El Chaltén is in an ecoregion called ecotone, the transition between the steppe and the forest. The plain abruptly leads to huge rock formations with forested valleys crossed by rivers and streams.
The seasons are well defined during the year, summer is mild with average temperatures of 12ºC, days with many hours of sunlight, usually windy and moderate rainfalls. The winter is cold, with an average temperature of 2ºC, short days, little wind and sporadic snowfalls.
El Chaltén was declared «National Capital of Trekking”. In this way it is officially recognized adding value to the extraordinary combination of elements that are given in El Chaltén for mountain sports: a pristine and protected natural environment, numerous trekking circuits with varying grades of difficulty, dozens of climbing routes of very high technical requirements.
