From Independencia, we hike another 30 minutes to the windy traverse the West Face past the “Finger” and continue to the “Cave,” a journey that about 2 hours 30 minutes. It should take 5 hours to reach Cave from Camp Colera.

After a rest at the Cave, we tackle the steepest part of the ascent—the Canaleta. The Canaleta is an 800-foot couloir leading to the summit ridge. The final stretch from the Cave to the summit can take an additional 2 hours and 30 minutes.

What is the Success Rate on Aconcagua?

When you arrive on the side of Aconcagua, it becomes all about the weather.  The reasons the summit success rate is 30% is mainly down to the challenging weather. The winds are unpredictable and challenging at the best of times.

While weather is a major consideration,  many factors like,  lack of physical preparation and acclimatization also play their part. The weather, specifically high wind are the reason the success rate is so low.

The summit Aconcagua is 6,962m/ 22,841 feet above sea level. At this height, the air pressure (and the amount of oxygen it contains) is less than half that at sea level. To be precise you are working with 41% of what is available at sea level. Climbing to the summit of Aconcagua has been said to be comparable to ‘working with only one lung’.

Reasons to Climb Aconcagua During the day

The main reason to be high on the mountain during the day is managing the cold temperatures.  The other main reason is to have visibility on more challenging terrain where there is potential for rock fall high on the mountain.

Our Approach to Summit Night on Aconcagua

With over a decade of experience summiting Aconcagua, our team has honed the ideal approach for summit night, ensuring safety and success. Weather permitting, we commence our ascent from Camp Colera.

Our strategy is grounded in thorough acclimatization, primarily achieved by spending ample time at lower altitudes, particularly having four nights in Base Camp and a full rest day at Camp 2.

We like to move for 1 hour then rest, then another hour then rest. We do this for 3 hours. Higher on the mountain we take breaks every 30 minutes and on the traverse and Canaleta we can stop  every few minutes to regain strength and oxygen to move forward.

Our schedule aims to reach the cave after 5 hours of hiking. We like to arrive there by 10am. We will rest and prepare for the final ascent to the summit of Aconcagua.

Navigating High Altitudes on Aconcagua

At around 3am it’s time to rise, prepare gear, and begin hydrating. We encourage gradual water intake, aiming for at least 2 liters before departure.

By 3:30am, a shallow breakfast awaits. It is important not to eat too much. After breakfast you need to prepare for the summit night.  It is important to refill your water supplies with boiled water for the upcoming night and day. Some climbers prefer carrying two Nalgene bottles (equivalent to 2 liters) plus a thermos with another liter for the summit attempt, though hydration levels should remain a personal priority throughout the journey to the summit and back to Camp Colera.

The canaleta on Aconcagua

Ascending Towards Aconcagua’s Summit

Around 5am, our ascent to the summit commences. Our pace targets a vertical gain of 150m/492 feet per hour. We will gain more than this in the first part of the summit night and less on the back end of the ascent to the cave and Canaleta to the summit of Aconcagua.  Maintaining a disciplined pace and routine throughout is important.

Each hour, we halt briefly to hydrate, snack, and attend to personal needs, ensuring efficient progress while insuring safety of the team.  As we approach elevations exceeding 6,600m/21,654 feet, more frequent stops may be necessary due to reduced oxygen levels.

The final push towards the summit, particularly the ascent through the Canaleta, demands focused breathing and steady progress. Upon reaching the top of the Canaleta, we will take multiple brief stops to catch our breath until we reach the true summit of Aconcagua.

Descending Safely from Aconcagua

Following a successful summit, our team regroups for the descent to high camp, approximately a 4-hour journey. Descending the Canaleta and crossing the traverse needs to be slow and steady and once we get across the traverse we can move a little quicker. Continually moving down remains crucial for safety so we can get back to camp by 5pm.

Upon reaching high camp, climbers are afforded the option for dinner and then time to sleep. We will try and sleep until early morning the follow day and then descend further down to Plaza de Mulas Base Camp 4,390m/ 14,403 feet. The descent to Plaza de Mulas, presents its own challenges, requiring resilience and determination.
