July 14 , 2025 | News

Marmolejo

With its impressive 6,108 meters above sea level, Mt Marmolejo is a little-known yet highly coveted gem among mountaineers. Located in the Andes Mountains, right on the border between Chile and Argentina, it is the southernmost mountain in the world exceeding 6,000 meters, making it a true challenge for adventurers seeking to push their own limits.

Just a couple of hours from Santiago, Marmolejo offers a unique opportunity for those wishing to undertake a high-altitude expedition close to Chile’s capital city. This makes it an excellent option for acclimatization, especially for those planning more demanding expeditions on peaks like Ojos del Salado or Aconcagua.

Although Mt Marmolejo is not an extremely technical mountain compared to other Andean giants, it is not an expedition for beginners. High-altitude experience and excellent physical preparation are required, as altitudes above 6,000 meters always imply serious conditions. Weather conditions can also be extreme, with strong winds and temperatures that drop significantly at night.

The classic itinerary includes a series of intermediate camps to facilitate progressive acclimatization and reduce the risk of altitude sickness. Additionally, the landscapes are breathtaking, with views stretching from Chile’s capital to the snow-capped giants that dominate the range.

Marmolejo also holds deep cultural significance. For pre-Columbian civilizations, the Andes Mountains were not only a natural barrier but also a sacred place. At these heights, archaeological remains have been found, revealing the spiritual importance of these mountains to the indigenous peoples.
