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.

Visited in full flood in Jan 1977 as a young backpacker. Revisited with family in Dec. 2016 (half flood). Same impressive, memorable, mesmerising view. More expansive and closer up on Argentinian side - take Argentine cash, (about $US30 equivalent) for entry. Take free train (early) to "Devils Throat" from station near entrance. All walks (about 5km) have some descending and... More

Went to niagara last year and have to say these falls are way better. Still lots of people around but you'd have to expect that given the awesome beauty of the place. We walked the upper trail first and were blown away by the falls. When we went on the boat and the bloke drove into the falls it was... More

This is one of the best experiences nature has on offer. Breathtaking falls walks right across the many falls on the Argentinian side of the falls. The volume of water and the beauty of they many different falls are truly amazing. Hard to beat this in the world.

Absolutely amazing waterfalls - no need to book a tour, just get the local bus from the central bus station. We spent hours here - start early. The Brazil side is also worth a visit but you don't get right under the falls as you can here. Well mapped out park.

I visited with my girlfriend and we were both absolutely blown away, not only by the falls themselves-which are mind blowing- but by the organisation, information and the care given to conservation. The only thing I would mention, is that the gran aventura is quite expensive. It's around forty pounds for five minutes under the waterfall, ten minutes ride down... More

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
