Argentina Side of Iguazu Falls: Is It Worth Visiting?
Visiting the Argentina Side of Iguazu Falls: Is It Worth It?
Is the Argentina side of Iguazu Falls worth visiting? For many travelers heading to South America, that’s one of the biggest questions when planning a trip to see this famous natural wonder. After visiting both sides, I can confidently say that the Argentina side offers the most immersive experience.
Approximately 80% of Iguazu Falls is located in Argentina, with the remaining portion in Brazil. With more than 275 individual waterfalls, Iguazu is often described as the world’s largest broken waterfall system. While the Brazilian side of Iguazu Falls delivers sweeping panoramic views, the Argentina side of Iguazu Falls allows you to walk directly above, beside, and even beneath sections of the falls.
Exploring Iguazu Falls National Park Argentina had been on my bucket list for years, and I was thrilled to fly from Buenos Aires to Puerto Iguazú. If you’re planning the same route, here’s exactly how I visited Iguazu Falls from Buenos Aires.
In this guide, I focus specifically on what you can expect inside the park and whether the Argentina side deserves a full day of your trip.

Purchasing Tickets to Iguazu Falls National Park
Two Lines at Iguazu Falls National Park
When you arrive at Iguazu Falls National Park Argentina, you’ll likely notice two separate lines — one to enter the park and one to purchase tickets. It can be confusing at first, especially when crowds are heavy. It took me a moment to realize which line I actually needed first.
How Much Do Tickets Cost to the Argentinian Side of Iguazu Falls National Park?
As of 2026, international visitor tickets are typically in the range of AR$35,000–45,000. Due to Argentina’s changing exchange rate, the USD equivalent fluctuates significantly, so always check the official park website before visiting.
When I purchased my ticket, I waited about 20 minutes in line and the ticket agent asked to see my passport. Citizens of MERCOSUR countries receive discounted admission (based on category), so having ID on you matters.
Entering Igauzu Falls National Park
By the time I had my ticket, the entrance line had thinned out considerably. I was inside the park shortly after opening and ready to explore.
Getting Around Iguazu Falls National Park
The park does not provide paper maps, but there are large posted maps throughout. The layout becomes easy once you understand the structure:
Trails are paths that connect you to the viewing areas
Circuits are looped walkways that lead to platforms and viewpoints
To see everything efficiently, most visitors follow the three main circuits, using either walking paths or the park train.
The Iguazu Falls Train
The train is less “scenic” and more of a shuttle that connects stations inside the park. It’s included with admission and helps people cover distance, but it fills up quickly. I chose to walk as much as possible because I wanted more chances to see animals.
The Trails and Circuits at Iguazu Falls National Park
There’s an important difference between trails and circuits here. Trails get you from one area to another. Circuits are where the main waterfall viewing platforms are.
During my visit, I walked three circuits as well as the connecting trails. At the time of my visit, the Isla San Martin circuit was closed.
Sendero Verde (Green Trail) at Iguazu Falls
The Sendero Verde (Green Trail) is not a sightseeing trail. It’s the connector path that leads to the Upper Circuit and Lower Circuit. When you enter the park, you arrive near the Central Station area, and from there you can either take the train or walk this trail.
I chose to walk because the trains were already booking out far in advance.
Circuito Superior (Upper Circuit) at Iguazu Falls National Park
I started with the Upper Circuit (Circuito Superior) because I had read it was the least spectacular of the main circuits, and I wanted to build up to the best views.
This circuit gives you views from above the waterfalls. The walk is mostly flat with metal-grated pathways and a few stairs. The grating can be slippery at times, especially with mist in the air.
As I walked along the circuit, I could hear the water long before I saw it. Then suddenly, the falls came into view as I turned a corner. The Upper Circuit is designed so you look down and out over multiple sections of the waterfall system, with signs identifying different falls.
Salto Bossetti on the Upper Circuit
The highlight for me on the Upper Circuit was the Salto Bossetti viewing platform. The walkway brings you right to the edge so you can look straight down over the rushing water.
It took me about 90 minutes to complete the Upper Circuit at a relaxed pace.
Circuito Inferior (Lower Circuit) at Iguazu Falls National Park
The Lower Circuit (Circuito Inferior) offers a completely different experience. Instead of looking down from above, you are closer to water level, and in places you feel the power of the falls much more directly.
This circuit is longer and has more stairs and elevation changes than the Upper Circuit. The mist and spray are stronger here, and the walk feels more intense—especially in hot weather.
First View of Garganta del Diablo from the Lower Circuit
One of the things I remember most clearly is that the Lower Circuit is where I got my first view of Garganta del Diablo (Devil’s Throat.) It stays in view for a stretch of the walk, and it’s a great preview of what’s coming later.
Watching the Boats on the Iguazu River from the Lower Circuit
As I passed Isla San Martin, I had a great view of all the waterfalls from the Lower Circuit. I was amused by watching the boat tours go up the Iguazu River towards the waterfalls. Many of the boats go into Salto San Martin, soaking their passengers.
I later learned that it costs around $90 per person to ride the boat into the curtain of Salto San Martin.
While I did not take a boat tour on the Argentinian Side of Iguazu Falls, I did go on a boat tour on the Brazilian Side.
I have an entire page dedicated to my visit to the Brazilian Side of Iguazu Falls. This page also includes a narrative of my boat tour under one of the waterfalls.
Salto Bossetti from the Lower Curcuit
Toward the end of the Lower Circuit, there is an incredible view of Salto Bossetti. As I approached the platform, I could feel the spray, and it was amazing to stand that close and feel the force of the water.
It took me about two hours to complete the Lower Circuit.
Circuito Garganta del Diablo (Devil’s Throat) at Iguazu Falls
The most spectacular section of Iguazu Falls National Park Argentina is Garganta del Diablo, or Devil’s Throat. To reach it, visitors can either walk a long flat path or take the train to the final station. I chose to walk there and take the train back.
After walking out over the river on the metal walkway, the viewing platform comes into sight—and the waterfall is immense. The sound is overwhelming, and the mist is constant.
This is also the most crowded part of the park. I spent at least thirty minutes working my way toward the front railing to get the clearest view.

The Devil’s Throat Circuit is Not a Loop
Unlike the Upper and Lower Circuits, Devil’s Throat is not a loop. You must walk out and then retrace your steps back the same way. By the time I finished, I had walked over 10 miles during the day (according to my iPhone), and I was exhausted—but it was absolutely worth it.
Animals at Iguazu Falls
One of the things I looked forward to most was seeing wildlife inside the park, and it delivered.
Caiman
Less than an hour into my visit, I saw a caiman sunning itself near the riverbank. A guide nearby mentioned that sightings aren’t guaranteed, so I felt lucky.
Coati
Coatis are the most common animals you’ll see. They look like a cross between a raccoon and an anteater, and they are extremely bold around visitors. They’re especially interested in food—and they will take it fast if you’re distracted.
I was the victim of a coati theft. While I was changing my camera lens to photograph one, a brave coati snatched my sandwich.
Monkeys
On my walk toward the Devil’s Throat station, I saw monkeys in the trees, including a female with a baby clinging to her neck.
Other Animals at Iguazu Falls National Park
I also saw birds, fish, spiders, a large snail, and a giant turtle.
Iguazu Falls Tours
In my opinion, you do not need a tour to enjoy Iguazu Falls National Park Argentina. The circuits are well-marked, the layout is logical, and it’s easy to explore at your own pace.
That said, many travelers like guided visits or want to add on an experience like a boat ride. If you include tour links on this page, this is the right place to keep your affiliate paragraph (without changing your existing disclaimer language).
Argentina Side vs Brazil Side of Iguazu Falls
One of the biggest questions travelers ask is whether the Argentina side of Iguazu Falls is better than the Brazilian side. They offer very different experiences.
Argentina Side
Walk above and below the waterfalls
Multiple circuits and a full-day park experience
Above the falls view of the Garganta del Diablo (Devil’s Throat)
Larger portion of the falls (about 80%)
More opportunities for wildlife sightings
Brazil Side
Wide, panoramic views that show the falls as a whole
Typically faster to visit
Easier to get “postcard-style” photos in fewer stops
Below the falls view of the Garganta del Diablo (Devil’s Throat)
More crowded due to less viewing areas
If you like walking, exploring, and getting as close as possible to the waterfalls, the Argentina side has more depth. If you prefer sweeping views and a shorter visit, the Brazilian side is incredible too—but the experience is different.
Is the Argentina Side of Iguazu Falls Worth Visiting?
Yes — absolutely.
If you can only visit one side of Iguazu Falls, I recommend prioritizing the Argentina side of Iguazu Falls. The combination of the Upper Circuit, Lower Circuit, and Devil’s Throat gives you a level of immersion that’s hard to match. Add in the wildlife encounters and the sheer scale of the park, and it becomes one of the most impressive natural sights I’ve ever seen.
