Iguazú Falls is a massive chain of over 275 waterfalls stretching nearly 2 miles across the border between Argentina and Brazil. Some drops reach around 260 feet (80 meters), with constant mist rising from the crashing water. Walkways take you surprisingly close, and nearby trails wind through rainforest where you might see toucans, monkeys, or coatis.
This guide focuses on the Argentine side. Whether you're visiting on your own or booking something more structured, it’ll help you figure out the best way to experience the falls without unnecessary stress.
The falls sit where Argentina’s Misiones Province meets Brazil’s Paraná state, just outside Puerto Iguazú on the Argentine side—about 11 miles (18 km) from town. Across the river, Foz do Iguaçu is the main base on the Brazilian side, about 17 miles (27 km) away. Paraguay’s not far either, so this corner of South America brings together three countries.
The falls are inside protected national parks on both sides, which has helped keep the area relatively untouched. It still feels wild, with thick jungle, birdsong, and surprisingly little development near the water itself.
Argentina’s side gives you more ways to experience the falls and gets you closer to the falls. About 80% of them are here, and a network of walkways makes it easy to explore at different levels. Some trails lead you right up to the base of the falls; others take you above them for a wider view.
There are a few main circuits: the Upper Circuit gives you wide views from above, while the Lower Circuit brings you closer to the water. The most dramatic section, Devil’s Throat, is reached via a long walkway across the river—worth it for the view straight into the plunge. And if you’re interested in seeing the local wildlife, this side has more walking trails, so you have more chances of seeing birds, monkeys, or butterflies along the way.
If you're planning to spend a full day at the falls, this side gives you more to do and more ways to experience it.
Knowing how to visit Iguazu Falls starts with understanding your transportation options, which are easier than you might think. It’s worth noting that the surrounding region isn’t especially well-connected by rail. Nearly all travel here happens by road or air.
Flying is the easiest way to get to Iguazú Falls from Buenos Aires. You’ll find regular flights from both Aeroparque and Ezeiza to Puerto Iguazú (IGR), and it takes about 1 hour and 45 minutes. After landing, it’s around a 20-minute drive to town or about 30 minutes if you’re heading straight to the park.
If you're already in the north, getting to the falls by road works well. From Posadas, it’s about a 4-hour drive on Route 12, with jungle views and mate plantations along the way.
The drive through Misiones Province is interesting, and you can make stops at places like the San Ignacio ruins. Just watch out for patchy road conditions and avoid driving at night outside major towns.
Coming from Brazil is pretty straightforward. From Foz do Iguaçu, you can catch a local bus to the Argentine side. You’ll go through immigration at the border, then continue on to either Puerto Iguazú or the park itself. The whole thing usually takes between 1 and 2 hours.
If you're coming from Paraguay, the route involves crossing into Brazil first—usually from Ciudad del Este over the Friendship Bridge—then crossing again into Argentina. It's two borders, but manageable in half a day. There are also a few river crossings straight into Puerto Iguazú, depending on where you’re starting from.
You can visit any time of year, but each season has its pros and cons. The wet season (December to February) brings the highest water levels, but it also gets hot and humid, and some trails may close if the river rises too much.
Spring (September–November) and fall (March–May) are usually a good time to go—decent water flow, mild weather, and fewer crowds. It’s easier to walk the trails comfortably, and the views are still impressive.
In winter (June–August), there’s less water, but you’ll get clearer views and cooler temperatures—around 65–75°F (18–24°C). It’s a quieter time to visit, and better if you prefer to hike without the heat or mist. If you can, try to avoid holiday periods like Easter or Christmas, when things get much busier with local visitors.
The park on the Argentine side is open daily from 8:00 AM to 6:00 PM, with the last entry at 4:30 PM. As of 2025, tickets for foreign visitors cost ARS 35,000 (about USD $35–40, depending on the exchange rate). That gets you into all the walking circuits, the Devil’s Throat walkway, and the Ecological Train. You can pay with card or cash—just make sure it’s in pesos.
If you’re planning to return the next day, get your ticket stamped before leaving—your second day will be half price. Kids under 6 get in free, and discounts are available for students and seniors with valid ID. During peak season, it’s worth booking online to save time at the gate. Tickets are only good for one day, so aim to arrive early if you want to see everything.
You’ll want to pack for heat, humidity, and the chance of getting soaked. A small waterproof backpack is helpful for keeping your stuff dry. Quick-dry clothes and sturdy shoes with decent grip go a long way, especially on misty trails like the Lower Circuit.
Sunglasses, a wide-brimmed hat, and water-resistant sunscreen are a must—sun exposure can be intense. Mosquitoes are around, especially in the warmer months, so bring repellent with DEET.
The park is fairly easy to get around, even if you have mobility needs. Most of the main walkways are flat or gently sloped, and the train is wheelchair accessible. The path to Devil’s Throat was designed without stairs, so it’s manageable for most visitors.
Facilities are spaced out well. You’ll find bathrooms at the major stops, places to eat (from snack stands to sit-down restaurants), and a few shops near the entrance and main stations. There are lockers you can use near the gate and first aid points around the park if needed. Some areas have free Wi-Fi, though it doesn’t work everywhere.
There are plenty of things to do here, beyond watching the falls from a distance.
Devil's Throat is the largest and most powerful section of Iguazu Falls. Water crashes 260 feet (80 meters) into a narrow gorge, creating clouds of mist and a constant low rumble you can feel as much as hear. To get there, take the Ecological Train to the final stop, then follow a 0.6-mile (1-kilometer) walkway over the upper river.
As you get closer, the sound builds, and then you’re suddenly standing right at the edge of the drop. Go early or late in the day for fewer crowds.
Both circuits are worth doing, and they’re pretty different. The Upper Circuit stays level and runs above the falls, with wide views across the cascades and river. It’s about 1.1 miles (1,750 meters), doesn’t have stairs, and doesn’t take too long.
The Lower Circuit is a bit more of a hike—around 1 mile (1,700 meters)—with steps and jungle paths that bring you much closer to the water. You’ll feel the spray and see smaller falls up close, like Salto Bossetti. It’s also where you’ll likely notice more wildlife, especially in the quieter stretches. Do both if you have the time.
This train runs through the park and makes it easier to get between the main areas without walking too much. It’s gas-powered and open-air, so you can enjoy the forest as you ride.
There are three stops: one at the entrance, one near the circuits, and one at Devil’s Throat. Trains come every 30 minutes and are included in your entry ticket. It’s especially helpful if you're trying to save energy or traveling with kids. Some people walk the Green Trail in one direction and take the train back.
If you’re up for getting soaked, the Gran Aventura boat trip is a good way to experience the falls from below. You start with a ride through the jungle in an open truck, then board a speedboat that takes you up the river and directly under some of the cascades.
It’s loud, wet, and fun—but don’t bring anything you don’t want drenched. The whole thing takes 1–2 hours.
The park’s forest is full of animals, so you’ll probably see a lot without even trying. Coatis are the most visible—they wander the walkways looking for food and aren’t shy. Just don’t feed them.
Toucans show up here and there, usually in the quieter areas. You might also see monkeys, especially in the early morning, plus lizards and the occasional caiman near water.
Butterflies are everywhere, including the big blue morphos that glide through sunny paths.
Give yourself at least two full days to really take in Iguazú Falls. An ideal itinerary would start with the Argentine side—plan to hit Devil’s Throat early, before it gets crowded. Then walk the Upper Circuit for wide views and the Lower Circuit for closer ones.
Use your second day to either see the Brazilian side for a broader view or revisit a trail on the Argentine side when the light is different. If you’ve got the energy, the boat ride under the falls is a fun way to change things up. You’ll also have more time to take breaks, watch for wildlife, or just enjoy the area without feeling pressed for time.
It’s worth arriving the day before your park visit and leaving the day after. That way, you're not squeezed by travel and can stay flexible if the weather turns.
When deciding how to visit Iguazu Falls, a guided trip makes sense if you’re short on time, don’t speak Spanish, or just want someone else to handle the details. Guides usually know how to avoid crowds, explain what you’re seeing, and point out wildlife or viewpoints you’d probably miss otherwise.
Full-service packages are also a good fit if it’s a special trip—like a honeymoon—or if you’d rather not think about logistics. Our tailor made trips are created by local travel experts who know the falls inside and out. They can work together with you to create your ideal itinerary, and are available during your trip 24/7.
Most people base themselves in Puerto Iguazú, about 20 minutes from the park. It’s an easy place to get around, with a range of places to stay—hostels, guesthouses, hotels—and plenty of restaurants and tour operators. It’s also cheaper than staying inside the park and makes a good base if you’re visiting both the Argentine and Brazilian sides.
If you’re after more comfort and don’t mind paying more, the Gran Meliá Iguazú is inside the park itself. It’s the only hotel with that kind of access. You can walk to the trails early in the morning or stay after everyone else has left. Some rooms even look out over the falls.
You could also stay in Foz do Iguaçu on the Brazilian side. It’s convenient if you're planning to cross the border anyway, and it gives you a wider range of places to stay. Just make sure to book ahead during peak months like December through February or in July—places fill up fast.
You can, but it’s tight. If you’ve only got one day, stick to the Argentine side and make the most of it. Get there right when the park opens (8:00 AM) and start with the Devil’s Throat walkway before the crowds roll in. After that, do the Upper and Lower Circuits. It’s a lot to squeeze in, so you’ll need to keep a steady pace.
You probably won’t manage both the boat ride and all three circuits in one day—pick what matters most to you. To save time, book your tickets online and take a taxi straight to the park instead of waiting for the bus. Two days is better if you can swing it, but if not, it’s still worth going.
