Climbing Ojos del Salado 2026: The World’s Highest Volcano, the Atacama-Tejos Route & the Andes’ Second Summit
At 6,893 meters, Ojos del Salado is the world’s highest volcano and the second-highest peak in the Andes after Aconcagua. The Normal Route from Chile climbs through the driest desert on Earth, past the world’s highest mountain hut at Tejos Refuge, and finishes with a 30-meter fixed-rope rock pitch at 6,860 meters. The complete 2026 climbing guide.
Ojos del Salado occupies a unique position in world mountaineering. The peak isn’t quite the tallest mountain in the Andes — Aconcagua claims that title at 6,961 meters, 68 meters taller. It isn’t a technical climbing test piece — the Normal Route is largely a walk-up until the final 30-meter rock pitch. What Ojos del Salado is, uniquely, is the world’s highest volcano, the highest peak in Chile, and the second-highest summit in the entire Andes range. For climbers building toward Aconcagua or seeking the second-highest peak in the Western Hemisphere, Ojos del Salado delivers something genuinely rare. The peak combines serious altitude with moderate technical demands. The setting is one of the most surreal landscapes on Earth.
The mountain sits at 6,893 meters on the border between Chile and Argentina, in the heart of the Atacama Desert. The Atacama is the driest non-polar desert on Earth — some weather stations record annual rainfall in single millimeters, and parts of the region have effectively no recorded rainfall. The climbing approach drives through this otherworldly landscape: salt flats, multicolored mineralized hillsides, isolated lagoons frequented by flamingos, and dust storms that obscure visibility for days. By the time climbers reach base camp at the Atacama Refuge (5,200 meters), they’ve traversed terrain that more closely resembles Mars than any familiar climbing approach.
The Normal Route from Chile is the standard line used by 95%+ of climbers. The route ascends from Copiapó through Laguna Verde (4,300m, with thermal baths used for acclimatization) to the Atacama Refuge base camp at 5,200-5,260m. From there, climbers move to the Tejos Refuge at 5,837-5,900m — frequently described as the world’s highest mountain hut. Summit day begins at 03:00-04:00 from Tejos. The route climbs zigzag snow slopes to the crater rim. Climbers traverse past a frequently frozen high lake. The final 30-meter fixed-rope rock pitch at 6,860m reaches the summit. Total summit day runs 9-14 hours.

The name “Ojos del Salado” and what it means. Ojos del Salado translates from Spanish as “Eyes of the Salty One” or “Salty Eyes.” The name refers to the large salt deposits visible in the volcano’s eastern flanks. These vast white salt fields resemble eyes when viewed from certain angles, particularly from the Argentine side. The mountain takes its name from the nearby Río Salado (Salty River). Despite being officially shared between Chile and Argentina, the standard climbing approach comes exclusively from the Chilean side via Copiapó. The Argentine approach is significantly longer, more difficult logistically, and rarely used by commercial expeditions.
Why Ojos del Salado Matters in World Mountaineering
Ojos del Salado holds a precise position in global climbing that few other peaks share. The mountain combines four distinguishing elements: the world’s highest volcano title, second-highest peak in the Andes, accessible Normal Route at modest technical grade, and one of the most surreal landscape settings on Earth. Few mountains anywhere offer this combination, and the peak has become one of South America’s most sought-after high-altitude objectives.
The World’s Highest Volcano
Ojos del Salado is the world’s highest volcano, full stop. The peak sits 68 meters lower than Aconcagua (which is not volcanic) but stands taller than every other volcanic peak on Earth. Comparison peaks include Africa’s Kilimanjaro (5,895m), Russia’s Mount Elbrus (5,642m), Ecuador’s Cotopaxi (5,897m), and Mexico’s Pico de Orizaba (5,636m). For climbers pursuing the Seven Volcanic Summits — the highest volcano on each continent — Ojos del Salado represents the South American objective. The mountain is also classified as historically active, with the most recent significant volcanic activity occurring approximately 1,300 years ago. Minor degassing has been observed in modern times.
The Andes’ Second Summit
After Aconcagua at 6,961 meters, Ojos del Salado is the second-highest peak in the entire Andes range. The 68-meter difference between the two summits is small in absolute terms but meaningful in mountaineering classification. Climbers building toward Aconcagua often use Ojos del Salado as preparation — the altitude profile is similar, the desert setting builds tolerance for harsh conditions, and the technical demands prepare climbers for Aconcagua’s longer summit days. Conversely, climbers who’ve already summited Aconcagua often choose Ojos del Salado as the “second of two” — completing both peaks within the same expedition season satisfies a specific Andean mountaineering goal.
Chile’s Highest Peak
For Chile, Ojos del Salado is the country’s highest summit. The mountain is therefore part of any list of highest peaks by country, alongside Aconcagua (Argentina), Huascarán (Peru), Sajama (Bolivia), Chimborazo (Ecuador), and others. Chilean climbers regard the peak with significant national pride. The standard route is accessed entirely through Chilean territory via Copiapó, and Chilean operators dominate the commercial climbing market. The proximity to the Atacama Desert tourism economy means Chilean infrastructure — refuges, vehicles, guides, logistics — is genuinely strong.
The Atacama Setting
The Atacama Desert is the driest non-polar desert on Earth. Some weather stations record annual rainfall in single millimeters. Parts of the region have effectively no recorded rainfall in modern history. The climbing approach drives through landscapes that astronomers compare to Mars — vast salt flats, multicolored mineralized hillsides, isolated turquoise lagoons frequented by flamingos, and dust storms that obscure visibility for days. The Atacama also hosts some of the world’s most important astronomical observatories due to the exceptional sky clarity. Climbers spending 9-16 days on an Ojos expedition pass through scenery that exists nowhere else.
Ojos del Salado for the Seven Volcanic Summits. The Seven Volcanic Summits is the volcanic-mountaineering parallel to the more famous Seven Summits. Climbers pursue the highest volcano on each continent. Africa: Kilimanjaro (5,895m). Europe: Mount Elbrus or Damavand (5,642m or 5,610m). North America: Pico de Orizaba (5,636m). Antarctica: Mount Sidley (4,285m). Oceania: Mount Giluwe (4,368m). Asia: Mount Damavand (5,610m). South America: Ojos del Salado (6,893m). Ojos is the most demanding of the seven by significant margin — it’s the only one above 6,000m. Climbers completing the Seven Volcanic Summits sequence typically save Ojos del Salado for last because of its technical and altitude demands relative to the easier volcanoes.
Who Should Climb Ojos del Salado?
Despite its non-technical Normal Route, Ojos del Salado is among the highest commercial climbing objectives on Earth. The peak demands excellent acclimatization, prior high-altitude experience, and the willingness to commit to 9-14 hour summit days at extreme altitude. Honest pre-trip self-assessment matters considerably here.
Ojos del Salado Is Appropriate For:
Climbers with prior 6,000m experience. Climbers who’ve summited a 6,000m+ peak (Huayna Potosi, Cayambe, Mera Peak, Chimborazo, or similar) have the right foundation. The jump to 6,893m is meaningful but achievable.
Climbers building toward Aconcagua. Ojos del Salado serves as ideal preparation for Aconcagua. The altitude profile, expedition rhythm, harsh desert conditions, and summit day length all translate directly. Climbers attempting both peaks in sequence often do Ojos del Salado first.
Climbers pursuing the Seven Volcanic Summits. For climbers pursuing the volcanic version of the Seven Summits, Ojos del Salado is the South American objective and the most demanding of the seven.
Aconcagua veterans seeking variety. Climbers who’ve summited Aconcagua and want a different high-altitude Andes experience find Ojos del Salado’s volcanic character, Atacama Desert setting, and slightly different technical demands compelling.
Strong altitude performers with limited technical interest. Climbers who tolerate altitude well and prefer non-technical routes (versus harder technical objectives like Ama Dablam) often choose Ojos del Salado as their highest peak attempt.
Photographers and desert enthusiasts. The Atacama Desert setting offers visual content that exists nowhere else. Photographers willing to commit to the expedition timeline find their portfolio benefits.
Ojos del Salado Is Not Appropriate For:
Climbers without 5,000m+ experience. The jump from sea level to 6,893m without intermediate altitude experience carries elevated AMS and HAPE/HACE risk. Complete a major altitude trek (Kilimanjaro, EBC) and ideally a 6,000m climb before attempting Ojos del Salado.
Climbers expecting Western-style luxury support. The refuges (Atacama and Tejos) are basic. The expedition includes long 4WD drives across desert terrain. Comfort is limited compared to commercial Himalayan expeditions.
Climbers on rigid schedules. Multi-day weather windows can shut down summit attempts. Add buffer days. Operators typically include 1-2 reserve days in their itineraries.
Climbers with cardiovascular or respiratory health concerns. Extreme altitude is uncompromising. Climbers with heart, lung, or vascular conditions should consult specialized high-altitude medicine physicians before attempting Ojos del Salado.
Solo climbers without proper support. The remote setting, extreme altitude, and limited rescue capability make solo attempts genuinely dangerous. Commercial or partner-supported expeditions only.

The Standard Routes Up Ojos del Salado
The Normal Route from Chile handles 95%+ of climbers on Ojos del Salado. The Argentine side route exists but is significantly longer, more difficult logistically, and rarely used commercially. Variations on the Chilean Normal Route — different start dates, alternative acclimatization peaks, and minor route choices — account for most operator differentiation.
| Route | Country | Difficulty | First ascent | Usage |
|---|---|---|---|---|
| Normal Route (Chilean side) | Chile | Non-technical with 30m fixed-rope finish | 1937 (Szczepański & Wojsznis) | ~95% of climbers |
| Argentine Normal Route | Argentina | Longer; same technical grade | Various Argentine parties | ~5% of climbers |
| Northwest Face variations | Chile | Modern variations on standard line | Various | Rarely climbed independently |
Route 1: The Normal Route from Chile (Standard — 95% of climbers)
The Normal Route from Chile is the standard climbing line on Ojos del Salado, established by Polish climbers Jan Alfred Szczepański and Justyn Wojsznis during the first ascent on February 26, 1937. The route ascends from Copiapó through Laguna Verde (4,300m), the Atacama Refuge (5,200-5,260m), and the Tejos Refuge (5,837-5,900m) to the summit at 6,893m. The climbing is non-technical until the final 30-meter rock pitch at 6,860m, which features a fixed rope and requires basic rock-climbing competence at extreme altitude. The real challenge is altitude — at 6,893 meters, summit day operates at approximately 41% of sea-level oxygen partial pressure.
The Full Day-by-Day Progression (Standard 12-day Itinerary)
- Days 1-2 — Santiago to Copiapó: Arrive Santiago (most international flights). Internal flight or bus to Copiapó (550 km north). City briefing, gear check, supplies. Hotel night in Copiapó (390m elevation).
- Day 3 — Copiapó to Laguna Santa Rosa (3,755m): 4WD drive through the Atacama Desert. Visit salt flats and flamingo lagoons. First night at significant altitude. Acclimatization hike if conditions permit.
- Day 4 — Laguna Santa Rosa to Laguna Verde (4,300m): Continue driving deeper into the desert. Arrival at the turquoise Laguna Verde with its thermal baths. Two nights here for acclimatization. The thermal baths are a genuine highlight.
- Day 5 — Laguna Verde acclimatization day: Acclimatization hike to 5,000-5,200m and return. Possibly climb a smaller acclimatization peak. Hot bath at Laguna Verde in the evening.
- Day 6 — Laguna Verde to Atacama Refuge (5,200m): 4WD drive up what’s considered one of the highest and most dangerous roads in the world. Establish base camp at the Atacama Refuge. Rest of day for adjustment to altitude.
- Day 7 — Atacama acclimatization and load carry to Tejos (5,900m): Hike from Atacama to Tejos Refuge with gear, then descend back to Atacama. Approximately 3-4 hours each way at slow pace. Builds altitude tolerance and prepares Tejos for summit attempt.
- Day 8 — Rest day at Atacama or Laguna Verde: Some operators descend to Laguna Verde for better sleep at lower elevation. Others rest at Atacama. Both approaches work. Final summit day weather assessment.
- Day 9 — Move to Tejos Refuge (5,900m): Slow 3-hour climb from Atacama to Tejos with full summit gear. Early dinner. Bed by 19:00-20:00 to maximize rest before 03:00 wake-up.
- Day 10 — SUMMIT DAY: 03:00-04:00 wake-up. Climb zigzag snow slopes (5,900-6,400m). Long rightward traverse to crater rim (6,500-6,800m). Pass the frequently frozen high lake. Final 30m fixed-rope rock pitch at 6,860m. Summit at 6,893m. Descend to Atacama or Laguna Verde same day. 9-14 hours total.
- Day 11 — Reserve summit day: Buffer for weather or first-attempt failure.
- Day 12 — Return to Copiapó: Drive back through Atacama Desert. Hotel night in Copiapó. Celebration dinner.
- Days 13-14 — Travel to Santiago and home: Flight or bus to Santiago. International flights home.

Route 2: The Argentine Side (independent expeditions)
The Argentine side approach to Ojos del Salado exists but is rarely used by commercial expeditions. The route is significantly longer logistically — the road approach from the Argentine side is rougher, the desert traverse is more committing, and the climbing distance from base camp is greater than the Chilean approach. The technical climbing on the upper mountain is the same as the Chilean route. Commercial operators almost exclusively use the Chilean approach. Climbers attempting the Argentine side typically do so as part of independent expeditions or to combine Ojos with other Argentine peaks like Tres Cruces or Pissis.
Route 3: Combination Programs (Ojos + neighboring peaks)
Several operators offer combination programs that pair Ojos del Salado with neighboring high-altitude Andean peaks for extended expeditions. Common combinations include Ojos del Salado plus Tres Cruces (6,749m), plus Walther Penck/Cerro Tipas (6,670m), or plus the Argentine side peaks. These programs typically run 18-25 days and target climbers wanting maximum value from their travel to the Atacama region. The acclimatization profile of these programs is excellent — climbers establish altitude tolerance through the first peak before attempting Ojos del Salado as the trip’s highlight. Cost ranges from $5,000-$10,000 USD depending on number of peaks and operator tier.
Ojos del Salado Climbing History: From 1937 to 2026
For millennia before any climbing record, the Diaguita and Atacameño peoples inhabited the Atacama region surrounding Ojos del Salado. The Inca Empire later incorporated the Atacama into its territory, building roads through the desert and establishing ritual sites at high altitudes. Archaeological evidence shows Inca religious offerings at altitudes above 6,000m on various Atacama-region peaks — though specific evidence of Inca activity on Ojos del Salado itself is more limited than on neighboring volcanoes like Llullaillaco.
Polish geographer Aleksander Świtkiewicz conducted some of the earliest European exploration of the Ojos del Salado region in the late 19th century. The mountain was mapped and named during this period, though no ascent was attempted. Multiple Andean exploration expeditions through the late 1800s established the basic geography of the region without making summit attempts on the highest peaks.
The 1930s saw the most active period of Polish mountaineering exploration in the Andes. Polish climbers conducted numerous first ascents of Andean peaks during this decade, motivated partly by Poland’s status as a relatively new nation seeking international recognition through exploration achievements. Polish expeditions targeted multiple unclimbed peaks in the Argentine and Chilean Andes during 1934-1937.
The first recorded ascent of Ojos del Salado was completed by Polish climbers Jan Alfred Szczepański and Justyn Wojsznis on February 26, 1937. The Polish expedition established the line that became the standard Normal Route from the Chilean side. The ascent occurred during the late southern summer with relatively warm conditions for the extreme altitude. The first-ascent date in February has shaped operator scheduling ever since — most modern expeditions target the December-February window for similar conditions.
The first ascent from the Argentine side was completed in 1956 by an Argentine expedition. The route confirmed that Ojos del Salado could be climbed from either country, though the Chilean side approach remained significantly easier logistically. The dual-country approach options reflected the mountain’s geographic position straddling the international border.
The 1980s saw extensive Soviet and Czech climbing expeditions to Ojos del Salado. The peak became known in Eastern European mountaineering communities as a relatively accessible 6,800m+ summit. The Soviet expeditions in particular brought systematic acclimatization protocols and contributed to early commercial-style expedition templates that influenced later operator development. Czech expeditions documented the route extensively in mountaineering literature.
The 1990s saw rapid growth in commercial guiding on Ojos del Salado. Chilean operators including initial pioneer companies established Copiapó-based logistics for international clients. The Atacama Refuge was improved during this period, and the Tejos Refuge was constructed to serve as high camp. The first international companies (Aventuras Patagonicas, Alpine Ascents) began running commercial expeditions targeting both Aconcagua veterans and Seven Volcanic Summits pursuers.
The road to the Atacama Refuge became famous in 2007 when various automotive expeditions attempted high-altitude driving records on the slopes of Ojos del Salado. Modified Land Rovers and specialized vehicles drove to elevations above 6,000m on the mountain’s slopes — setting Guinness World Records for highest altitude reached by wheeled vehicle. The records prompted Chilean authorities to enact stricter access controls to prevent further mountain damage from vehicle attempts.
Through the 2010s, commercial infrastructure around Ojos del Salado expanded significantly. Copiapó accommodation and operator presence grew. Laguna Verde camping and thermal bath access were formalized. The Atacama and Tejos refuges received improvements. Annual summit numbers reached the hundreds, with international demand growing year over year. The Chilean tourism industry recognized Ojos del Salado as a major climbing destination alongside the country’s other natural attractions.
Chile closed to international tourism for most of 2020 due to the COVID-19 pandemic. Commercial Ojos del Salado expeditions paused. Limited operations resumed during the 2021 austral summer with significant testing and entry requirements. The 2022-2023 season saw considerable recovery toward pre-pandemic operations. Some Chilean operators emerged stronger from the pandemic period, having upgraded vehicles and refuge equipment during the closure.
The 2023-2025 seasons saw strong international demand for Ojos del Salado expeditions, with operators reporting full booking calendars for the December-February peak windows. Chilean and international operators including Adventure Alternative, Adventure Consultants, Aventuras Patagonicas, Alpine Ascents, XploreChile, Kuluar, and High Mountain Chile all run regular departures. February 2026 is notable for an Adventure Alternative attempt at a world record for highest marathon from the summit. The 2026 climbing season is currently active with departures running through March 2027.
The Chilean DIFROL Registration Requirement
Chile doesn’t charge a formal climbing permit fee for Ojos del Salado. However, international climbers must register with DIFROL. The agency name expands to Dirección Nacional de Fronteras y Límites del Estado (Chilean National Directorate of Frontiers and Borders). This registration is mandatory for any climbing activity in border regions and must be completed before arriving at Laguna Verde or the Atacama Refuge.
What DIFROL Is and Why It Matters
DIFROL is the Chilean government agency responsible for managing access to border regions and territorial waters. Because Ojos del Salado sits directly on the Chile-Argentina border, climbing activity falls within DIFROL’s jurisdiction. Registration is free but mandatory. Climbers without DIFROL registration can be denied access by Chilean police (Carabineros) at checkpoints between Copiapó and the climbing area. Most commercial operators handle DIFROL registration on behalf of their clients as part of standard logistics.
How the DIFROL Process Works
| Step | What Happens | Timeline |
|---|---|---|
| Application submission | Operator submits climber names, dates, peak details to DIFROL online system | 2-4 weeks before climb |
| Document verification | DIFROL verifies passport details and climbing plans | 5-10 business days |
| Authorization issued | Written authorization sent to operator and climber | Before arrival in Chile |
| Carabineros checkpoint | Authorization checked at police checkpoints between Copiapó and Laguna Verde | Day 3-4 of expedition |
| Independent climber process | Can be done directly with DIFROL but more complex without local agent | Allow 3-4 weeks |
DIFROL is mandatory, not optional. Climbers who arrive at Chilean police checkpoints without DIFROL authorization can be turned back from the climbing area. The registration is free but requires advance submission. Independent climbers can apply directly through the DIFROL online system, but the process is significantly easier through a Chilean operator who handles applications routinely. Verify with your operator that DIFROL is included in your package and that authorization is confirmed before you depart for Chile. Most reputable operators handle this automatically; budget operators sometimes leave it as the climber’s responsibility.
Ojos del Salado Summit Day Timeline: Hour-by-Hour from Tejos Refuge
Summit day on Ojos del Salado typically runs 9-14 hours round trip from the Tejos Refuge at 5,900 meters to the summit at 6,893 meters and back. Strong, well-acclimatized teams complete the round trip in 9-10 hours. Slower parties may take 13-14 hours or more. The combination of altitude, distance, and the final technical pitch makes this one of the longest commercial summit days in commercial mountaineering.
Standard Ojos del Salado Summit Day — Tejos Refuge (5,900m) to Summit (6,893m) and Return
The altitude reality of summit day. At 6,893m, summit day operates at approximately 41% of sea-level oxygen partial pressure. Climbers without prior 6,000m experience typically struggle significantly with the final 800m to the summit. The 30m rock pitch — easy climbing at sea level — becomes genuinely demanding at altitude. Climbers should not attempt Ojos del Salado without prior high-altitude experience. The acclimatization protocols built into commercial itineraries (Laguna Verde, load carries, rest days) exist for genuine physiological reasons. Skipping or rushing acclimatization significantly increases AMS, HAPE, and HACE risk on summit day.

When to Climb Ojos del Salado: Season-by-Season Analysis
November to March: Austral Summer (Climbing Season)
The austral summer is the only practical climbing window on Ojos del Salado. Weather is most stable during this period, though “stable” still means strong winds and -20°C summit temperatures. November is the opening shoulder month with potentially cooler conditions and lower crowds. December through February represents the peak window with the warmest temperatures (relatively speaking) and most reliable summit success rates. March is the closing shoulder month with shortening days and increasing weather variability.
April to October: Austral Winter (Off-Season)
The austral winter brings extreme cold, snow accumulation, and dangerous conditions on the upper mountain. Commercial expeditions do not operate during this period. Independent winter expeditions occasionally attempt Ojos del Salado but require extensive cold-weather expedition experience. The refuges typically close or operate at minimal capacity. Strong winds become extreme. Summit attempts in winter carry significantly elevated risk.
Weather Window Discipline (All Seasons)
Ojos del Salado experiences strong winds year-round due to its position in the Andes and exposure to South Pacific weather systems. Even in peak summer, multi-day weather windows can shut down summit attempts. Most operators build 1-2 reserve days into expedition itineraries to handle weather delays. The Atacama Desert receives effectively zero precipitation in any season, but wind alone can make summit days unfeasible. Climbers should expect to use weather buffer days during their expedition.
Climbing Ojos del Salado in 2026: Cost Breakdown
Ojos del Salado offers excellent value among extreme-altitude commercial climbing destinations. The combination of accessible logistics from Copiapó, basic but adequate refuge infrastructure, and competitive Chilean operator market keeps costs moderate relative to comparable 6,800m+ peaks elsewhere.

How Ojos del Salado compares to Aconcagua. Ojos del Salado ($3,500-$7,500 guided) is meaningfully less expensive than Aconcagua ($5,500-$10,000 guided) despite similar altitude objectives. The cost difference reflects expedition length (12 days vs. 18-21 days for Aconcagua), terrain accessibility, and refuge-based versus camp-based logistics. For climbers wanting maximum altitude achievement per dollar spent, Ojos del Salado delivers strong value. The peak’s status as the world’s highest volcano and second-highest Andean summit makes it a compelling alternative to Aconcagua’s longer, more committing expedition. Many climbers consider Ojos del Salado the better high-altitude experience overall.
Gear Checklist for Ojos del Salado
Ojos del Salado gear requirements emphasize extreme cold protection and high-altitude functionality. The 6,893m summit at -20°C with strong winds demands serious cold-weather kit. The final 30m fixed-rope pitch requires basic technical equipment. The desert approach adds dust and sun protection considerations not typical of Himalayan expeditions.

Frequently Asked Questions About Climbing Ojos del Salado
How tall is Ojos del Salado and where is it located?
Ojos del Salado rises to 6,893 meters (22,615 feet) on the border between Chile and Argentina in the Andes Mountains. The coordinates are 27.1095°S, 68.5413°W. The peak is the world’s highest volcano and the second-highest mountain in the entire Andes range after Aconcagua (6,961m, 68m taller). For Chile, Ojos del Salado is the country’s highest summit. The mountain stands within the Nevado de Tres Cruces National Park area on the Chilean side, in the heart of the Atacama Desert — the driest non-polar desert on Earth. The nearest city is Copiapó, Chile, approximately 250 km west by road.
How difficult is climbing Ojos del Salado?
Ojos del Salado is rated as a non-technical high-altitude climb until the final 30-50 meters. The standard Normal Route involves walking up scree and snow slopes at gradients up to 35 degrees, with one 100-meter snowfield section. The technical crux comes at approximately 6,860m where climbers must complete a 30-meter rock pitch with a fixed rope in place. The real challenge is altitude. At 6,893 meters, Ojos del Salado is among the highest peaks regularly climbed by commercial expeditions, with summit day oxygen levels around 41% of sea level. Successful ascents require excellent acclimatization, prior 6,000m experience strongly recommended, and the willingness to commit to 9-14 hour summit days in temperatures down to -20°C.
What’s the standard route up Ojos del Salado?
The standard route up Ojos del Salado is the Normal Route from the Chilean side, accessed from Copiapó via Laguna Verde (4,300m) and the Atacama Refuge (5,200-5,260m) base camp. The Atacama Refuge is reached by 4WD vehicle. From Atacama, climbers ascend on foot 3-5 hours to the high camp at Tejos Refuge (5,837-5,900m) — possibly the world’s highest mountain hut. Summit day begins at 03:00-04:00, climbing zigzag snow slopes to the crater rim, traversing the caldera edge past a frequently frozen high lake, then the final 30-meter fixed-rope rock pitch at 6,860m to the summit at 6,893m. Total summit day runs 9-14 hours round trip.
When is the best time to climb Ojos del Salado?
The Ojos del Salado climbing season runs from November through March during the austral summer. December through February offers the most stable weather and warmest temperatures (which still drop to -20°C on summit day). November is shoulder season with potentially lower crowds but more variable weather. March brings cooler temperatures and shortening days as the season closes. Most operators run fixed-date expeditions from mid-November through early March. The mountain’s location in the Atacama Desert means precipitation is rare year-round, but winter (May-October) brings extreme cold, snow accumulation, and dangerous conditions on the upper mountain.
How much does climbing Ojos del Salado cost in 2026?
Guided Ojos del Salado expeditions in 2026 typically cost between $3,500 and $7,500 USD per person for the standard 9-16 day program ex-Copiapó. Local Chilean operators offer expeditions from $2,500-$4,000 with full logistics including 4WD vehicle transport, refuge access, and Chilean IFMGA-certified guides. International operators (Adventure Consultants, Alpine Ascents, Aventuras Patagonicas) charge $5,500-$7,500 with smaller group ratios. International flights to Santiago add another $1,000-$2,000. Chile has no formal climbing permit required for Ojos del Salado, though DIFROL (Chilean foreign affairs) registration is required for international climbers.
What’s DIFROL and why do I need it?
DIFROL is the Dirección Nacional de Fronteras y Límites del Estado — the Chilean National Directorate of Frontiers and Borders. Because Ojos del Salado sits directly on the Chile-Argentina border, climbing activity falls within DIFROL’s jurisdiction. Registration is free but mandatory for international climbers. Climbers without DIFROL registration can be denied access by Chilean police (Carabineros) at checkpoints between Copiapó and the climbing area. Most commercial operators handle DIFROL registration on behalf of their clients automatically. The process requires submitting climber names, dates, and peak details to DIFROL online 2-4 weeks before the climb, with 5-10 business days for verification.
Do I need prior 6,000m experience to climb Ojos del Salado?
Yes — prior 6,000m+ experience is strongly recommended before attempting Ojos del Salado. The jump from sea level to 6,893m without intermediate altitude experience carries elevated AMS, HAPE, and HACE risk. Ideal preparation includes summiting one or more 6,000m peaks such as Huayna Potosi (6,088m, Bolivia), Cayambe (5,790m, Ecuador), Chimborazo (6,263m, Ecuador), Mera Peak (6,476m, Nepal), or similar. Climbers without 6,000m experience but with extensive 5,000m+ trekking (Kilimanjaro, EBC, Annapurna Circuit) can still attempt Ojos del Salado. They should choose extended itineraries that include intermediate acclimatization peaks like Tres Cruces or a sub-6,000m volcano before the main summit attempt.
How does Ojos del Salado compare to Aconcagua?
Ojos del Salado (6,893m) and Aconcagua (6,961m) are the two highest peaks in the Andes, separated by just 68 meters. Both are non-technical Normal Route climbs at extreme altitude. The differences: Aconcagua is a longer expedition (18-21 days vs. 9-16 days), has more developed camp infrastructure with multiple camps versus refuges, and faces more crowded conditions in peak season. Ojos del Salado has the world’s highest volcano distinction and a shorter, more accessible expedition with refuge-based logistics. Many climbers consider Ojos del Salado better value per altitude achievement and a strong Aconcagua preparation peak. The combined Ojos + Aconcagua in a single season costs $7,000-$12,000 for both summits.
What’s the temperature like on summit day?
Summit day temperatures on Ojos del Salado typically run between -15°C and -25°C, with -20°C being a reasonable expected value. Strong winds are standard year-round, with wind chill effectively dropping perceived temperatures considerably below the still-air figures. Climbers depart Tejos Refuge at 03:00-04:00 when temperatures may be near the day’s minimum. The summit at 6,893m is consistently cold even during peak austral summer (December-February). Heavy down parkas (-30°C rating), down mittens, balaclavas, and proper layering are essential — not optional. Climbers underestimating cold protection face genuinely elevated frostbite and hypothermia risk.
Is Ojos del Salado still volcanically active?
Ojos del Salado is classified as a stratovolcano with a long history of activity, though it has been largely inactive in recorded human history. The most recent significant volcanic activity is estimated at approximately 1,300 years ago, with minor gas emissions and degassing observed in modern times near the summit crater area. Volcanologists classify the peak as “historically active” but not currently erupting. Climbing the peak presents no meaningful volcanic risk — the activity level is far below thresholds that would affect summit attempts. The summit crater is a geological feature climbers traverse during the standard route, with no current volcanic hazards.
