Ojos del Salado Climb Guide: Routes, Expedition Planning, Season, Gear & Safety
Ojos del Salado is the highest active volcano in the world and one of the great high-altitude expedition objectives in South America. What makes it different is that the climb is usually more about altitude, acclimatization, desert logistics, and vehicle-supported camp movement than about sustained technical climbing. This page covers the main routes, expedition style, season notes, essential gear, safety factors, featured videos, and guide companies for planning an Ojos del Salado summit.
Ojos del Salado Quick Facts
| Category | Details |
|---|---|
| Countries | Chile / Argentina |
| Range | Andes, Atacama region |
| Elevation | 6,893 m / 22,615 ft |
| Status | Highest active volcano in the world |
| Climbing style | High-altitude desert expedition with vehicle-supported camps and route-dependent scrambling near the top |
| Typical duration | Usually 10–18 days including acclimatization and desert logistics |
| Primary risks | Extreme altitude, dehydration, cold wind, desert exposure, weather shifts, and poor acclimatization |
Main Routes (Overview)
Route #1: Normal Route / Chilean Side
- Theme: the classic expedition line most teams use.
- Best for: climbers seeking the most established logistics and standard summit strategy.
- Character: vehicle-supported high camps, gradual acclimatization, long summit day, and usually non-technical climbing until the final upper mountain section.
- Important note: the route is often described as non-technical overall, but the final summit section can still feel exposed and serious at nearly 6,900 meters.
Route #2: Alternate Summit Variants
- Theme: less common options used by experienced teams and condition-dependent expeditions.
- Best for: climbers with strong altitude experience and flexibility around route conditions.
- Character: more dependent on current terrain, camp placement, and upper mountain conditions than the normal route.
- Note: most commercial teams stick to the established desert-access strategy on the Chilean side.
Why Ojos del Salado is so different
- It is one of the highest mountains in the world that is often approached as a mostly non-technical climb.
- That makes acclimatization, hydration, and camp logistics more important than technical rope systems for many teams.
- The Atacama setting creates a unique mix of dryness, exposure, and very high-altitude desert travel.
Access & Logistics
Typical expedition structure
- Most expeditions use multiple acclimatization peaks before the summit push.
- 4×4 vehicle access is a major part of the Ojos strategy and helps move camps progressively higher.
- Teams often sleep progressively higher while balancing recovery and hydration.
Planning notes
- Altitude strategy is the core of the expedition.
- Weather can still delay summit plans even in the dry desert environment.
- Although the peak is often called non-technical, the summit day is still a very serious high-altitude effort.
Best Time to Climb (Season Window)
| Season | Typical Conditions | Pros | Watch-outs |
|---|---|---|---|
| Main expedition season | Commonly climbed in the austral summer high-altitude season | Best odds for stable access, workable camp logistics, and summit windows | Very strong wind, deep fatigue, and severe altitude stress still remain central hazards |
| Shoulder periods | More variable access and less predictable upper mountain conditions | Potentially fewer teams | More uncertainty around weather, cold, and route timing |
Season planning tip
On Ojos del Salado, the best season is still only a starting point. The summit is usually won or lost by acclimatization quality and how well the team manages the desert high camps.
Essential Gear Checklist
Expedition clothing systems
- Cold-weather layering system for summit altitude and strong wind
- Warm gloves, face protection, and insulated summit layers
- Strong sun protection for dry high-desert conditions
- Sleep and camp systems that work well in cold exposed camps
Mountain essentials
- Mountaineering boots appropriate for very high altitude
- Helmet and route-dependent crampons or traction gear when conditions require them
- Hydration systems and electrolyte planning for extremely dry conditions
- Vehicle, camp, and communication logistics for a remote desert expedition
Most underestimated factor
The biggest mistake on Ojos del Salado is assuming that “non-technical” means easy. At nearly 6,900 meters, the altitude turns even simple terrain into a very serious challenge.
Difficulty & Safety Notes
What makes Ojos del Salado challenging
- Altitude: this is one of the highest non-Himalayan objectives in the world.
- Dryness: the Atacama environment increases dehydration risk and recovery stress.
- Wind: summit-day exposure can be severe.
- Fatigue: even gradual routes feel brutal after multiple nights at high camps.
- Summit finish: the final upper mountain can feel much more serious than the lower route suggests.

Frequently Asked Questions
Is Ojos del Salado technical?
Usually it is described as mostly non-technical, but the altitude and final upper mountain make it a very serious expedition objective.
What is Ojos del Salado famous for?
It is the highest active volcano in the world.
Why do teams use acclimatization peaks?
Because almost 6,900 meters is high enough that poor acclimatization can end a summit attempt before the technical difficulty even matters.
Why is Ojos a good expedition step?
Because it provides very high-altitude expedition experience without requiring the same level of technical climbing as many other giant peaks.
