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.

There are many wonderful waterfalls in the world, but some are plain difficult to get to. In contrast, Iguazu Falls (Argentina side) is relatively easy to travel to and makes an awesome experience. You can choose to stay at Puerto Iguazu (where you can take a short bus ride into the national park) or if you have some cash to... More

What can I say. This falls is enormous and natural. Good place for hiking. Ready to walk on lower and upper trails for better views. We saw from Argentina side. I did want to pay steep Brazilian visa fee of $300.00 each. This side view was good enough. There is a train which takes people to Devil's throat. Thanks

I had high expectations, after all this is off the beaten track. Many pictures online to show the majesty of the falls. Just a few pointers. Stay in hotel in or close to town, otherwise you will have to eat all you meals at your hotel or take taxis. You do not need a tour of the park, but they... More

The waterfalls are beautiful, but I also enjoyed seeing the monkeys, coati and butterflies! Weather was nice in November, and we needed sunscreen. Be careful with your cameras when close to the falls because the mist will get you wet.

Iguazu Falls is well worth the cost and time to get to and from Iguazu. Try to stay a couple of days if you can.

More if you want to do some activities such as motor boat, jingle walk or birds park. To make it in 1... More

Iguazu Falls is one of those bucket list must do's. The Argentine National Park provides a very unspoiled infrastructure of trails which allows you to see this absolutely spectacular natural wonder from every angle. Highly recommended!
