From the helicopter, we looked down on the lazy Iguaçu River as it meandered its way through the dense jungle. In the distance, spray was shooting high above the trees, letting us know where we were going. Then all of a sudden, the river became a torrent, crashing over the cliffs in hundreds of spots. Seeing so many waterfalls coming from its source was one of the most spectacular things we’ve ever seen. Visiting Iguaçu Falls is a must on anyone’s trip to Brazil.
Iguaçu National Park
Iguaçu River forms a part of the border between Brazil and Argentina. Near its end, it falls off a tall, horseshoe shaped canyon to make one of the most magnificent settings in nature, Iguaçu Falls (Cataratas do Iguaçu). Although most of the falls are actually in Argentina, Brazil is said to have much more spectacular views, and we have to agree. To read our post from Argentina, click here.
As we walked down the ramp toward the first waterfall viewpoint, I had nervous butterflies in my stomach. I didn’t want to expect too much, but I couldn’t help it. As it turned out, my high expectations were too low. The view from the first lookout is spectacular. I was speechless. Richard had seen them before, and he was still stunned by their beauty.
In front of us was a large c-shaped cliff with dozens of waterfalls picking their way down the two-tiered drop. Dense vegetation and rocky outcrops made it look as if the water were desperately trying to find a way down. The scene was so perfect. And then I looked down the boardwalk and realized this was just the beginning.
The walkway follows beside the falls for a remarkable 1 ½ km. We walked slowly, stopping often to take in the scenery that changed as we made our way along the falls. A dozen waterfalls turned into 100 and then a staggering 275. Water was cascading at random intervals. Some were large and ferocious; others were narrow streams of water. Each on its own would have been a gorgeous site but all of them together make Iguaçu one of the most beautiful, if not the most beautiful, waterfalls in the world.
If I were a judge in a competition of most beautiful waterfall in the world, Iguaçu would get an A+++ for setting, design and execution.
At first, we were almost too distracted by the many waterfalls to notice the large number of colourful butterflies around us. Purple, red, blue and orange wings were fluttering around us as we walked down the path.
The highlight of the waterfall is a long, narrow, horseshoe shaped gorge where water gushes from both sides. The Devil’s Throat (Garganta do Diabo) has so much power that you actually can’t see inside because of the amount of spray of blocking the view. After spending well over an hour walking the length of the Iguaçu, we walked down a set of stairs and onto the long boardwalk that takes you close to the mouth of the Devil’s Throat.
Very quickly, we were soon soaking wet from the mist, but it didn’t matter; the view is much better than the mist is annoying. From the platform, you are surrounded by Iguaçu, and you can really feel its power.
We visited the Argentine side in 2026, once the pathway to Gargantua del Diablo was repaired. If you have time, you should really try to visit it from both sides, because you have a much better view of the Devil’s Throat in Argentina. For more information and pictures, visit our post Iguaza Falls, Argentina’s Natural Wonder.
It was amazing to watch daredevil swallows as they darted in and out of the powerful falls. They have nests in the rocks behind the cascades.
A viewpoint above the falls gives a better view of Devil’s Throat, but you still can’t see it fully. We knew we wanted a better look.
To fully realize the breadth of this waterfall, you must see it from above. It was from a helicopter that we were finally able to get a full view of this amazing natural beauty. The 10 minute helicopter ride began by following the calm, flat river as it gently flows through the dense jungle. In the distance, we could see high sprays of water letting us know where to find it.
Suddenly, the gentle river meets the canyon where it drops straight down the 80 m tall cliffs. Other parts of the river, though, look as if the water is desperately trying to avoid the canyon, going further and further downstream, seeking another way. Eventually, the river finally cedes to its outcome, creating a waterfall that is 2.7 km long with 275 individual falls.
From the helicopter, the view was incredible. We could see how the light plays with the spray, forming colourful rainbows.
Foz do Iguaçu
The city Foz do Iguaçu (Mouth of Iguaçu) is a busy, but nice city 20 km from the waterfall. Even though it’s the closest access to the falls in Brazil, its downtown does not feel touristy. It has clean, tree-lined streets with a lot of restaurants and shopping malls. There’s not a lot to do in town, but on its outskirts is the confluence of Iguaçu and Parana Rivers, which form the borders between Brazil, Argentina and Paraguay.
When we were waiting for the bus, we noticed the courteous city workers cutting the grass. They had a portable wall between them and traffic. We think it was to protect cars from debris from their weed-eaters.
How to visit Iguaçu Falls
The Brazilian side of the falls can be seen from Parque Nacional do Iguaçu (Iguaçu National Park) 20 km from Foz do Iguaçu. The park is open daily from 9 am until 5 pm. To get to the falls, you can hire one of the many tour agencies in town or online, but it’s very easy to go on your own. Taxis or Uber can drive you to the ticket counter. It’s also easy to take the public bus. Ask your hotel where the stop is for Bus 120 (R$5/$1USD). It leaves downtown every 20-30 minutes.
Your park ticket includes a bus that takes you to the walking trails. The first bus stop is for boat tours. We got off at the second stop, which is across from Belmond Hotel das Cataratas, so we could walk the entire length of the falls. If you don’t want to walk, you can stay on the bus all the way to Devil’s Throat. Entry fee is R$83 ($16 USD) for foreigners.
Other ways to see the falls include a helicopter tour or boat rides. We highly recommend taking the helicopter tour.
In 2026, we visited the Argentine side, where walkways take you right above the rivers, near their end, where they plunge over the cliffs. This includes an upclose view of the Devil’s Throat. (Note it is spelled Iguazú in Spanish). You can read more about this visit in our post, Iguazu Falls, Argentina’s Natural Wonder. Here’s a preview of that visit.
How to get to Foz do Iguaçu
The city of Foz is very accessible by plane, car or bus. The international airport is 14 km outside of town, and the bus depot (Rodoviária) is 6 km away. If you’re driving or taking a bus, it is 13 hours to São Paulo and 6 hours to Curitiba. Buses run frequently from the main bus terminal in Argentina’s Puerto Iguazu (1 hour).
When to visit Iguaçu
Rainy season is from December to March, so this is when the falls will have the most water, but the skies are more likely to be cloudy. Toward the end of the rainy season, the river and falls may be a brownish colour. Blue skies are more common between April and October, and the rivers are fullest in April and May. We visited in December and had a mix of rainy days and blue skies, but unbearable humidity.
Where to stay
Most people will stay in downtown Foz do Iguaçu. There are many restaurants and hotels in the area. If you want to splurge, though, stay at Belmond Hotel das Cataratas in the National Park. It’s right across from the first viewpoint, so you would be able to visit the falls multiple times and more easily go during the best weather.
