Iguazu (Iguaçu in Brazil) falls lies on the border between Brazil and Argentina, with Paraguay just a stones throw away.

The majority of the water falls lie of the Argentinian side (about 80% of the 270 waterfalls), but there are several falls next to the Devil's throat falls on the Brazilian side. 

While you get close to many water falls on the Argentinian side, in some cases so close that you get soaked wet by the falls (particularly the lower loop), but you can also experience this on the Brazilian side. The Argentinian side has 3 main areas - the Devil's throat which is the largest water fall in a fairly tight semicircle, then the upper loop falls, and finally the lower loop which passes many of the upper loop falls but also has some separate ones. When you enter the national park, you can take a railway or walk 3 kilometers to the Devil's throat, then return and walk the two loops. I can recommend doing all three as each has unique and wonderful views and experiences.

On the Brazilian side you need to take a bus 10+ kilometers to the first stop. You walk high above and alongside the lower river, with panoramic views of all the falls on the Argentinian side. You end up where you can walk out across an elevated walkway over some water falls towards the Devil's throat, getting soaked in the walk.

Unfortunately my days there were mostly cloudy, with the sun only occasionally peaking out from behind the clouds. I even had thunderstorms each day. So I missed getting any waterfall rainbows. But the whole area is spectacular none the less. I started with the Argentinian side as I stayed on that side. The next day I did the Brazilian side.

For photographers wanting to get smooth water  low effects - I used ND16 filters for the long time lapse exposures. I also occasionally struggled with poor light due to the heavy cloud cover.

My recommendation - do both sides, despite the hassle with crossing the border.

As always enjoy the copyrighted photos and if you want to use some for commercial purposes please contact me for a license.

There is a walkway on the Argentine top side edge of the Devil's Throat falls. It does not go near the centre of the falls - it would probably be near impossible to build a walkway there due to the mass of water flowing over the falls. The viewing platforms were very crowded with tourists, half of whom were trying to take 'selfies'.

The amount of water going over the falls is very impressive, particularly as it had rained a lot recently so the water levels were higher than normal. Unfortunately that also meant there was a huge amount of spray, which obscured part of the view.

In many places the spray was quite dense, and I had to wipe clean my lens after every photo. This was even more troublesome as I was taking many long time exposures of 1/2 to 5 seconds. Only about half the photos were usable.

The upper loop walk takes you along the top of the various water falls, sometimes almost on the edge of the drop. The experience of the masses of water going over the edge is impressive. The best views are near the start of the walk, as you see in the first photos. The last photo looks down onto the lower loop walk, you can read more about that experience in the next set of photos.

The lower loop is a shorter walk, but has more steps up and down. The most famous look out point is where the first photos below were taken, in the first one you can see a Coati prowling towards me (more on Coatis later). Due to recent rains, the falls had high water flows, so it was not possible to cross to the island viewpoint, that is between the look out and the falls in the photos. At least that was the park authority's excuse, because they still ran the boat tours to the bottom of the Devil's Throat falls!

The last 5 photos show the walkway that comes close to the last of the lower loop falls. Despite a rain jacket, I got completely soaked and my hiking shoes filled up with water while trying to get some of the photos. Luckily I came prepared with some spare clothes to change into afterwards. I was using an umbrella to shield my camera to stop the spray flying horizontally against the camera lens, quickly lifting it out of the way when I took a shot and then lowering it again while I wiped clear the lens. Only half the photos had minimal water droplets on the lens, the rest I could throw away.

I used a private driver to cross the border into Brazil and take me to the Iguaçu national park. This is the most convenient way to travel the about 30 kilometres and to (somewhat) avoid the long border control queues. The cost was about 30 USD for the day (there and back) so it was quite reasonable. I arrived around 11 am.

There was a moderate queue for the ticket office and a long queue for the national park buses (about 45 minutes) so come prepared to wait! The bus drives about 10 kilometres into the park before the main drop off point at the start of the panorama walk. I actually stayed on board and went to the end about 3 kilometres further along. I walked in the opposite direction to majority of tourists on the panorama path to the start and then turned around and walked back, taking photos along the way. At one point the sun threatened to come out, but the clouds quickly covered it up again.

The walk provides very good views of the many waterfalls but is further away than when you are on the Argentinian side. It is worth doing as you get a better overview.

At the end of the walk you approach a walkway over the falls which takes you out to a viewing point looking into the Devil's Throat falls, see fourth last photo. I took 3 photos looking downstream, but the amount of water spray was so high, I did not go all the way out on the walk way or I would have been completely wet again, like the previous day. And looking at the amount of spray, I don't think it would have been possible to get a good photo of the Devil's Throat.

The panorama point provides lookouts at three levels.

The first images were taken at the top of the falls, the last 3 images were taken at the base of the falls (the middle level) to the right of the Devil's throat, and lowest level takes you to the walkway that stretches out towards the base of the Devil's Throat falls. You can see the walkway in the second and third images.

The other photos look downstream from the upper level. There is also a panorama after this set of photos that I took from the upper level.

There is a lift that takes you up and down from the top to the middle level. I particularly like the images with the people in the photos I took at the middle level.

Due to the high water levels, the amount of spray was immense, so the extent of the views were more limited than I hoped for.

The coatis are the local fauna, photogenic subjects and thieves! They are not shy and will happily jump onto you and your bags in search of food.They have long claws and strong teeth so beware and avoid hand feeding them as they'll bite. The young lady in the blurry photos found out that they will jump and stick their snout in your bags.

The two panoramas were taken on the Brazilian side of the falls, the first from the upper level of the panorama point, the second about halfway along the panorama walk. Unfortunately it was impossible to get really clear views due to the immense amount of spray caused by the high water levels.
