By the time we reached Mbiqua Falls the rain had arrived and photography was challenging. Note the hazy condition. I was really glad that I was using a zoom lens and did not have to swap lenses for different focal lengths. Be prepared. The weather can change rapidly. Other than that, the trails or circuits are wonderful and I highly recommend walking them to see different falls and viewpoints.
As mentioned in other tips, day two we walked the upper and lower circuits trails to see other falls at the park besides Devil's Throat. Hermanas and Bossetti Falls are well worth the walk. Be prepared for sunny or wet weather, although these trails were more protected by shade than the one to Devil's Throat.
Day two we walked the Iguazu Falls trails called Upper and Lower Circuits to see the other falls in the park. My wife went for the ride on the boat that approaches the falls and she described it as a thorough soaking. While she enjoyed it, I, a non-swimmer, also had a great time photographing the other falls on the trails. Photographers, I used all of my zoom lens range in the process, and, since it rained hard, I was really glad that I did not have to swap out lenses.
Day two of our visit to Iguazu Falls took us to the circuits to falls other than Devil's Throat. It started in sunshine and became a tropical downpour by the time we reached the tunraround point of our guided walk. A lesson to the wise: take poncho, small pack, water, hat, and be ready to protect your camera. I didn't and it was foolish. Still, these are wonderful falls and we were so glad we went to them. Photographers: bring the zoom lens and expect to use it.
Iguazu Falls consists of many falls, but the best known is Devil's Throat which we saw on our first day there. We stayed at the hotel in the park, walked ten minutes to the train, rode a few minutes to the circuit for Devil's Throat, and then spent the afternoon on the trail/boardwalk going to various viewpoints. Photographers: be prepared to shoot a lot. These are very photogenic and you will use all the ranges in your zoom lens. I did, wide angles to telephotos. Day one was sunny, so take water and wear the sunhat.
Hiding and showing the falls, in a game that we are invited to play and do accept with delight, the forest completes the ambiance, and gives dept, color and life to the site.
In Brazilian side there´s a circuit that shows the forest; here, I had no time to find out.
Here a powerful stream falling from your feet, there a placid river running slowly in the forest, the Argentine side of the falls is rich in delicious details, impossible to see from the Brazilian side.
However, the stronghest images are caught from the opposite Brazilian, so you should do as we did - to visit both sides.
Of all the waterfalls in the world, and i have seen many of them, Iguazu has to be the best. This is where they shot the movie, The Mission. The falls are 2700 metres long, divided by small islands but the horse shoe shape of the DEVIL'S THROAT is really impressive, as half the water flows violently over the 700m edge and drops 80m. It is now deservedly one of the new 7 wonders of the world.
I think that no one sees the falls only from the Argentin side - the big show is at Brazilian side. But it's easy to cross from one country to the other, so, staying in Brazilian Iguacu town, it only took us a couple of hours by bus, to stroll in the Argentin falls and go back.
However, don't miss the vertiginous sensation of walking over the falls, with the falling waters sliding under your feet.
Unlike the Brazilian side of the falls, there is a far more extensive trails system on the Argentine side of the falls. You do not get the panoramic views that the Brazilian side offers, but you are able to get quite close to the falls. One of the trails leads all the way to the bottom of the canyon, where it is possible to visit the island in the middle of the river, from which one gets a very different view of the falls. There is an entire row of falls that can not be seen from either Brasil or Argentina due to the hills on the island, and this island is the only place you can see them.
One trail goes all the way out to the end of the "Devil's Throat", but getting there requires a trip on the park's train all the way to the end of the line, and then a walk about 3/4 of a mile (slightly more than 1 km) to the viewpoint on a walkway set above the river.
The Argentina side certainly allows a different perspective of the falls than the Brasilian side does, and I do highly suggest that if time and money allow that you spend at least one day coming over here from the Brazilian side.
However, as the bridge between the two countries is quite far from the park entrance to both sides of the park, it really is better that you dedicate a day to one side or the other. It simply takes too long to get between the two sides of the park to try to include the border crossing and both sides in a single day.
Itaipu is a hydroelectric power plant on the Paraná River, located on the border between Brazil and Paraguay. The name ‘Itaipu’ means ‘singing stones’ in the local Guarani language.
It is one of the largest operational hydroelectric power plants in the world. The installed generation capacity of the plant is 14 GW, with 20 generating units of 700 MW each. In the year 2007, it achieved its generating record of 103 billion kilowatt-hours (kWh). In 2005, the power plant supplied 93% of the energy consumed by Paraguay, and 20% of that consumed by Brazil.
I hired a car and driver from my hotel in Argentina, and visited the Itaipu Hydroelectric Power Plant. I went on a guided tour of the power plant and it started with a brief documentary on Itaipu. The film was followed by a tour around the power plant, and this really showed how big a construction the power plant is.
We took the Macuco Safari on the Brazilian side for about $70US per person, unfortunately I hadn't heard about any boat tours on the Argentine side but it looks like it is more economical to do a boat tour in Argentina.
Although it is shorter in duration, it looks like Iguazu Jungle Explorer has a similar trip, the Great Adventure, for 90 pesos (about $30US). From the website, it looks like you can inquire about the tour at the Visitors Center or their head office.
The paths along the edge of the falls are a maze of narrow wooden bridges, going up and down, over the water or around it, allowing a fantastic walk really "inside" the falls.
Contrasting with the magnificence of the wide mouths seen from the Brazilian side, here you may see the fine details of the dozens of small cascades that compose the whole tremendous show.
Pay attention to the signs/maps in the park and follow them to the information booths to get a ticket for the boat trip up the river.
The boat will start ~1km downstream of the falls and bounce its way up the mild rapids and will get you wet from the spray of the falls from directly below.
They will give you plastic bags for your non-waterproof valuables, as well as a rain coat, but you will still get wet!
Iguazú Jungle Explorer had a office at my hotel (Sheraton) and through them I booked a boat trip combined with a jungle tour.
I (and around 10 other tourists) was picked up by an open truck, and driven through the subtropical jungle. The national park is very rich on flora and fauna, and our guide explained about the things we passed. Unfortunately we didn't see any wildlife, besides a couple of big spiders in the trees! In my opinion, a big open truck was not the best way to explore the jungle. I would have preferred a walk through the jungle, but don’t know if that’s possible…
Our truck ride ended at the riverbank, and we went abroad a small – but very fast – boat. Full speed towards the falls, where we from one of the pools admired the fantastic view from a distance. But we also came very close to the falls - very close! Practically underneath, and it was amazing to feel the power of the waterfall. Although we were wearing raincoats, we were soaking wet from head to toe. Remember to bring a plastic bag to keep your camera dry…
The boat trip on the Iguazú River was a great way to experience the waterfalls.
