Created in 1937 and with a surface of 600,00 hectares you nail in Austral Andes of the Patagonia, the it counts, as its name says, with 356 glaciers; in addition to the region of El Chalten.
The lakes stand out in the park Viedma and Argentino. The second of them extends towards the west in two North and South denominated arms, where several glaciers finish, among them the Upsala and the Perito Moreno. The arms present/display characters of fiords, channels and bays. In 1981 the park was declared Natural Patrimony of the Humanity by UNESCO, with the objective to preserve for the future generations the testimony of the quaternary period. The most important vegetation of the region corresponds to the magallánico forest that surrounds the mountainous zone by glaciers, where the lengas and the notros adorns their branches in spring. The rest of the territory is surrounded by the steppe.
Between its fauna, it lodges species on the way to extinction like huemul, huillín, the dwarfed red deer pudu pudu, the guanaco and the hawk of Kleinschmidt.
The Hostería is characteristic Los Notros. There are terrestrial and lacustrine excursions.
EL CHALTEN (to the north of glaciers, 220 kilometers of El Calafate) This region of rocky bulks, presided over by the mount Fitz Roy (3.400 meters) alberga glaciers and cave paintings in the lake Roca, vestiges of the tehuelche culture. The tips escarped of El Chaltén are famous for climbing. Its name comes from the language tehuel that means " hill that smokes " by constant clouds.

GLACIERS
The glaciers of the Patagonia are born in the field of ice located to 1,800 meters on the level of the sea and measures 17,000 square kilometers. The glaciers are great rivers in solid state, formed from accumulated snow that is in constant displacement.

_ Glacier Perito Moreno (257 square kilometers, 30 kilometers in length, get to measure 70 meters on the level of the water, although he remains seated on the bed from the lake to 170 meters of depth) _ The most visited, but not therefore greatest. This ice language enters 250 kilometers in the mountain range. It presents/displays different range from blue colorations, result of the reflection of the light in the oxygen molecules that are catched in the compacted snow. He is the unique one of the park that allows that the visitors walk on him. It was discovered by the captain of the Chilean army Juan Rogers in 1879, the name received in 1899 of Perito Moreno in tribute to the great naturalist and Argentine explorer that, paradoxicalally never reached to see it in person. Until the decade of the 1990 was considered it like the only glacier of the world in advance process. The phenomenon of the rupture of its frontal walls summons to thousands of tourists. The last breakings were in 1970, 1972, 1975, 1977, 1980, 1984 and last the great rupture was the 17 of February of 1988. The time between a rupture and the following one she is variable, the experts say that it is not possible to be predicted when it will be the last rupture. One takes place when: the front of the glacier advances towards the peninsula of Magallanes, when closing itself the water-drainage of Brazo Rico, the level of the water raises between 13 and 25 meters; the water erodes the ice by its weaker point and causes the landslide of the dock and when the front of the glacier advances again on the channel until touching the coast, the process is reinitiated.
There are a viewpoint and footbridges.
