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.

We spent 2 nights on the Argentinian side of the falls. The views were spectacular and well worth the long trip to get there. The restaurants/cafeterias in the park are poorly run. So make sure that you bring lots of water and food with you. Bring hats, sunscreen, insect repellent, a long sleeve shirt and a change of clothing -... More

Iguazu Falls is an unbelievable site to see. The waterfalls are magnificent and a wonder to behold. If you are a photographer, remember to bring a tripod, wide angle lens, lens cloths, and graduated filters.

Definitely worth visiting and there are some spectacular views and photo opportunities. The first part of the falls is accessible from the Sheraton whilst the second area can be reached by a free train service.

We visited both the Brazilian and Argentinian side of the falls. The falls are really magnificent! The sheer power of the water gushing all around is unbelievable. Really beautiful!

It's just breathtaking. Easily accessible using public transit. Go early so that you can take better pictures before the throngs of crowds swamp the area. Two to three hours should be ample time to see all the best views

An absolute must do! These waterfalls are a sight to behold. With somewhere close to 270 individual falls and three different walking trails there is a surprise / breath taking moment around every corner on each trail. My suggestion is to get there real early and have one person in your party go stand in line to board the train... More

When you stand over the waterfall's edge and feel the vibration of the earth around you you'll know it was worth going to. Then there's the views, the coatis, the nature the walks and of course the Argentine people that all make it just that much better

Iguazu falls undoubtedly has the longest/widest set of falls I have seen - Niagra pales into insignificance and Victoria falls have wonderful height and also best seen from two different countries. Start in Brazil and stay in the only hotel in the park - Belmond hotel das Cataras and experience the privilege of seeing Devils Throat etc before or after... More

We had a magical day. I suggest going over two days to Iguazu Falls- Argentina. So you can walk all of the trails and see everything. Go first to the Devil's Throat via train ( catch from the second station). Then head to the lower trail. Finish with the upper trial for some amazing views as the sun shines on... More
