Mount Ojos del Salado

At a height of 6893m, Mount Ojos del Salado is the highest mountain in Chile and also the highest active volcano in the world.

With it's venting fumeroles in the crater, just south west of the summit this is a climb like no other. Not only do we climb this majestic mountain but we also pass through the iconic Atacama Desert with its other-worldly terrain, lakes and wildlife. This is a true expedition of discovery into the heart of the high South American Andes.

This expedition gives a great opportunity to climb high with little technical difficulty apart from the summit rock tower, which is 30m of v.diff climbing with a fixed rope in place, and a very gradual acclimatization programme which gives everyone a good opportunity of reaching the summit.

The volcano is located in a unique desert environment of intense, deep, green lagoons contrasting with the colour of the desert and snow covered volcanoes above . At these lagoons its possible to see big flocks of flamingos, horny coots, many ducks,foxes and guanacos, who have all adapted to survive in this environment, with nighttime temperatures reaching – 25 c and winds over 130 kph.

Our expedition will be self-contained and in the real spirit of adventure, driving our own 4x4 land cruisers through the Atacama Desert to reach the base camp of the volcano. We will prepare our own food and act self-sufficiently on the climb.


The distance to the mountain from Copiapo is not that great, a few hundred kilometres, but we take several days to get there and appreciate the change in scenery. From Laguna Verde, the mountain is just a few hours drive away on dirt roads. The camps themselves are not spaced far apart, a few hours at most.


We use several campsites on the way into the mountain, and we use Laguna Verde as the base camp because it is sheltered and has amazing hot springs near the edge of the lake. The high camp at Refuge Atacama is just an area of open ground where we use tents and occasionally other companies will have set up base camps for multiple groups through the season.

The final hut at Tejos is actually a converted container with room for about 6 beds and anybody else sleeping on the floor. It is quite basic with no cooking facilities and an outside toilet, but at least it is dry and secure inside from the wind.

Travel insurance will need to be purchased by each team member to cover all costs associated with medical, rescue, equipment, cancellations etc. This should be purchased as early as possible to ensure cancellation coverage in case of any issues arising that cause you to cancel your trip.

The policy must be checked for validity in the regions through which we will be travelling and also for trekking/mountaineering to 6893m. Many specialist insurance providers have common peaks named on the policy description so it is worth contacting the company to check which is the appropriate level of cover. You should bring with you a copy of your policy and ensure your tent mate knows where you keep it. It is also worth bringing a photocopy of your passport and to keep it separate to your own documents just in case you lose your passport.


Mount Ojos del Salado - fitness and terrain

You will need to be physically fit and able to carry often heavy loads on rocky and difficult terrain. We suggest a six month training programme to prepare yourself, working particularly on cardio fitness, thigh and calf muscles, and plenty of hillwalking with a 15kg pack.

This expedition is about the same level as Aconcagua and harder than 6000m peaks like Island Peak. This is predominantly because of the weather, the wind can be very cold and this is a very dry debilitating cold. Good equipment is essential, but also a strong physical and mental capacity.

This is not a marathon or an exercise in strength, nor is it just an athletic challenge. We take a holistic view to climbing high mountains, with lots of fun and teamwork and opportunity to experience the scenery and the uniqueness of the location. Taken slowly, with good acclimatisation, a slow pace and plenty of water, food and sleep, this is a peak that is achievable for most fit people who have experience of self-management in the mountains.


This is not a technical peak and the climbing is never serious apart from one move just below the summit itself, but it does not require teams to be roped up.

Ojos is an old volcano so it has easy gradient slopes up to the caldera, which are snow covered and exposed. The caldera itself is not difficult, and there is a lake to walk around which is the highest lake in the world but only very shallow and mostly frozen over.

Just below the summit is a short section of steep rock with some fixed lines in place. At most this is HVS, although the altitude will make you pant! It is not a long section, and there is one bridging move which has some air beneath your feet, but again it is not particularly hard. The final summit is oddly small and rocky, given such a huge and broad mountain.

For the rest of the trip expect desert scrub and arid conditions which are common to the Atacama Desert, the driest desert in the world except for Antarctica. There is almost no rainfall at all, so we need to bring all our own water into the camps from Copiapo. This means the vehicles carry everything for the whole trip. The acclimatisation walks, especially around Laguna Verde, are spectacular experiences, and you often come across petrified remains of wildlife like cougars. It is very hot and dry and dusty in some areas, but there are verdant areas of vegetation lower down. The stark landscape is beautiful, dotted with mulitiple volcanoes as far as the eye can see.

Experience needed for Ojos del Salado

Good teamwork, lots of knowledge about high level mountain trekking and altitude sickness, and an enjoyment of simply being in the mountains are all vital to your general well being. This is not just about physical ability which will require lots of visits to the gym; it is a mountaineering experience which requires fitness of the mind as well as the body. It is important to be efficient and conversant with cold weather survival skills, and all the basics of camping.

Putting a tent up in a strong cold wind is not easy and cooking a dehydrated meal for 3 people in a confined space can be difficult. Good teamwork is vital and it is the key that gets everyone to the top and back down again. Physical fitness in itself will give people confidence to climb the mountain, but the preparation should also involve reading about the mountain, and working on camping skills. Knowing what to put in rucksacks, and where to put stuff, is another vital skill, and issues on Ojos del Salado also include sunburn, cold injuries and tiredness for being high. This sort of knowledgeable reaction to being in these extreme conditions is a necessary part of your experience.

We have two booklets entitled ‘Health on a High Altitude Trek’ and ‘Extreme Climbing’, both of which should give you some excellent knowledge on what is happening to your body up high. This is something that you cannot train for at home and understandably there is sense of apprehension about what will happen. We believe that knowledge is good, so the more you know the less afraid you will be, and the more confidently you can climb the mountain.

Kit List

Mount Ojos del Salado kit list

The basic idea of the kit we will take is to keep you warm, dry, protected from the sun, able to move efficiently on the mountains and able to be comfortable in the evenings and night. There is a detailed list via the menu to the right but the main points to cover are:-

  • BAGS - Large Duffle Bag ~120L (creeid in the 4x4) + Medium Daypack ~45L+ (carried by you on day walks and carries on the mountain)
  • SHELL - Top and bottoms to keep off wind/rain
  • INSULATION - Very warm layered system to keep you warm- body hands & Head
  • BASELAYER - Thin layers to wick away sweat and to strip down to when it gets hot
  • FEET - Crampon compatible boots, more comfortable footwear for evenings/city
  • HARDWARE - Crampons, Walking axe, Trekking poles to allow you to move safely and efficiently
  • SLEEPING - Warm sleeping bag and bed-roll to get a good nights sleep at the camps & refuges
  • EATING/DRINKING - Water bottles & favorite snacks for during the day
  • WASHING & MEDICAL - To allow you to wash and maybe stave off a headache or blister

A variety of clothing will be necessary for your trip. You will need clothing for dining in restaurants, the heat of Mendoza and lower altitudes, and to protect you from the colder temperatures whilst on the mountain. This list is designed to help you choose the right gear for the demands of this trek.The emphasis on equipment necessary for mountain travel follows two simple rules: Lightweight and functional. The items you choose to take should be lightweight, dependable and adaptable to a variety of weather conditions. When making the final decision as to what goes into your pack, remember that it’s a fine science of taking just enough clothes and accessories to do the job, whilst not over burdening yourself with items you probably will not use.

Airlines are very strict on the weight limitations, especially between Santiago - Copiapo and Santiago – Mendoza. Think very carefully about your clothing and equipment and try to stay close to 20kg plus carry on.
