What's the best time to climb Aconcagua?

The best time to climb depends on what kind of adventure you are looking for. 

Low season:  enjoy nature with fewer people

High season: increases your chances to have good weather conditions

Although the weather conditions are unpredictable, we usually have the best weather conditions in the High season to reach the summit. 91% of our expeditions reached the summit in the High season during the last 12 seasons. On the other hand, in the High season, we will find seven times more people in the Park than Low season. During the low season, 87% of our expeditions reached the summit in the last 12 years. In the seasons 2019/20 and 2021/22, we broke our own record and became the only company of the entire Park with a 100% summit success rate in two consecutive seasons, which means all of our 42 open expeditions reached the summit in the season.

Low season: from Nov 19 to Dec 14   

High season: from Dec 15 to Jan 31

Low season: from Feb 1 to Feb 20

Note: Polish route opens on December 1st. Aconcagua Park may apply changes without notice.
