Heading to an extreme environment like Aconcagua for two weeks is no easy task. Having the right gear for your Aconcagua expedition is a serious component to success and a small error could quicky turn you around.

When you’ve been training a long time, and you’ve invested a lot of money, not only is that not the idea, but it’s also not safe! Here’s a thorough list to get you started.

You’ll face diverse and extreme climates while on your expedition to Mount Aconcagua.

 

The first couple days trekking into base camp will have heavily beating sun during the day (ex:15C/50F), but chilly nights. At base camp, 4300m/16,000ft, it will be cold to moderate temperatures during the day (ex: 0C/30F) and but cold nights / mornings. And, remember, in the mountain conditions can change in a second!! Heading from basecamp to summit, temperatures will drop quickly (ex: -15C/5F), and summit day even in mid january / middle of summer, can be -30C/-25F.

For example, when I checked the weather a couple days before beginning my Aconcagua expedition, it was forecasted to snow 30cm / 11inches for various days towards the summit. During our time on the mountain, our summit was pushed back due to winds of 70kph / 40mph. Others I know have climbed with no snow. That said, you need to smartly pack your layers and be prepared for it all!

Here’s a pretty comprehensive Aconcagua gear list, that serves for basically any mountain of higher altitude. When going to other mountains, the only things that will vary are how many of the base / mid layers you need or if the third layers are necessary.

Having the right equipment is essential to arriving to the top, and back down, safely and comfortably. Carrying the weight of what isn't needed makes you slower, more tired, and stresses your body. But you can't afford to not have something when it's needed.

Having the proper gear in your backpack is in direct coorelation to how well you planned.

Aconcagua Expedition Climbing Gear

  • Trekking Poles
  • Carabiners
  • Climbing Helmet
  • Ice Axe
