Officially, the climbing season is between November 15th and March 31st of every year.
Our suggestion is to climb Mount Aconcagua between late November and late February. This is mainly because of two factors, first because of weather conditions. It is within this period when weather is warmer in the Austral Hemisphere and climate more stable on Aconcagua. Secondly, because it is when there is availability of all necessary logistics to go ahead with the climbs (mules, base camps supplies, porters, etc).
Before and after, the lack of visitors might make highly probably that you find no logistics. Regarding weather, large snowfields, strong winds and major snowstorms are a possibility.
The climbing season is divided into 3 sub-seasons:
Low season: from November 15 to November 30 and from February 21 to March 31
Mid Season: from December 1 to December 14 and from February 1 to February 20
High Season: from December 15 to January 31
The permits must be given in person to each visitor and only in Mendoza. Each climber must come in person to Mendoza city to get it. The permits can not be bought either at Puente de Inca or Punta de Vacas. The control of permisses is done in laguna Horcones (normal and south face), the same as in the Rio Vacas (Polish and Polish traverse routes) by the park-rangers. Anywhere inside the park, the permit or the receipt may be required to be shown.
Once in Mendoza, to get your permit follow this steps:
1. First you have to fill out a Registration Form
