New - Climb Aconcagua with oxygen in 12 days

Climb Aconcagua with OXYGEN in half the time! A Game Changer concept!, "run" up the mountain, no more cold feet and hands, you will need a VERY strong he can keep up with YOU!

Overview | Full itinerary | Cost Includes

New! Increase your chances of getting to the top by using Supplemental Oxygen on summit day.

Advantages among many:

Himalayan Training, familiarize with the system, success and safety increase, frostbite reduction, shorter exposure to High Altitude, shorter summit window needed, possibly done on less time (10 days total), more enjoyable, etc

We are pioneering again a new alternative way to climb Aconcagua, with supplemental Oxygen on summit day. You will be able to lower the mountain to about 1,000 meters (3,300 feet) So basically the 7,000 meter Aconcagua will feel like a 6,000 meter peak, increasing significantly your chances of summiting, feeling more rested, it is safer and it can shave even 2 more days off our already fast and successful 12 Day speed ascent.

We will have Summit System and on Demand System Available, Clients will be trained on O2 use extensively at Base Camp and briefly in Mendoza by their Guides.

Price Increases significantly, since a porter will carry your bottle/s to High Camp and then down to Base Camp, O2 is expensive so are regulators.

Some people have criticized using O2 on Aconcagua, but they use Porters, Helicopters, etc, using O2 is an option, it makes the mountain safer and increases significantly the chances to summit.


Regular Aconcagua trips are 20 days long. We have shaved 10 days off the climb for you. You will still be able to successfully get a shot at the summit of Aconcagua, and in less time, because you will be on Supplemental Oxygen the toughest day of the climb. We still encourage the Hypoxico Training System and come pre acclimatized, if you wish to use supplemental O2.

Our new program also includes the following options:

Helicopter flight on the way out Cost is USD $1,800 for 3 people, so $600 each) Call or write us for more info.

Rental of Altitude Training System – Hypoxico Tent, ONLY available in the US, Canada, UK and some other European countries for shipping. If you live outside of the US & Canada you can buy the system.

What is High Altitude Training?

THIS WORKS! We have done some research and, IF YOU ARE WILLING TO SLEEP FOR 4-6 WEEKS AT HOME IN THIS TENT YOU WILL BE PRE-ACCLIMATIZED FOR ACONCAGUA. You can even watch a movie at home in your Hypoxico chamber, among other things, and regulate your elevation right where you are, increasing it week by week! More info here.

There are 3 main training methods used to gain the benefits of Altitude Training: Sleeping at altitude, Exercising at altitude, and Intermittent Hypoxic Training. More info here.

There are 3 main training methods used to gain the benefits of Altitude Training: Sleeping at altitude, Exercising at altitude, and Intermittent Hypoxic Training.

The following physiological reactions have been shown to occur:

  • Amplified pulmonary oxygen absorption
  • Boosted production of Erythropoietin Hormone (EPO) by the kidneys, stimulating generation of Red Blood Cells (RBCs) and enhanced oxygen transportation through the body
  • Increased capillarization for greater oxygen delivery to the tissues, muscles and brain
  • Enhanced production and rejuvenation of mitochondria (the cell's hub for aerobic energy production) and mitochondrial enzymes, allowing more efficient use of oxygen for energy production and superior enzymatic anti-oxidative defense.

Come to the mountain already pre – acclimatized, from the comfort of your home. Using an Altitude Training System – Hypoxico Tent you can acclimatize before you get to the mountain.
