Mountaineering in argentina

Argentina is an exceptional destination for mountaineers seeking to conquer 6,000-meter peaks, offering some of the highest and most challenging climbs outside of the Himalayas. The crown jewel is climbing Aconcagua, standing at 6,962 meters, which is not only the tallest mountain in South America but also the highest peak outside Asia. Climbing Aconcagua is a prestigious achievement for any mountaineer, offering routes that range from non-technical treks to demanding technical ascents. The mountain’s varied terrain and majestic views of the Andes provide a truly unforgettable experience. Additionally, the high level of infrastructure and support available for Aconcagua expeditions, including experienced guides and reliable logistics, makes it a prime choice for high-altitude climbers.

Beyond climbing Aconcagua, Argentina's Puna de Atacama region is home to several other formidable 6,000-meter peaks that are less frequented but equally rewarding. Ojos del Salado, at 6,893 meters, is the world’s highest active volcano and offers a challenging climb with breathtaking desert and volcanic landscapes. Monte Pissis, reaching 6,793 meters, is another notable peak, presenting mountaineers with the challenge of navigating its remote and arid terrain. These peaks, along with others like Cerro Bonete (6,759 meters) and Llullaillaco (6,739 meters), offer a unique combination of high-altitude adventure and the solitude of less-traveled routes. For mountaineers looking to push their limits and explore some of the world's highest and most stunning peaks, Argentina is a destination that delivers unparalleled opportunities.

Generally the peaks offer no technical interest, but remote locations (in unique lunar landscapes) make them into interesting expeditions. 

The best time to climb in Argentina is during the austral summer, from December to March, when weather conditions are more stable.
For climbing Aconcagua, Jan/Feb is the tail end.

High winds are common always though.
