Aconcagua is the highest mountain outside of the Himalayas and the Karakoram range.
The mountain's name is derived from the Quechua 'Ackon Cahuak', meaning 'Stone Sentinel'.
The first recorded ascent was completed in 1897 by Swiss guide Matthias Zurbriggen.
The South Face of Aconcagua is nearly 3,000 meters tall and is considered one of the most difficult big-wall climbs in the world.
Despite its height, Aconcagua is not technically a volcano, though it has volcanic origins in its underlying rock formations.
The summit contains a significant amount of ice and snow, but due to low humidity, permanent glaciers are relatively small compared to other mountains of its size.
Archaeological discoveries, including an Incan mummy, have been found near the summit, suggesting indigenous people reached high elevations centuries ago.
The temperature at the summit is consistently freezing, often dropping to -30°C or lower even during summer months.
Aconcagua is the highest mountain in the Americas, reaching an elevation of 6,961 meters (22,838 feet) above sea level. Located entirely within Argentina's Mendoza Province, it is the highest peak in both the Southern and Western Hemispheres. The mountain is situated within Aconcagua Provincial Park, which protects its diverse high-altitude ecosystems and glaciers. Geologically, it is a non-volcanic peak formed by the subduction of the Nazca plate beneath the South American plate. The mountain features multiple glaciers, with the Ventisquero Horcones Inferior being one of the most prominent on its southern face. Climbing routes vary significantly in difficulty, ranging from the technically straightforward 'Normal Route' to the highly demanding South Face. High-altitude acclimatization is essential due to the extreme thinness of the air and rapid weather changes. The park attracts thousands of international mountaineers and trekkers annually during the peak summer season.

Prioritize a professional medical check and altitude acclimatization plan before attempting any trekking.
Carry high-SPF sunscreen and polarized sunglasses to protect against intense UV radiation at high elevations.
Ensure all gear is rated for extreme sub-zero temperatures and high-velocity winds.
Attempting to summit without proper high-altitude training or hiring an uncertified local guide.
Park access is strictly regulated and generally limited to the southern summer season between November and March; closed during winter due to extreme hazards.
Strict 'Leave No Trace' policies apply; all waste, including human waste, must be removed from the park.
