You've probably seen the photos. Those massive, thundering walls of water that look like the Earth just decided to open up and swallow the river whole. But honestly, when you look for the location of Iguazu Falls on map, it’s a bit more complicated than just pointing at a single dot in South America. It’s not just a waterfall; it’s a sprawling liquid border.
It sits right on the edge of two giants: Argentina and Brazil.
Most people think you can just "show up" at the falls, but because of how they sit on the map, your experience changes completely depending on which country’s dirt you're standing on. You aren't just visiting a park; you’re navigating an international boundary.
The Literal Crossroads: Finding Iguazu on the Map
If you’re looking at a world map, zoom in on that little "beak" of Argentina that pokes up between Brazil and Paraguay. That’s the Misiones Province. The falls are located at the confluence of the Iguazu River and the Paraná River.
Specifically, the coordinates are roughly 25.6953° S, 54.4367° W.
But here’s the kicker. The falls aren't just a straight line. The river makes a big, lazy U-turn—kinda like a reversed letter "J"—and that shape is what creates the 275 individual drops. On a map, about 80% of the actual waterfall "curtain" is physically located in Argentina. However, because the river canyon opens up toward the other side, the most famous panoramic views are actually in Brazil.

The Triple Frontier
Just a few miles downstream from the falls is a spot called the Hito Tres Fronteras. You can stand on a riverbank in Puerto Iguazú (Argentina) and look across the water to see Foz do Iguaçu (Brazil) to your right and Ciudad del Este (Paraguay) to your left.
It’s one of the few places on Earth where three countries meet at a natural river junction.
While Paraguay doesn't actually "own" any part of the falls, it’s a huge part of the local map and economy. Many travelers stay in Brazil or Argentina but pop over to Paraguay for tax-free shopping. Just keep your passport handy; the border guards here don't play.
Which Side Are You Actually On?
Understanding the location of Iguazu Falls on map helps you plan your days. If you're a "hiker," you want Argentina. If you're a "photographer," you want Brazil.
The Argentine Side (The Stage)
In the Iguazú National Park (Argentina), you are literally walking on the falls. The map here is a web of steel walkways. One minute you’re in the middle of a subtropical rainforest dodging coatis (think long-nosed raccoons), and the next, you’re standing on a platform hanging over the "Devil’s Throat."

It’s intense.
You’ll take a kitschy little green train to get to the main trails. Don't skip the Lower Circuit; it gets you right into the spray.
The Brazilian Side (The Front Row Seat)
Over in the Parque Nacional do Iguaçu (Brazil), the map is much simpler. There’s basically one main trail. It runs along the canyon wall. Because most of the water is falling away from Brazil, you get that classic, wide-angle "National Geographic" shot.
You see the scale of it here.
Honestly, the Brazilian side is a lot faster to visit. You can do the whole thing in three hours. Argentina, on the other hand? You need a full day. Minimum.

How to Get There Without Getting Lost
Unless you’re doing a massive South American road trip, you’re flying in. The geography of the region is served by two main airports, and picking the wrong one can be a headache.
- Cataratas del Iguazú International Airport (IGR): This is the one in Argentina. It’s about 15 minutes from the park entrance. If you’re coming from Buenos Aires, fly here.
- Foz do Iguaçu/Cataratas International Airport (IGU): This is the Brazilian side. It’s super close to the park entrance and the famous Bird Park (Parque das Aves). If you’re coming from São Paulo or Rio, this is your spot.
A pro tip: You cannot easily fly between these two airports. Even though they are only about 15 miles apart as the crow flies, there are no direct flights. You’d have to fly all the way back to a hub and return. To cross the border, you take a taxi, a bus, or a private transfer.
Realities of the Map: The Weather and the Water
The falls are in a tropical rainforest. It’s humid. Like, "my shirt is stuck to my back five minutes after leaving the hotel" humid.
The flow of the river is also wildly unpredictable.
In late 2023, for example, massive floods actually washed away parts of the walkway to the Devil’s Throat. When you look at the location of Iguazu Falls on map, remember that the river is alive. During the dry season, the "275 waterfalls" might look more like 150. During the rainy season, it becomes one giant, brown, terrifying wall of energy.
Where to Stay?
- Puerto Iguazú (Argentina): Kinda laid back, more "jungle" vibes, and generally cheaper.
- Foz do Iguaçu (Brazil): A big city. More high-rise hotels, better nightlife, and a bit more organized.
Actionable Next Steps
If you're planning to pin this location on your own map, here’s what you actually need to do:
- Check your visa requirements. As of 2025/2026, rules for Americans, Canadians, and Australians have been shifting for Brazil. Don't assume you can just walk across the bridge.
- Book two nights. One day for the Argentine side, one morning for the Brazilian side.
- Pack a waterproof bag. Not just a "water-resistant" one. An actual dry bag for your phone and camera. The mist at the Devil’s Throat is basically a localized rainstorm.
- Download offline maps. Cell service is spotty once you get deep into the national parks, and you don't want to be paying international roaming rates while standing in the middle of a jungle.
Understanding the location of Iguazu Falls on map isn't just about geography. It’s about knowing that you’re visiting a place where two countries share one of the greatest spectacles on the planet. Whether you're standing on the Argentine "stage" or in the Brazilian "front row," just make sure you’re actually there to see it.
