. The first European to record the falls was the Spaniard Alvar Nunez Cabeza de Vaca in 1542, who called them Santa Maria and had his boats carried around them. For three centuries afterwards this was contested backcountry between Spanish and Portuguese claims, and the modern borders only settled after the Paraguayan War.
Brazil planted a military colony at the river junction in 1889, and it grew into Foz do Iguacu. The national park came in 1939, a few years after Argentina's, and UNESCO listed it in 1986. What changed the town, though, was concrete and trade: the Friendship Bridge to Paraguay in 1965, then the building of Itaipu through the 1970s, which drew tens of thousands of workers, drowned the Guaira falls upstream and left a city that now lives on power, smuggling, shopping and waterfalls in roughly equal measure.

FAQs about Iguazu Falls (Foz do Iguacu)
▸ Which side of Iguazu Falls is better, Brazil or Argentina?
They do different jobs. Brazil gives you the wide view of the whole system and takes half a day. Argentina puts you on catwalks among and above the water and takes a full one. If you have two days, do both; if you have one and want the postcard, stay in Brazil.
▸ When is the best time to visit the Brazilian side?
August is the pick: dry, mild and comfortable for a long day outdoors. The falls flow year-round, though, so any month works. Summer brings the heaviest water along with heat, humidity and the biggest crowds.
▸ How many days do you need in Foz do Iguacu?
Two full days covers the Brazilian park in a morning, the Argentine side the next day, and the bird park in the gaps. A third lets you add Itaipu, the frontier marker and one of the quieter forest trails without rushing.
▸ Do you need a passport to visit the Argentine side?
Yes, and for Paraguay too. Both are ordinary international crossings with immigration posts on the bridges, so carry your passport and check your own nationality's entry rules for Argentina before you go. Organised tours handle the stops but you still queue.
▸ Will I get wet at the falls?
On the Brazilian side, yes. The final catwalk sits in constant spray from the Devil's Throat and there is no dry route past it. Ponchos are sold at the park, a dry bag or waterproof case protects a phone, and quick-drying clothes beat jeans.
▸ Is Foz do Iguacu safe?
The national park and the hotel strip are straightforward. In town, use normal city sense: keep valuables out of sight, take taxis after dark rather than walking the emptied centre, and be alert in the crowds and queues around the Paraguayan border crossing.
