Visiting Iguazu Falls Argentina is, quite simply, a must when you are in the country. No other waterfall in the world can compare to it – not even Kaieteur Falls, in Guyana, or Niagara Falls. Upon visiting Iguazu Falls, Argentina, Eleanor Roosevelt said “My poor Niagara.”

The waterfalls of Iguazu are made of a huge series of large and small waterfalls (the amount really depends on water levels) that you can admire from an incredible array of viewpoints. There are so many, indeed, that you can easily spend a couple of days visiting Iguazu Falls, especially if you decide to check out both the Argentine and the Brazilian sides.

Curious to find out more about this incredible place? Great! In this post, I will tell you everything you need to know to visit Iguazu Falls and make the most of it.

Some background information on Iguazu Falls

Iguazu Falls, or Las Cataratas del Iguazú in Spanish, are a UNESCO World Heritage Site and were named one of the Seven Wonders of Nature in 2011. They stretch for almost 3 km (1.86 miles) between the Argentine province of Misiones and Brazilian state of Paraná and they are the largest waterfall system in the world (though they are not the highest ones).

Iguazu Falls are constantly changing, and your experience there may change a lot depending on the year you visit, on the time of year you visit, and even on the day. Visit after some heavy rains, and some trails may be closed due to flooding, and some wooden paths even completely carried away by the water. Other times, there may be very little water.

When I visited Iguazu Falls Argentina, the flow of water was nice and strong, but it hadn’t rain in a while so I could walk all the trails and paths to all the viewpoints. But, since there was a lot of water, I still got (pleasantly) sprayed by the myst.

Best time to visit Iguazu Falls

The best time to visit Iguazu Falls is either the shoulder or the dry season, when you’ll have higher chances of clear skies but the temperatures are not as hot.

If you manage to go at the very beginning of the dry season, you should be able to see the falls at their fullest. I visited at the end of February and was very lucky, with 3 full days of sun – though it was actually very hot and humid. December to February is the rain season, but the other side of the coin is that you get to see the waterfalls in their full power. April to June is the dry season, and August and September are even drier and cooler.

Iguazu Falls receive tourists any time of year, but if you want to avoid the largest crowds don’t go in January or July, when it is peak summer season for the Argentines, or when they are having their winter break.

How many days to you need to visit Iguazu Falls?

You need at least 2 full days (and 3 nights) to Iguazu Falls. Both the Argentine side and the Brazilian side take a full day to visit, if not more. Yes, there are guided tours that go to both sides in one day, and there even are day trips to Iguazu Falls from Buenos Aires (more about that later) as a last resort; but this is a place that deserves to be seen at a a relaxed pace to be fully enjoyed.

Which side should you visit? 

If you are on a trip across Argentina, it only makes sense to visit Iguazu Falls in Argentina. However, if you are spending a few days in the region you should visit both sides. After all, Brazil is literally just across the river. Both Argentina and Brazil have national parks, but the experience you’ll be having in each of them is different.

If you have the option of visiting Iguazu Falls on both sides, see the Brazilian one first. If you only have time for one, opt for the Argentine side. The Brazilian side is very panoramic, and you’ll get perfect close up photos of the giant waterfalls.

But the Argentine side of Iguazu Falls is honestly much more fun. You’re literally IN the waterfalls. Trails take you above them, below them, under them (if you do the boat ride), and you can see a lot of wildlife.

The best trails and viewpoints in Iguazu National Park

You should factor in a minimum of 6 hours in the park, though 8 hours is perfect to walk all the trails at a nice pace and spend plenty of time to admire the views.

Once you are inside Iguazu National Park, in Argentina, you should take the Jungle Train (Tren de la Selva) which stops in 3 different places. Get off at the stop immediately after you get on, as this is the starting point of the Upper and Lower Circuits. These two are meant to take you around the park and to all the best viewpoints to fully enjoy Iguazu Falls. You should walk both of them.

The Upper Circuit is a shorter trail of less than one km (0.6 miles) that takes about one hour to complete. It has a wooden path that takes you to the top of the falls from where you can enjoy impressive views.

The Lower Circuit is a longer trail that will take you up to 3 hours, with several viewpoints. This is the trail you need to walk to catch the boat to San Martin Island and the boat that goes right under the waterfalls.

Once you have walked both circuits, go back to the train stop to get on the next train going to the Garganta del Diablo (Devil’s Throat). Once the train stops, take the wooden trail that leads to the waterfalls for about 1.2 km (one way) (0.7 miles). Along the way, you’ll be able to spot lots of turtles and at times even crocodiles in the water.

Factor enough time to visit the Garganta del Diablo, as it seriously is the highlight of Iguazu Falls. It’s massive, and the views is nothing short of amazing.

Another trail you can take is the Macuco trail, which goes all the way to Arrechea Waterfall. It’s a nice nature walk that should take you around 3 hours in total and during which you can admire lots of wildlife, and which takes you to a lesser visited part of Iguazu National Park where you can even swim in a natural pool.

I don’t recommend doing a helicopter tour. Argentina has banned them a few years ago, in an attempt to reduce the level of noise which causes noise pollution and disturbs wildlife. They are still available from the Brazilian side, but please refrain from doing it!

Wildlife in Iguazu Falls Argentina

Keep your eyes wide open when visiting Iguazu Falls Argentina, as you will be seeing lots of interesting wildlife. Birdwatchers will be in for a treat, as there are beautiful, colorful toucans and yellow-eyed bluebirds. You will also spot lots of coatis, which are quite similar to raccoons and not shy at all. Don’t feed them – though they will try to grab your food! And by all means don’t pet them: they may bite or scratch, and that hurts.

There are also lots of monkeys and supposedly also jaguars – though I haven’t heard of anybody who’s spotted these elusive mammals.

Guided day and multi-day Iguazu Falls tours

Visiting Iguazu Falls at night

One of the coolest things to do in Iguazu Falls is exploring it at night. The overall experience is incredible – animals are more active then; the waterfalls glow in the natural light of the moon and the starts, and the atmosphere incredibly eerie. This isn’t something that happens every day, but just when there is a full moon. So, if it is something you are interested in doing, make sure that your travel plans to Iguazu coincide with a full moon.

Night tours of Iguazu Falls take place for 5 consecutive nights every month. There are 3 departures – one at 7:45 pm, when you see the moon rising; one at 8:30 pm, when you see the final stages of the rising moon and the falls start being better illuminated by the natural light; one at 9:15 pm, which honestly is the best one as you this is when the falls will be better illuminated. All options include dinner at the restaurant inside the park.

Day trips to Iguazu Falls from Buenos Aires

You should at least a couple of days in Iguazu to fully enjoy it. However, if you are tight on time (ie you are on a business trip to Argentina) and only have a spare day, there are guided day trips to Iguazu Falls from Buenos Aires and that include round-trip flights and a guided tour of Iguazu National Park in Argentina.

It will be a very long day, with a very early departure (the flight lasts about 1 hour and 45 minutes) and it won’t be cheap. But if a day is all you have, it is still worth it in my opinion.

You can book your day trip to Iguazu Falls from Buenos Aires here or here.

Iguazu Falls Brazil
If you have time, also visit the Brazilian side

Going to the Brazilian side

If you are spending a few days in the region, you should also consider visiting the Brazilian side of Iguazu. Going there is very easy: buses depart from the main bus station in Puerto Iguazu and take you across the border. Once you are there, the driver will collect all passports for border control, and will get them back to you stamped.

What to wear when visiting Iguazu Falls Argentina

Wearing comfortable clothes and shoes is a must when visiting Iguazu Falls Argentina. However, it’s also very hot, and you’re likely to get wet – so perhaps wearing sandals is a better idea. Having said so, this is a list of essentials you should wear and pack when you visit Iguazu Falls:

  • A pair of good walking sandals, best if they have good grip and traction on the slippery paths;
  • A pair of shorts, best if quick dry. I recommend Kuhl Strattus Chinoicon;
  • A cotton t-shirt or a tank top. I love Kuhl Soniaicon;
  • A poncho – it folds really small and you can just wear it if the spraying from the waterfalls is extreme;
  • A quick dry towel to dry yourself after the boat ride;
  • A swimsuit – it’s a good idea to just wear this on the boat ride, so that your clothes don’t get wet (you can keep them in the provided dry bag) and it dries much faster than regular underwear;
  • A refillable water bottle – I am a fan of Lifestraw;
  • Sunglasses, sunscreen and a hat to protect yourself from the sun;
  • A good camera to capture amazing photos. Alternatively, a smartphone with an excellent camera will do;
  • A daypack, best if with a rain cover such as Osprey Daylite Plus.

Best Iguazu Falls Hotels

Puerto Iguazu is the closest town to Iguazu Falls in Argentina, so it makes sense to look for accommodation there – unless you want to opt for one of the expensive Iguazu Falls hotels inside the national park. As it is a very popular destination, there are lots of excellent accommodation options.

This is a selection of good Iguazu Falls hotels:

  • 125 Hotel is a very good hostels with a large dorm and several private rooms. There is a small pool where guests can relax, and a good breakfast is included in the price.
  • Falls Iguazu Hotel and Spa is the best option if you want to pamper yourself a little. Rooms are very large, modern and comfortable.
  • Jasy Hotel is close to the center of Puerto Iguazu and at a very short distance from the bus station. It has very large rooms – in fact, they are more like chalets; a good restaurants and bar; and a nice small pool.

Other useful information 

Much like for any other trip, I recommend getting a good insurance when visiting Iguazu and the rest of Argentina.
