Iguazú National Park was created in 1934 by the 12.103 law,and covers an area of approximately 67.620 hectares. It was declared a UNESCO World Heritage Site in 1984 owing to its beatifull landscapes and large biodiversity of the subtropical forest.
This natural sanctuary is located in the far NE of the Republic of Argentina. With large amounts of precipitation, warm temperatures (15ºC on average in winter and 30ºC in summer) and the thick vegetation acting as a windscreen, it experiences extremely high levels of humidity.
The Iguazú river flows for approximately 1320km until its outlet in the Paraná.
Its width generally varies between 500 and 1000m however within the park it broadens to 1.500 meters and it twists to the south, then back to the north, forming a huge U which contains the outlet. A sudden drop in altitude here is the reason for the impressive water falls which form the main attraction of the park.
In this large curved path, the rocky landscape fragments the river into a multitude of channels, each of these in turn become its own waterfall. This long fragmenting effect results in the fan of falls which gives the park its name.
The Park is reknowned for its natural heritage, which includes:
A native flora with over 2000 species including: ferns, bromelias, orchids, palms and many large species of tree which serve as scaffolding for an equally large variety of climbing plants. These in turn provides fruits which lure the local fauna such as coatíes and toucans to name a few examples.
450 kinds of birds, wich can often be observed in the open in the early morning and at nightfall You can likely easily see toucans urracas teros, parrot and the incredible vencejos. This last species is endemic to Iguazú Falls.
