(01) Overview
Ojos del Salado is the highest active volcano in the world, rising to 6,890 m / 22,608 ft over the Atacama altiplano on the border between Chile and Argentina. It is also the second highest mountain in the southern hemisphere, only some 60 m lower than Aconcagua.
"The Eyes of Salt" The name describes the round salt lagoons scattered across the flanks of the volcano, where flamingos feed on algae and krill. At 4,400 m, Laguna Verde is a thermal spring heated by the volcanic activity of the area — one of the best rest and acclimatization spots on the mountain. The crater lake near the summit, at roughly 6,390 m, is the highest lake in the world.
A remote peak in the driest desert on Earth The expedition unfolds entirely in the Atacama altiplano: salt flats, high-altitude lagoons, volcanic plateaus and roads that climb above 5,000 m. Vehicle access to Refugio Atacama (5,200 m) means the team can focus on acclimatization and the climb itself instead of long approach marches, while still operating in one of the most isolated mountain environments in the world.
Acclimatization strategy The 12-day itinerary is built around a progressive "climb high, sleep low" schedule: nights at Laguna Santa Rosa (3,700 m), an acclimatization ascent of Cerro Siete Hermanos (4,780 m), several nights at Laguna Verde (4,200 m), a carry day to Refugio Tejos (5,800 m) and a full rest day at Refugio Atacama before the summit push. Two extra days are reserved for the weather window.
Activities and Risks High-altitude mountaineering, snow and penitente travel, scrambling on rock ridges, 4x4 travel and refuge/tent camping. Risks include extreme cold and wind, intense UV exposure, altitude illness, isolated travel and loose rock.
Difficulty No previous technical climbing experience is required, but climbers must be in excellent physical condition and should have prior experience above 5,000 m. Summit day is long — 10 to 14 hours — on mixed rock, snow and a steep final headwall.
(02) Highlights
(03) Day by day
Arrival in Copiapó, team meeting and gear check. Drive up to Laguna Santa Rosa (3,700 m) in the Nevado Tres Cruces National Park. First night at altitude, hydration and rest.
Acclimatization ascent of Cerro Siete Hermanos (4,780 m) from Laguna Santa Rosa, applying the "climb high, sleep low" principle. Return to Laguna Santa Rosa for the night.
Transfer across the altiplano to Laguna Verde (4,200 m), a turquoise salt lagoon with natural thermal springs at its shore. Afternoon rest, hydration and evening soak in the hot springs.
Full acclimatization day around Laguna Verde with a trek on the surrounding slopes. Skills review: use of crampons and ice axe, rope handling and fixed-line technique. Overnight at Laguna Verde.
Drive by 4x4 up to Refugio Atacama (5,200 m), the mountain's advanced base. Camp/refuge setup, light walk around the refuge, hydration and early night.
Ascent to Refugio Tejos (5,800 m) to carry loads and acclimatize, then descent back to Refugio Atacama to sleep low. A key day for the body to adapt before the summit push.
Full rest and recovery day at 5,200 m: hydration, nutrition, gear preparation and weather-window planning with the guide team.
Pre-dawn departure from Refugio Atacama. Ascent past Refugio Tejos, across snow and penitente fields and up the final steep summit headwall — protected with a fixed rope — to the summit at 6,890 m. Views over the crater lake and the entire altiplano before descending back to Refugio Atacama.
Pack up the refuge and descend by 4x4 to Copiapó, with the option of continuing to the coast at Bahía Inglesa. Celebration dinner and a night at low altitude.
Reserve day held for weather, a second summit attempt or additional rest, depending on how the expedition unfolds.
Second reserve day. If not needed on the mountain, it is used for rest on the coast at Bahía Inglesa or optional excursions in the Atacama.
Transfer to Copiapó and flight back to Santiago. End of program.

(06) FAQ
No technical rock or ice climbing experience is required, but you should have prior experience above 5,000 m and be in excellent physical condition. Good options to build that experience beforehand are our Andes Climb (Cerro El Plomo) and Cotopaxi programs.
6,890 m / 22,608 ft. It is the highest active volcano in the world and the second highest peak in the southern hemisphere, only about 60 m lower than Aconcagua.
The program builds altitude gradually: Laguna Santa Rosa (3,700 m), an acclimatization ascent of Cerro Siete Hermanos (4,780 m), Laguna Verde (4,200 m) with a trekking day, Refugio Atacama (5,200 m), a carry day up to Refugio Tejos (5,800 m), a rest day, and then the summit push on Day 8. Days 10 and 11 are extra days reserved for weather or a second attempt.
The price depends on the size of your group and the dates chosen — larger groups get lower per-person rates. Contact us with your group size and preferred dates and we will send a detailed quotation.
Ojos del Salado is non-technical but the weather and wind are the deciding factors. That is why the itinerary includes two extra days — they significantly increase the chance of finding a good summit window.
