Nevado Ojos del Salado is an active stratovolcano in the Andes on the Argentina–Chile border and the highest active volcano in the world at 6893m/22,615ft. It is also the second highest mountain in both the Western Hemisphere and the Southern Hemisphere behind Aconcagua and it is the highest in Chile.  Nevado Ojos del Salado could be translated as "Eyes of the Salty One", which describes it as being very snowy in the winter and salty with many lakes.

Due to its location near the Atacama Desert, the mountain has very dry conditions, with snow usually only remaining on the peak during winter, though heavy storms can cover the surrounding area with a few feet of snow even in summer. Despite the generally dry conditions, there is a permanent crater lake about 100m/330ft in diameter at an elevation of 6390m/20,960ft on the eastern side of the mountain. This is most likely the highest lake of any kind in the world.

The ascent of Ojos del Salado is mostly a hike except for the final section to the summit which is a difficult scramble that may require ropes. The first ascent was made in 1937 by Jan Alfred Szczepański and Justyn Wojsznis, members of a Polish expedition in the Andes.

Its name, meaning roughly “eyes of salt” in Spanish, comes from the enormous deposits of salt that, in the form of lagoons or “eyes”, appear in its glaciers. An international highway between Chile and Argentina runs north of the mountain.

Ruta Normal Route – Chile

  • February 8 - 19, 2024
  • December 8 - 19, 2024
Cost USD 7,995
Deposit USD 3,500

Day 01: ARRIVE COPIAPÓ – TRANSFER BY VEHICLES TO EL SALVADOR. You will be met at arrival to Copiapó and start your trip towards the highlands. The acclimatization process starts with a first night in El Salvador, a mining town where few tourists go. Accommodation will be rather modest but spending this first night at 2600m/8,530ft will enable us to proceed to a higher camp next day. Briefing with the mountain guide and equipment check. [no meals included]

Day 02: PEDERNALES SALT FLAT (drive 90 km/56 mi). We start driving east towards the Altiplano, we drive to our first camp next to Pedernales Salt Flat (3362m/11,030ft). We are now in the middle of the Chilean high plateau, the southernmost part of the Atacama Desert and home to a great diversity of wildlife such as flamingoes and foxes. In the evening, we take a short walk to the nearby lagoon where we see local flora and fauna and a large variety of birds. [B, L, D]

Day 3: CLIMB CERRO DOÑA INES (5070m/16,634ft) Early transfer by 4×4 to the base of Cerro Doña Inés (4500m/14,763ft). The climbing to the summit will take 5 to 6 hours round trip and allow for an amazing view of the surroundings. We descend and overnight at our base camp next to Pedernales Salt Flat (3362m/11,030ft). [B, L, D]

Day 4: TRANSFER TO LAGUNA VERDE Today we will drive along Maricunga salt flat, check in the Maricunga customs for our Ojos del Salado climb, and then keep going across the high plateaus to reach Laguna Verde. We set up a base camp nearby the lake, at the hot springs site (4350m/14,271ft). [B, L, D]

Day 5: CLIMB CERRO SAN FRANCISCO (6018m/19,744ft). We make an alpine start in the early morning and approach the mountain with the 4×4 (4800m/15,748ft). It is a full day climbing this beautiful mountain located at the very border between Chile and Argentina. The summit is at 6018m/19,744ft and we will need around 6 to 8 hours to reach the top. We descend and overnight at our lake-side camp (4350m/14,271ft). [B, L, D]

Day 6: LAGUNA VERDE REST DAY. Full day to rest and get ready to move to Ojos del Salado Base Camp. This extra day at 4350m/14,271ft is a great boost to your acclimatization process and should be fully used to recover from the Cerro San Francisco climb, hydrate and relax. Going for another hike on this day won’t be of any help to your body. We strongly recommend bringing books and music with you and just enjoy this rest day. Please note that the expedition leader may choose to skip this rest day according to the weather forecast in case a modification of the itinerary is needed to ensure the summit. [B, L, D]

Day 7: OJOS DEL SALADO – BASE CAMP (ATACAMA HUT) (drive 38 km /23 mi). Today we leave Laguna Verde and the international road to Argentina, heading to the foothill of Ojos del Salado. We drive off road, gaining altitude very quickly as we cross sand flats and steep rocky, sometimes snow-covered, slopes. Finally, we arrive at the Atacama refuge area, where we set up our base camp (5255m/17,240ft). [B, L, D]

Day 8: CARRY TO CAMP 1 (TEJOS HUT) (5825m/19,110ft). Today, we carry some equipment and food to Camp 1 – the Tejos Hut, following the sandy and rocky slopes. We cache our gear in the mountain hut, take a look around and descend back down to the base camp at the Atacama Hut (5255m/17,240ft). This hike is part of our acclimatization to maximize our chances of reaching the summit. [B, L, D]

Day 9: MOVE TO CAMP 1 (5825m/19,110ft). Today we move up to Camp 1 carrying the rest of the gear we will need for the summit. It is a short day we arrive early to get hydrated, eat and rest for the summit day. [B, L, D]

Day 10: OJOS DEL SALADO SUMMIT DAY (6893m/22,614ft). We make an alpine start (3 AM – 5 AM) depending on the wind and cold conditions and climb 8 to 9 hours up to the summit (6893m/22,615ft). The terrain may be snowy or dry. The climb includes an easy climbing/scrambling step just before getting to the summit. We will use our climbing harnesses and helmets and rope-up for this last part. From the top we have an amazing view over all major summits in the area, including Tres Cruces and Pissis. Going down we may stop for the night at Camp 1 or descend directly to base camp. [B, L, D]

Day 11: RETURN TO COPIAPÓ. Dismantle of camp and tents, organize gear and packing, load equipment and get the vehicles ready to go. Then we drive back to Copiapó, where we arrive 6 hours later. Transfer to Hotel Atacama Suites Copiapó (4 star) or similar. [B, L]
