4 Days at Iguazu Falls: Devil's Throat, Boat Rides & Both Sides of the Border
Nearly 275 cascades on the Argentina-Brazil border: walkways beside the water, a boat beneath it and the panorama from both national parks, in four days.
Nearly 275 cascades on the Argentina-Brazil border: walkways beside the water, a boat beneath it and the panorama from both national parks, in four days.
Most visitors base on the Argentine side in Puerto Iguazú, a small jungle town a short drive from both the national park and the border, with a wider range of budget lodging than its Brazilian counterpart.
✈️ Fly into Iguazú International (IGR) 💵 ~$15-20 taxi from the airport 🕐 Plan around your flight's landing timeThis looping walkway drops down toward river level and passes directly beneath several individual falls, including Salto Bossetti and Dos Hermanas, the most intimate perspective the Argentine side offers and a gentle introduction before the longer Devil's Throat walk tomorrow. Coatis, small raccoon-like mammals, are everywhere along this trail and thoroughly used to people, admire them but don't feed or approach them.
🚶 Enter through the Argentine park's Central Station 💵 Park ticket ~$34 (foreign adult, 2026 rate) 🕐 Early afternoon, allow 1.5 to 2 hrsAvenida Córdoba is the main strip for parrilla-style grilled meats and river fish like surubí, a relaxed first night before two longer park days ahead.
🚶 A short walk or taxi from most hotels 💵 ~$15-25 dinner with a drink 🕐 Argentine dinners run late, 8:30 PM onwardA small train carries you to Estación Garganta del Diablo, then a flat 1.1km metal walkway crosses the river straight to the edge of the Devil's Throat, a U-shaped chasm where roughly half the river's flow drops nearly 80 meters into a permanent cloud of spray. It's the single most dramatic view at either park, go early before the train queue and the crowds build.
🚂 Free Eco-Train, runs every ~20 min 💵 Included in park entry 🕐 Arrive by park opening, ~8 AMWhere the Lower Circuit goes underneath the falls, this walkway runs flat along the clifftop right at the lip of a dozen different cascades, looking straight down the drop rather than up at it, a completely different vantage on the same falls you saw from below yesterday.
🚶 Starts near Central Station 💵 Included in park entry 🕐 Late morning, allow ~1.5 hrsA jeep transfer through the jungle drops you at the river for this speedboat trip, which finishes by driving straight into the spray at the base of San Martín and Tres Mosqueteros falls, everyone gets completely soaked and it's genuinely one of the trip's highlights. Bring a dry bag for phones and cameras, or leave them at the boat dock lockers.
🚤 ~12 min in the falls' spray 💵 ~$70-85 per person, book same-day at Central Station 🕐 Afternoon departures run continuouslyThe Tancredo Neves International Bridge is the only road crossing, about 15km from Puerto Iguazú. Shared buses stop at both immigration posts, everyone gets off to have passports stamped exiting Argentina and entering Brazil, then reboards, budget a full hour for the crossing and don't lose your ticket. A valid passport is required for every nationality; depending on your passport, Brazil may also require an advance eVisa, so check requirements before you fly, not at the border.
🚌 Shared bus, ~40 min plus immigration stops 💵 ~$4-5 one-way bus fare 🕐 Depart by 8:30 AM to beat the queueBrazil's park covers a fraction of the trail distance of Argentina's, but its single walkway is purpose-built for the wide shot, facing the full curtain of falls head-on from across the canyon, ending at a platform and elevator right beside the Devil's Throat's outer face. Where Argentina puts you inside the falls, this is the view that makes sense of the whole horseshoe at once.
🚶 Shuttle bus from the park entrance to the trailhead 💵 Brazilian park ticket ~$28 🕐 Late morning into early afternoon, allow ~2 hrsRight next to the Brazilian park's entrance, this walk-through aviary houses toucans, macaws and other Atlantic Forest species in large enclosures you walk directly into, a good complement to whatever wildlife you've spotted on the trails and an easy stop before heading back into Foz do Iguaçu for the night.
🚶 Adjacent to the Brazilian park entrance 💵 ~$25 entry 🕐 Mid to late afternoon, allow ~1.5 hrsThese ring-tailed relatives of the raccoon are the park's unofficial mascots, bold, constantly foraging, and completely unbothered by people, especially around the picnic and snack areas. They look harmless but they bite, and human food genuinely harms them, so admire from a couple of meters back and never hand-feed one, no matter how close it wanders.
🐾 Most common near Central Station and the picnic areas 💵 No extra cost 🕐 Any time, most active in the morningBack in Puerto Iguazú, this riverside obelisk marks the exact point where Argentina, Brazil and Paraguay meet, with each country's matching landmark visible across the water, a quick, easy stop and a good last look at how much geography this trip has actually covered.
🚶 Short walk from central Puerto Iguazú 💵 Free 🕐 Late morning, before checkoutIguazú International (IGR), a short drive from Puerto Iguazú, has the widest range of domestic connections; Foz do Iguaçu's airport (IGU) on the Brazilian side is the better choice if your onward flight routes through Brazil. Either way, decide before crossing back so you're not stuck re-crossing the border with a tight connection.
🚗 ~20 min to either airport 💵 ~$15-20 taxi 🕐 Leave at least 2.5 hrs before an international flightIf you re-enter the Argentine park on consecutive days, a discounted second-day ticket is available at the gate, worth asking about if you want extra time on either circuit.
The shared Crucero del Norte / Rio Uruguay bus between Puerto Iguazú and Foz do Iguaçu runs hourly for a few dollars, a fraction of what private transfers charge for the same route.
Lodging and meals both run noticeably cheaper on the Argentine side, and the border crossing is easy enough to do as a single day trip rather than switching hotels.
The queue for the first morning train can run 30-45 minutes; the walking trail alongside the tracks to Cataratas Station is scenic, uncrowded, and gets you moving immediately.
On nights around the full moon, the park opens for guided evening walks out to the Devil's Throat, an entirely different, near-empty experience of the same view, book well ahead as slots are limited.
The bird enclosures are far more active in the cooler first hour after opening, before the afternoon heat sends most birds into the shade.
