I finally made it to Iguazu Falls in August 2026 — I regret not visiting during my 2022 South America trip as it was a little out of the way. This time, I flew into Brazil and immediately crossed to the Argentina side first, spending 2 nights there, giving the Iguazu at Argentina side one full day before moving to the Brazil side for another night. The whole border crossing process was smooth thanks to private transportation that handled customs on both sides.

This place is absolutely massive — we’re talking about hundreds of waterfalls spanning nearly 3 kilometers. It’s split between Argentina and Brazil. Both sides offer completely different experiences. Let me break down what I learned.
Iguazu Falls Argentina vs Brazil: Which Side is Better?
For this trip, I enjoyed the Brazil side more. My experience was heavily influenced by one major factor: Devil’s Throat Trail was closed on the Argentina side due to flooding when I visited. This is the most impressive trail as it brings to really close to the bottom of the falls. This would have completely changed my opinion.
Here’s what I noticed:
The Brazil side gave me those “in-your-face” waterfall views — I mean, I got SOAKED. The main trail gets you incredibly close to the falls, especially at the Devil’s Throat viewpoint. Yes the Brazil side give you access to the other side of Devil’s Throat. It was more curated too, with better infrastructure in the park, buses to help you get around, and overall more tourist-friendly vibes.
The Argentina side offers more trails and different perspectives — you can see the falls from above, from below, and theoretically from Devil’s Throat walkway (when it’s open). However, it’s definitely rougher around the edges, less polished than Brazil, but also significantly cheaper. I’m talking accommodation, food, everything, in both the park and the broader town it is in.
Both sides are absolutely worth visiting if you have the time. If I had to choose just one and Devil’s Throat Argentina was open? Probably Argentina for the variety of viewpoints. But as it stood during my visit, Brazil delivered the more dramatic experience.
How Many Days Do You Need at Iguazu Falls?
Minimum 2 days — one day for each side. That’s what I’d recommend to anyone.
I spent 2 nights on the Argentina side and 1 night on the Brazil side, with 1 full day for each side in the park. Actually you probably just need 3-6 hours each.
Argentina side needs a longer day to cover the main circuits properly — Circuito Superior, Circuito Inferior, and the Sendero Verde connecting trail. If Devil’s Throat reopens, you’ll definitely want about 5-6 hours.
Brazil side can be done in as little as 2-3 hours. The main trail is about 1.5km, but you’ll want to take your time at the viewpoints because the views are insane.
Also, factor in border crossing time between the two countries — with private transportation, I managed to cross the border within 1 hour.
Argentina or Brazil Side of Iguazu Falls First?
I went Argentina first, then Brazil. In hindsight, I’d probably stay 2 nights in Brazil side instead.
Here’s my reasoning: Brazil side is more tourist-friendly with better accommodation options and infrastructure. Starting there eases you into the whole Iguazu experience. Then you head to Argentina for the adventure side — rougher, cheaper, more trails to explore. You can also absolutely go to Argentina side in the morning and return in the afternoon too.
The Brazil side hotels felt more comfortable and well-maintained. Argentina side was noticeably more budget-friendly but also felt a bit more… let’s say “rustic”.
Crossing the Border Between Argentina and Brazil at Iguazu
I arranged private transportation to handle customs on both sides, and honestly, it was worth every penny for the convenience. The driver knew exactly where to go, waited while I got my passport stamps, and got me through without any stress.
You can also take buses between the two sides — they’re cheaper but take longer. The bus stops at both customs points and you have to get off, get your stamps, get back on. It’s doable, just more time-consuming.
The actual border crossing process was straightforward. You need to get exit stamps from one country and entry stamps for the other. No visa needed for most nationalities (check your specific country requirements).
Iguazu Falls Argentina Side: Trail Guide
The Argentina side lets you see Iguazu Falls from multiple angles — from high up on elevated walkways, from lower down near the water, and theoretically from Devil’s Throat. The park, officially known as Parque Nacional Iguazú, is located near the border town of Puerto Iguazú, where most visitors base themselves for accommodation and meals.
There are three main circuits to explore, plus a connecting nature trail. You don’t need to book tickets online — I just showed up and bought tickets at the entrance. But if you’re visiting during peak tourist season (summer months in South America: December to March), check crowd levels online first.
Circuito Superior (Upper Circuit) — 1.85 km
The Upper Circuit gives you bird’s eye views of the cascades from elevated walkways. This is where you realize just how massive the falls system is — waterfall after waterfall stretching into the distance.
It’s mostly flat, so not too physically demanding. Perfect for starting your day before tackling the stairs on the lower circuit. The views are spectacular in a different way — you’re looking DOWN at the falls instead of up at them.
Circuito Inferior (Lower Circuit) — 1.75 km
The Lower Circuit gets you way closer to the waterfalls. More stairs involved, slightly more challenging, but absolutely worth it for the up-close experience.
This is where your camera gets a workout. The power of the water hitting the rocks, the rainbows in the mist, the sheer volume of water cascading down — it’s intense. I spent way more time here than on the upper circuit because I kept stopping to just… stare.
Garganta del Diablo (Devil’s Throat Walkway) — 1.1 km
Here’s where I got unlucky. Devil’s Throat was closed due to flooding when I visited, which was super disappointing because this is supposedly THE highlight of the Argentina side.
From what I understand, this 1.1km walkway takes you right to the edge of the most powerful section of Iguazu Falls — a massive U-shaped chasm where the water just POURS down with insane force. The walkway extends out over the river, getting you ridiculously close to the action.
Here is a photo of Devil’s Throat on Brazil’s side so at least I got some version of it.
Sendero Verde (Green Trail)
The Green Trail is a short connecting trail through the subtropical forest — no waterfall views, just nature. It’s actually pretty decent for wildlife spotting.
I saw toucans here! Those massive colorful beaks are even more impressive in person. Also spotted some coatis (they look like a mix between a raccoon and an anteater) and various exotic birds.
It’s a nice break from the intensity of the waterfalls, gives you a chance to appreciate the surrounding ecosystem. Plus, way fewer crowds on this trail.
Iguazu Falls Brazil Side: Trilha das Cataratas
The Brazil side feels more curated and organized. There are buses in the park to help you get around, which is convenient when you’re already exhausted from walking.
The main highlight is Trilha das Cataratas (“Waterfalls Trail”), about 1.5km that ends at the big Devil’s Throat viewpoints. This is where I got that “in-your-face” waterfall experience I was looking for.
The trail gradually brings you closer and closer to the falls until you’re literally standing on a platform extending out over the water with Devil’s Throat roaring right in front of you. The mist here was INSANE — I was completely drenched within minutes. Bring a full waterproof setup or just embrace getting soaked.
In terms of the actual waterfall viewing experience? This was more dramatic and powerful. Argentina gives you variety and different angles, but Brazil gives you IMPACT. Standing at those Devil’s Throat viewpoints with millions of gallons of water thundering down right in front of you — that’s a moment I won’t forget.
Bring a rain jacket or poncho you’ll get hit with spray from the mist. It was wild seeing tourists completely soaked.
Where to Stay: Iguazu Argentina or Brazil Side?
If I had to choose one side for accommodation, I’d pick Brazil for comfort and infrastructure, Argentina for budget.
Brazil side hotels in Foz do Iguaçu, the Brazilian border city near the falls, felt more tourist-friendly, better maintained, and overall more comfortable. The town has a good selection of accommodations, restaurants, and amenities. It just feels more developed.
Argentina side (Puerto Iguazú) is noticeably cheaper — we’re talking significantly lower prices for hotels, food, and basically everything. But it’s also rougher around the edges. Less polished, more budget-oriented options.
I stayed on both sides and honestly, both have accommodation options near the park entrances, which is super convenient. If you’re doing both sides anyway (which I recommend), consider splitting your nights — 2 nights Argentina, 1 night Brazil worked well for me.
The Brazil side also has better restaurant options and nightlife if that matters to you. Argentina side is more laid-back, smaller town vibes.
Final Thoughts
In comparison, I enjoyed the Brazil side more just because I got ridiculously close to the falls — like, standing-in-the-spray-getting-completely-soaked close. The Brazil side’s Devil’s Throat viewpoint was insane.
But I also enjoyed the Argentina side for the variety of perspectives and trails. Being able to see the falls from above, from below, from different angles — that was cool. If Devil’s Throat had been open on the Argentina side, I think my opinion would be different because that walkway supposedly gets you even closer than Brazil.
That said, if you have 2+ days, both sides are absolutely recommended. They complement each other well — Argentina for exploration and variety, Brazil for that dramatic, powerful, in-your-face waterfall moment.
This is hands down one of the most spectacular natural wonders I’ve seen. The sheer scale of Iguazu Falls is hard to grasp until you’re standing there, surrounded by the roar of hundreds of waterfalls and clouds of mist. Definitely worth the trip, even if you have to cross international borders to see both sides! If you’re exploring more of the region, consider visiting Buenos Aires or the stunning landscapes of Patagonia.
