What is the date to climb Aconcagua? Everything you need to know
Planning an expedition to Aconcagua (6,962 m a.s.l. / 22,841 ft) is a task that requires technical precision and a deep respect for the mountain's cycles. Based on my personal experience after reaching the summit on 17 occasions, I can assure you that the window of opportunity to attempt the summit is strategic and dictated by the Park's safety logistics.
Calendario de Temporadas y Logística
El acceso al "Centinela de Piedra" se divide en dos grandes periodos regulados por la autoridad de aplicación:
1. Summer Season (Estival)
This is when most expeditions take place.
- General Period: From November 1st to April 30th.
- Summit Window: From December 1st to February 15th. This is the time with the best conditions and full coverage of medical and rescue services.
- Early Entry: You can enter during the last days of November for ascents, but for that, you must have the services of authorized local companies and request authorization 10 days in advance.
2. Winter Season
- Period: From May 1st to October 31st of each year.
- Requirements: To climb in winter, you need a special permit, insurance, and to demonstrate solid technical experience, as all activity must be regulated by a specific resolution.
Permits and Evacuation Insurance
Permits are nominal and non-transferable. Remember that, under no circumstances, are fees refunded once paid.
Evacuation Insurance: Your guarantee at altitude For any foreigner attempting the Ascent or Long Trekking, it is mandatory to have insurance that covers search, rescue, evacuation, and medical assistance. The policy must specifically cover air transport from the 5,600 m a.s.l. (18,373 ft) mark to the Horcones heliport.
I personally recommend Global Rescue; it is the one I suggest to my clients due to its proven response in high-mountain expeditions.
Trekking Options and Estimated Prices (2026/27 Season)
If you are not yet looking for the summit, you can experience Aconcagua at other levels.
Trekking to Laguna de Horcones (Beginner Level)
An ideal circuit for families that can be done all year round.
