Aconcagua, the highest peak in the Americas, is a challenging destination primarily for experienced mountaineers. Accessibility is limited, requiring permits and often involving multi-day treks. Solo climbs are possible but not recommended due to the inherent risks; guided expeditions are common and provide essential support. The climbing season typically runs from November to March, with significant seasonal restrictions due to weather. Costs can vary widely, from several thousand to tens of thousands of dollars depending on the level of support. A typical expedition lasts two to three weeks, allowing for acclimatization and summit attempts. It is crucial to be in excellent physical condition and properly acclimatized to the altitude.
