Aconcagua Since 1976

Back in 1976, Fernando Grajales Expeditions was granted the first official license to operate mountaineering services at Aconcagua. Its founder, the legendary mountaineer Fernando Grajales, applied the same concepts of safety and ethics to his company that he applied to his own climbing expeditions. In a few seasons, the company became a trademark of Aconcagua.

Four decades later, we are proud to continue breaking trails under the same clear Andean skies, ruled by the same transparent principles.

Today, Grajales Expeditions continues to be a family-owned local company, committed to our team and to our community. At the same time, we work to keep a global perspective regarding innovation and service standards. To us, “fair trade” means simply to do things fairly, as we always have. Our goal is to create safe and successful mountain experiences for our clients, whether they are mountaineers that utilize our fully-guided expeditions or international agencies that trust us with their logistics.

All departures are 100% guaranteed.
If we publish it, we run it.

Towering above the surrounding Andean peaks, the summit of Mount Aconcagua stands at 6.960 m – 22,841 ft

Mount Aconcagua is located in the heart of the Central Andes of Argentina and is part of the Parque Provincial Aconcagua in the Mendoza province.
It is the highest mountain in both the Western and Southern Hemispheres, the tallest peak on Earth outside of Asia, and the second of the Seven Summits, after Mount Everest.

An expedition to this legendary mountain involves:
– Hiking winding trails in pristine Andean valleys.
– Being part of the international community of mountaineers that gathers at base camps.
– Experiencing the unique atmosphere of the highest regions of the Earth with its powerful shapes and colors, and cool, thin air.
