Aconcagua, South America’s tallest summit, is revered by experienced climbers as a challenging feat of expertise and perseverance. It serves as an impressive starting point for those seeking to conquer the world’s highest peaks.



The Aconcagua climbing season is in full swing, drawing in adrenaline-fueled climbers and trekkers seeking the ultimate challenge. With favorable weather conditions lasting until March, this is the ideal time to conquer the 22,837 feet/6,961 meters behemoth. Towering over all other mountains outside of the Himalaya and Karakoram ranges, Aconcagua demands respect and determination from those who dare to attempt it. As the loftiest peak in South America, it stands among the elite Seven Summits and is revered by expert mountaineers as a true test of skill and endurance. For those brave enough to tackle this daunting summit, Aconcagua serves as an impressive first feat on their journey to conquer the world’s highest peaks

Jed Williamson, a longtime author on mountaineering and outdoor safety, and a member of Global Rescue’s Mountain Advisory Council, advised that Aconcagua is a great starting point for high-altitude climbing, as long as climbers properly acclimate. He cautions that while the mountain range offers relatively easier access and logistics, it should not be underestimated.

According to mountaineering authority Alan Arnette, the mountain is a relatively straightforward ascent as the approach is not long or difficult. However, the use of crampons and an ice ax are essential for this non-technical climb.

Those who dare to climb will encounter a variety of difficult weather conditions and breathtaking scenery. Towering over the Andes Mountains, Aconcagua reigns as the tallest summit in both the Western and Southern Hemispheres, soaring to an impressive 22,800 feet (6,960 meters). According to renowned mountain expert and member of Global Rescue’s Mountain Advisory Council, Ed Viesturs, the biggest mistake climbers make on this expedition is underestimating the necessary strength and endurance.

According to Viestures, climbing Aconcagua may not require advanced technical skills, but many people underestimate the physical and mental endurance needed for such a high-altitude ascent. However, being in top physical condition prior to attempting the climb can make it both more enjoyable and safer.

On Aconcagua, the weather is also a critical factor – it can be volatile, with freezing temperatures, strong winds, and sudden shifts in conditions. Adventurer, former military member, endurance athlete, chef, and member of Global Rescue, Amanda Burrill had successfully climbed Denali, Mount Kilimanjaro and Mount Elbrus before setting out to conquer Argentina’s Aconcagua in 2020. Despite her extensive experience, the climb up Aconcagua was surprisingly dry with minimal snow cover.

The absence of snow took her by surprise. She worried about the implications for the expedition, as she heavily relied on melting snow for drinking water and cooking meals. It felt almost like being in a parallel universe – freezing cold and windy, but no sign of any snow. However, Burrill managed to find an alternate source of water and ultimately reached the summit successfully.

According to Viesturs, the conditions on the climbing routes can change from one season to another. Generally, it remains dry up until the summit, but there have been instances where a snowstorm has brought in significant amounts of snow, requiring the use of crampons, an ice axe, and ropes. His team is always prepared for any type of weather that they may encounter during their climb.

According to Lukas Furtenbach, who runs Furtenbach Adventures, the upcoming climbing season in 2023/2024 will likely be wetter and warmer than usual. Due to a powerful El Nino, there is likely to be more rain and snow at higher elevations, along with warmer temperatures that could cause the snowline to rise. Climbers should be ready for changing weather conditions, particularly at higher altitudes.

Before attempting to climb Aconcagua, it is crucial to plan ahead, obtain necessary permits, and seek the assistance of experienced guides or mountaineering companies. According to Williamson, approximately 80 percent of the 4,000 climbers who take on Aconcagua each year are part of a guided expedition. With the easing of post-pandemic restrictions, Viesturs predicts that there will be less overcrowding on the mountain following an initial surge in visitors. He expects that the number of climbers will return to normal levels, possibly slightly lower than previous years.

According to Furtenbach, Aconcagua is an ideal place to prepare for mountain climbing. It provides a great opportunity to hone skills like self-management and staying warm and hydrated. However, it should not be underestimated; as a tall mountain, it presents numerous challenges for experienced climbers.
