The Iguazu National Park was created in 1934, with approximately 67,620 hectares/167,091 acres was declared "Natural Heritage to the Humanity" by the UNESCO in 1984 due to its scenic beauties and to the great biological diversity of the subtropical forest. This natural sanctuary, was declareted new 7 wonder of the world in 11/11/11. The Iguazu Falls are located in the Argentina's northeaster corner, bestowed with benevolent rains and temperatures (15ºC/59°F average in Winter and 30ºC/ 86°F average in Summer) brings about a very humid atmosphere almost windless due to the leafy vegetation canopy.

The Iguazu river has a total extension of 1320 km/ 820 miles until flowing into the Parana River, 23 km/ 14 miles after the waterfalls.

Inside the National Park, the river widens to about 1500 meters/ 0.9 miles and turns south, next it turns north, in the shape of a wide "U" where the river mouth presents the abrupt slump of soil which conforms the cataratas: a magnificent waterfall.

All along the above mentioned prominent curve, a proliferation of reefs, islets and prolonged islands provoke the fragmentation of the river in numerous branches. When the river reaches the cliff, each branch becomes a waterfall and together comprise the great Iguazu Waterfalls.

The Iguazu Falls appear grandiose and majestic in the Misiones forest dazzling visitors from all over the world. In celebration of all this beauty and unique attraction as from July 2001, a new concept of ecological tourism has been implemented within the Iguazu National Park, with an investment of 25 million dollars and service and facilities according to the international tourist demands, prioritizing at the same time the Park's care and preservation, a sample of the Paranaense Subtropical Forest declared Natural Heritage to the Humanity" by the UNESCO in 1984.

The fundamental objectives of this enterprise are the recover and conservation of the Waterfall Area, and the incentive to the present and future generations to renew the legendary admiration arisen by this wonderful masterpiece of nature.

Today, our visitors can enjoy safe and modern walkways from start to finish of the impressive falls and the Upper and Lower Circuits and the Devil's Throat, and facilities according to the natural environment such as the new Visitor Center and the alternative transportation of the Ecological Forest Train, which complies with international policies of accessibility and preservation of the World Union for Nature Conservation.

Absolutely fantastic - the enormity of the falls is quite overwhelming. Very busy in January. We did all the levels and the Devils Falls - really worth spending at least a whole day exploring the falls.

These falls are spectacular. Travelling there was not the easiest but so worth it. Beautiful pathways with railings and lookouts perched at the top. What a rush!

Iguazu Falls is truly spectacular and the trails are a real pleasure to traverse. Imagine walking across rivers and through forests. It makes it a really wonderful nature experience and Brazil and Argentina did an excellent job of preserving the natural beauty. I took the boat to the falls (Gran Adventura) and it was quite exhilirating. A once in a... More

Iguazu falls is simply amazing. The walk along the river on the 3 foot wide walkway is thrilling and amazing! Hard to imagine all that water! When you finally get to the falls after walking about a half mile on the walkway,, they are incredible. So beautiful. We were lucky as it was sunny so we saw a multitude of... More

This is one of the best natural sights I have ever seen, involving one huge cascade and a myriad of smaller waterfalls that add up to a sensational day out. But a lot of people think the same and it gets very busy, so time your visit. We stayed and visited from the Argentine side, from which there are basically... More

We flew to the Brazillian side of the Falls and were met by a guide who took us to the Bird Park and took us around the top of the Falls. This took about half a day. We then crossed over to the Argentine side of the Falls and checked into our accomodation and relaxed for the afternoon. The next... More

Along with a panoramic view from this side of the Falls we felt we were seeing the Falls from below. It was an incredible view and the their roaring thunder add to the drama. There is a walkway that takes you right out to them so you feel surrounded by there fury. The effect is quite surreal!!

The landscape itself is very beautiful and the Falls are amazing. Boardwalks are OK. At the top viewpoint, the best photo spot is reserved for invasive, insistent park photographers - a line forms right at the most important viewpoint in the park. The terrible downside is the park infrastructure: the trains to the top take too long to arrive and... More

WARNING!!!! If you go there you risk losing a reason to travel. This place is so great that nothing can compare to it and you know it when you're there. Every next place after this will be a disappointment. You can go to Brasilian and Argentinian side. Brazilian side has better views (IMHO) but Argentinian gets you closer to the... More

Iguazu has been on my bucket list for a long time and we finally got there. I have to say we were not disappointed. The falls were particularly active since there had been heavy rains over the preceding days. It was just spectacular. And kudos to the Argentine Park system for the trails/train/boardwalks that allow everyone to see the falls... More
