Ojos del Salado Climbing Expedition: Top Outdoor Adventures Awaiting You

Ojos del Salado is one of the world's most sought-after high altitude objectives. At 6,893 meters, it is the highest active volcano on Earth and the second highest peak in both the Southern and Western Hemispheres. A guided expedition combines spectacular desert scenery, relatively non-technical climbing, and the opportunity to experience one of the Andes' most iconic summits.

The best time for an Ojos del Salado climb is between October and March, when temperatures are milder and weather conditions are generally more stable. Even during the climbing season, strong winds, freezing temperatures, and sudden storms are common at high altitude, so flexibility and proper preparation remain essential.

Excellent physical fitness is essential. Although the climbing is technically straightforward for most of the route, the extreme altitude makes the ascent very demanding. Most climbers prepare with endurance training and previous experience on peaks above 5,000 meters. Guides also recommend completing an acclimatization program before attempting the summit.

Previous high altitude trekking or mountain climbing experience is highly recommended. Most of the ascent involves hiking over volcanic terrain, but the final summit section typically requires a helmet, harness, and fixed ropes. Your guide will explain how to use the equipment safely if needed.

You'll need layered clothing suitable for temperatures well below freezing, insulated boots compatible with crampons, gloves, goggles, sunglasses, sun protection, a warm sleeping bag, and a large expedition backpack. Most technical equipment can usually be rented through your guide if arranged in advance.

The Argentina route via San Francisco Pass offers excellent acclimatization opportunities, quieter surroundings, and a gradual approach. The Chile route is shorter and more commonly used, making it a popular choice for climbers with limited time. Your ideal route depends on your experience, available days, and acclimatization strategy.

Acclimatization is one of the most important factors for a successful summit. Most expeditions spend several days gradually gaining altitude while climbing nearby peaks before the summit push. Proper acclimatization significantly reduces the risk of altitude sickness and improves your chances of reaching the top safely.

Yes. Permit requirements vary depending on whether you climb from Argentina or Chile. Your certified guide or expedition operator will normally organize permits, park access, transportation logistics, and any required border formalities before the expedition begins.

Although the standard route is not highly technical, climbing independently is not recommended because of the extreme altitude, remote location, rapidly changing weather, and complex logistics. A certified mountain guide improves safety, manages emergency situations, and helps maximize your chances of a successful summit.

Most expeditions begin in nearby towns such as Fiambalá in Argentina or Copiapó in Chile. During the climb, teams typically stay in mountain refuges, high camps, or expedition camps depending on the chosen route and itinerary.

Explore-Share partners with experienced local mountain guides who hold nationally recognized certifications. On Ojos del Salado, many Argentine guides are certified by EPGAMT, while Chilean guides commonly hold ACGM certification. These qualifications demonstrate professional training in mountain leadership, risk management, and high altitude guiding.

Many climbers extend their visit by exploring the Atacama region's colorful lagoons, high altitude deserts, hot springs, and nearby volcanoes. Popular acclimatization climbs include peaks around the San Francisco Pass, making the area an excellent destination for a longer Andean mountain climbing adventure.
