The southernmost 6,000-meter peak on Earth — a true Andean expedition above Santiago

Your first true 5,000-meter summit — high above Santiago. A demanding yet accessible Andean ascent designed to build altitude confidence. The perfect gateway into serious high-mountain expeditions.

Why do this tour?

Marmolejo is not just about altitude — it is about commitment.

  • True 6,000-meter elevation
  • Long summit day (10–14 hrs total movement)
  • Remote terrain with minimal infrastructure
  • Technical high-altitude pacing

This expedition teaches:

  • Load management between camps
  • Glacier travel strategy
  • Hydration and altitude discipline
  • Mental resilience above 6,000 m

The reward is stepping onto a quiet summit overlooking Santiago, with panoramic views across the Andes toward Argentina.

Rising above the upper valleys of the Cajón del Maipo, Cerro Marmolejo stands as the southernmost 6,000-meter peak on Earth — a mountain that demands far more than its proximity to Santiago might suggest.

Its long approaches, exposed camps, penitentes fields, and sustained summit ridge create a true expedition atmosphere in the heart of the Central Andes. 

The ascent unfolds progressively from arid high valleys to glaciated upper slopes, requiring disciplined load carries, efficient camp logistics, and structured acclimatization.

 Above 5,500 meters, the terrain becomes increasingly committing: wind exposure intensifies, movement slows, and every decision — hydration, layering, pacing — directly affects summit success. The final ridge to 6,108 meters is broad yet relentless, demanding resilience and precise energy management in thin air. 

Marmolejo is not a guided “climb and go” objective. It is a compact high-altitude expedition that refines glacier travel systems, altitude strategy, and mental endurance above 6,000 meters. 

For mountaineers who have already stood on 5,000-meter summits and are ready for a quieter, more demanding Andean challenge, Marmolejo offers an uncompromising step into serious altitude.

An Unforgettable First
Ski Experience in Chile

Jan 06, 2026

Our first time in Chile — and our first ski experience in South America — became an unforgettable journey. The professionalism, warmth, and local knowledge of the guides made these days in the Chilean Andes truly exceptional. We came for the mountains, but we’ll remember the people most.
