Iguazu Falls (Puerto Iguazu)
The falls you walk into rather than look at - two days of catwalks, spray and jungle, with the Devil's Throat saved for last.
Iguazu Falls is 275 cataracts strung across nearly three kilometres of river, and the Argentine side is the one you walk into: steel catwalks running above, below and right to the lip of the Garganta del Diablo, where half the river drops into a permanent cloud of spray. Parque Nacional Iguazu wraps the whole thing in Atlantic rainforest full of coatis, toucans and butterflies, and takes two full days to do properly. Puerto Iguazu, the small humid border town twenty minutes down the road, is where you sleep.

Why you'll love Iguazu Falls (Puerto Iguazu)
The Devil's Throat a long walkway carries you out over the flat brown river to the exact point where it falls away into thunder and spray
Two days, not one the upper, lower and island circuits each reach different falls, and morning and afternoon light change all of them
The jungle coatis on the path, toucans overhead and blue morpho butterflies on the railings, inside a working rainforest reserve
Getting soaked boardwalks and boats put you close enough that a poncho is standard kit rather than a souvenir

When to avoid Iguazu Falls (Puerto Iguazu)
No genuinely bad season, but two things move: heat and water. December to February is hot, humid and busy with Argentine holidaymakers, and heavy summer rain can shut the Devil's Throat walkway or the boat runs for a day. Winter is far more comfortable, and lower water means clearer views rather than less spectacle.
Top things to do in Iguazu Falls (Puerto Iguazu)
-
Garganta del Diablo - the walkway to the lip
scenic 👍 PopularA long catwalk crosses the flat brown river to a platform at the point where it disappears: half the Iguazu's flow into one horseshoe eighty metres deep, spray coming back up past you and swifts flying through it. Go early or late, because the middle of the day is a queue.
-
Circuito Inferior - the lower circuit, under the falls
scenic 👍 PopularStairs and boardwalks drop through the forest to the foot of the cliffs, with viewpoints looking up at Salto Bossetti and Dos Hermanas and the landing where the boats leave. This is where you get wet, and where the falls stop being scenery and start being weather.
-
Circuito Superior - the upper circuit, along the crest
scenic 👍 PopularAn easy, mostly flat loop along the top edge of the smaller falls, so the water leaves from directly beneath your feet and lands somewhere out of sight. Best in morning light, and the most manageable circuit for young children and anyone avoiding stairs.
-
Gran Aventura - the boat run into the spray
adventure ⭐ Highly recommendedInflatables power up the canyon and drive deliberately into the curtain below Salto San Martin until nobody can see anything at all. You will be soaked to the skin, so use the dry bags handed out at the landing and leave everything else behind.
-
Sendero Macuco - the jungle trail to Salto Arrechea
nature wildlife hiking ⭐ Highly recommendedA quiet forest track of a few kilometres each way, away from the walkways entirely: capuchin monkeys, birdsong and a steep final descent to a small fall and pool. Start at opening, while animals are still moving and before the heat arrives.
-
Tren Ecologico de la Selva - the jungle train
scenicA narrow-gauge open train links the entrance, the circuits and the Devil's Throat station through the forest. Queues at peak times run long, so many people walk the short Sendero Verde to the first stop and ride only the leg that matters.
-
Isla San Martin - the island in the middle of the falls
scenicA launch crosses from the lower circuit to the island facing Salto San Martin, where a steep staircase climbs to viewpoints no walkway reaches and a small beach. Access is suspended whenever the river runs high, which is often, so treat it as a bonus.
-
Paseo de Luna Llena - the full-moon walk to the Devil's Throat
scenicOn the nights around each full moon the park reopens after dark for a guided walk out to the Garganta, where the spray throws a colourless lunar rainbow. Numbers are capped and it books out well ahead; cloud or high water can cancel it.
-
Hito Tres Fronteras - where three countries meet
scenicAn obelisk in Argentine blue and white looks down on the muddy junction of the Iguazu and the Parana, with Brazil and Paraguay marking their own banks opposite. Craft stalls and a promenade above the confluence; go for sunset and the view rather than the monument.
-
Guira Oga - rescued birds of the Atlantic forest
nature wildlifeA rescue and breeding centre on the road to the park, holding toucans, owls and harpy eagles that arrived injured or confiscated. Guided walks explain how little of the Atlantic forest is left, and it is the surest way to actually see the birds up close.
-
River fish and Misiones mate - eat what the province grows
foodSurubi and pacu off the Parana turn up grilled or folded into empanadas, alongside Paraguayan-influenced chipa and sopa paraguaya. Yerba mate grows in the red earth all around Puerto Iguazu, and Misiones supplies most of what the country drinks.

A little history of Iguazu Falls (Puerto Iguazu)
The Guarani knew the falls long before Europeans did, and their story explains them: the serpent god M'Boi, cheated of the girl Naipi, split the river in his rage and left her falling forever. Alvar Nunez Cabeza de Vaca came through in 1542, the first European to record the cataracts, and called them the Saltos de Santa Maria; the Guarani name outlasted his. For three centuries afterwards the falls sat behind a wall of forest on the far edge of Jesuit mission country, whose ruins still stand down the road, and almost nobody saw them.
Access came late. In 1901 Victoria Aguirre, a Buenos Aires traveller who had come upriver to see them, paid for a track to be cut from the landing to the falls; the settlement that grew at that landing became Puerto Iguazu, and its main avenue still carries her name. Argentina made the surrounding rainforest a national park in 1934, among its first, and UNESCO listed it fifty years later. The catwalks have been carried away by floods and rebuilt more than once, which tells you most of what you need to know about the river.
Guarani communities live along the river and give the falls their name, Y-guazu, big water

FAQs about Iguazu Falls (Puerto Iguazu)
▸ When is the best time to visit Iguazu Falls?
August is the pick: winter here is warm rather than hot, the humidity drops and the walkways are bearable at midday. Water is lower then, which means clearer views and more reliable boat runs rather than a lesser spectacle. Summer brings the heaviest flow along with heat, humidity and Argentine holiday crowds. Rain falls in every month, so pack a poncho whenever you come.
▸ Should I see the Argentine or the Brazilian side?
Both, if you can, because they are different experiences. The Argentine side holds most of the falls and is the immersive one, a day or two of catwalks that put you above, below and at the lip of the Devil's Throat. The Brazilian bank is the panorama, and takes a couple of hours. With time for only one, make it this side.
▸ How many days do you need at Iguazu Falls?
Two days in the Argentine park is the honest answer: the upper and lower circuits on one, the Devil's Throat plus a boat run or the Macuco trail on the other. Get your ticket stamped before leaving and a second consecutive day is heavily discounted. Add half a day for the Brazilian viewpoints and three nights covers it.
▸ What should I take into the park?
A rain poncho, a dry bag or waterproof case for your phone, shoes you do not mind soaking, sun cover, water and insect repellent. Do not feed the coatis: they are bold, they bite, and they will open an unattended bag. Distances add up, so expect to walk ten kilometres or more across a full day.
▸ Is Iguazu expensive?
Park entry is the biggest single cost of the day, and foreign visitors pay a higher band than Argentine residents. Staying inside the park or at the jungle resorts is expensive; Puerto Iguazu town is not, and eating there is good value. Boat rides and organised tours are the optional extras that add up fastest.
