What You Need to Know Before Climbing Aconcagua: Tips for Success

Aconcagua, standing at an impressive 22,841 feet (6,962 meters), is the highest peak in the Southern Hemisphere and a coveted summit for mountaineers worldwide. Located in Argentina, this "Stone Sentinel" draws climbers eager to test their limits. In this episode of Finding Elevation, we explore everything you need to know before taking on Aconcagua—one of the Seven Summits.

The Aconcagua Climbing Experience

Aconcagua’s climbing season runs from November to March, which is summer in South America. While it may not require technical climbing skills, the challenges of high altitude, weather, and carrying heavy gear make this mountain no walk in the park. The mountain’s most popular routes—the Normal Route and the 360 Route—offer distinct experiences for climbers.

The Normal Route: Known for its low technical difficulty but grueling length, this 42-mile route can take up to three weeks from start to finish. With a success rate of around 50%, preparation is key.

The 360 Route: A more gradual approach to acclimatization, this 64-mile route is longer and takes more time but offers a more solitary experience due to fewer climbers.

Challenges to Expect

Aconcagua presents several challenges, from extreme weather conditions to the physical demands of the climb. Temperatures can drop to zero Fahrenheit (or lower) at the summit, and wind gusts reach up to 100 miles per hour. Precipitation is generally low, but snow and quick-changing conditions are always a possibility.

One key challenge is managing heavy packs, as climbers are often required to carry their gear across rocky terrain. For those looking for relief, porters are available to help, carrying up to 20kg of gear for a fee, making the ascent a bit easier.

Gear and Preparation

Climbers should be prepared with the right gear, including crampons, an ice axe, and a harness—although technical skills aren’t required for Aconcagua. It's highly recommended that you gain experience with high-altitude climbs in locations like Ecuador or Mexico before attempting Aconcagua.

Training Tip: Focus on building strength and endurance. Practice ascending and descending rocky terrain with a weighted pack. If you live in a flat area, use urban environments or gym exercises that simulate unstable terrain to prepare for the demands of Aconcagua.

Mental Preparation

Beyond the physical challenges, Aconcagua requires strong mental resilience. Expedition-style climbing involves long days, tough conditions, and sometimes little sleep. Being comfortable with discomfort is key to success. Planning ahead for challenges—whether it's managing homesickness or handling harsh weather—can make all the difference.

Mindset Tip: Approach each setback as a learning opportunity and mentally prepare for the stressors of being in a remote, high-altitude environment.

Nutrition and Hydration

Fueling your body is crucial during the expedition, but appetite often decreases at high altitudes. Reframing food as fuel rather than a choice will help keep you energized. Hydration is equally important, as the combination of high altitude and physical exertion can quickly lead to dehydration.
