The logistics of Ojos del Salado are built around Copiapó, 4×4 vehicles, stocks of water and fuel, high-altitude camps and the state of the roads in the Atacama desert. A vehicle makes it easier to move people and equipment, but it does not guarantee passage and it does not replace acclimatisation. The decision about how far up the drop-off can go is taken on the conditions of the day.
| Stage | Altitude on the programme | The logistical task |
|---|---|---|
| Copiapó | town | Hotel, paperwork, food, fuel and a check of everyone’s kit |
| Laguna Santa Rosa | 3700 m | First night at altitude and the start of adaptation |
| Laguna Verde | 4250 m | The camp for the acclimatisation walks that follow |
| San Francisco | 6018 m | An acclimatisation summit in its own right |
| Atacama | about 5300 m | The camp below the upper part of the route |
| Tejos | about 5800 m | Refuge or tented camp, depending on availability |
| Ojos del Salado | 6893 m | The summit attempt and a safe return |
Copiapó, the starting point
The standard Mountain Guide programme starts in Copiapó. The team spends the night in a hotel here and checks personal and group equipment, food, water, documents and transport. Once you drive out into the desert, the chance of quickly replacing high-altitude boots, crampons, a sleeping bag or a vehicle part drops sharply.
Before arrival, flights, baggage, the pick-up, the hotel and the departure time are all confirmed. If people are arriving on different flights, each transfer is arranged separately. Delayed expedition baggage needs a plan agreed in advance.
Why a 4×4 is necessary
The high-altitude roads of the Atacama vary in condition. What is needed is a suitable off-road vehicle, an experienced driver, navigation, a fuel reserve, water, a repair kit and a means of communication beyond the mobile network. An ordinary car is not an equivalent substitute.
Whether a section is passable depends on snow, wind, the surface and the state of that particular stretch. The published drop-off point describes the plan, not an unconditional guarantee. If the road is closed, the guide and the driver change the stopping place or the schedule. You have to be ready either to walk further or to give up going higher.
Nor does a vehicle speed up physiological adaptation. Gaining height quickly by car can increase the strain, which is why the overnight stops and the acclimatisation walks stay in the plan even when it is technically possible to drive higher.
The sequence of camps
On the 15-day programme the first night at altitude is at Laguna Santa Rosa, at 3700 m. The group then moves to Laguna Verde at 4250 m and does its acclimatisation walks. Before Ojos there is an ascent of San Francisco to 6018 m.
After recovering, the team moves to Atacama at around 5300 m and Tejos at around 5800 m. Tejos is used either as a refuge or as a place to camp, depending on what is actually available. Heating, showers, electricity, a phone signal and a bed of your own are not to be counted as included without explicit confirmation.
What each of those points is for is set out in more detail in our article on the camps of Ojos del Salado.
The short programme and pre-acclimatisation
The eight-day Ojos takes you almost straight up to the Atacama camp. It is only accepted with recent acclimatisation at no less than 5000 m. That can be a continuation of Aconcagua, Bolivia, Ecuador, Elbrus or another agreed programme, provided the altitude profile and the recovery are intact.
Eight days is not an option if you are flying in from sea level. Removing Santa Rosa, Laguna Verde and San Francisco does not make the route more efficient – it moves all the preparatory altitude outside the Chilean programme.
Water, food and fuel
On the remote part of the route you cannot count on a shop, a restaurant or a permanent source of drinking water. Before departure the team works out water for drinking and cooking, fuel for the vehicles and the kitchen, a margin for delays and the food for everyone.
Dietary restrictions and allergies must be declared in advance. The operator confirms what can actually be substituted; a general note that “vegetarian meals are possible” does not describe what you will eat at altitude. Bring your own tried-and-tested food for summit day only once it has been agreed with the programme.
Permits and registration
Access rules, paperwork and the regulations of the protected areas are checked before every departure. Help with obtaining permits is part of the 15-day programme; the permit itself is paid for separately. No figure is quoted in this article without a confirmed current tariff.
Help with the paperwork is not the same as paying a state or local fee. Your documents, who submits the data, the cost, the confirmation deadline and the rules for changes are all recorded separately in the calculation.
Communications and the emergency plan
Mobile coverage and internet at the camps are not guaranteed. The team uses an agreed means of communication, conserves battery and keeps spare batteries and offline copies of documents. Check-in times and a contact who knows the route are set before departure.
Having a 4×4 does not mean immediate evacuation: the road may be closed, the vehicle may be somewhere else, and the person’s condition may call for something different. The contract distinguishes between calling for help, arranging transport and paying the costs. Your insurance must cover mountaineering, an altitude of at least 6900 m, rescue and evacuation.
The environment and the protected areas
The high-altitude lagoons and salt flats are fragile ecosystems. Vehicles stay on permitted roads, the team does not disturb wildlife or contaminate the water, and everything is carried out. Instructions from park staff take priority over any tourist plan.

Standard and B2B logistics
The standard expedition covers the route, the guiding and the services listed. Ojos B2B logistics is intended for agencies, clubs and guides who need a receiving ground operation for a product of their own.
For a B2B quotation you supply the dates, the size and nationalities of the group, the route, whether you bring your own leader, the vehicles, camps, meals, group equipment, permits, local guides, contingency and the division of responsibility. Mountain Guide confirms each element separately.
The logistical chain from Copiapó to Tejos
The remoteness of Ojos makes the unbroken chain matter more than any single vehicle. People, personal baggage, water, fuel, food, tents and the means of communication all have to arrive at the same place at the same time. If one element falls behind, the altitude plan can become impossible even in good weather.
| Stage | What gets confirmed | The main variable |
|---|---|---|
| Copiapó | The group, documents, equipment, loading and contacts | Delayed baggage or a critical missing item |
| Laguna Santa Rosa | The first night at altitude, water, food and the camping kit | How people first react at 3700 m |
| Laguna Verde | The camp and readiness for the acclimatisation walks | Wind, cold and recovery |
| San Francisco | Transport to the start and back, and the check-in times | Pace and condition after going to 6018 m |
| Atacama | How far the vehicles actually get, the overnight stop and the supplies | Snow and whether the road is passable |
| Tejos | Refuge or tents, and the plan for the main climb | Whether the road and the accommodation are available |
This table describes the tasks; it does not guarantee an unchanging drop-off point. The actual approach is confirmed on the ground. Good logistics preserve the purpose of a stage even when the vehicles stop lower than expected or the refuge is unavailable.
What a 4×4 specification has to contain
The request states the number of participants and guides, the volume of baggage, the group load, which sections are being driven and where the meeting points are expected to be. Capacity is assessed together with the water and fuel, not by the number of seats alone. Where several vehicles are involved, critical supplies are distributed between them in advance.
- A vehicle and a driver for each section
- The number of seats with the full load on board
- How baggage is labelled and loaded
- Water and fuel reserves, and who is responsible for monitoring them
- Where and when communications will be re-established
- What happens in the event of a breakdown, a delay or a closed road
- How additional journeys are confirmed
A promise that “the vehicle is included” cannot be compared with another offer without those points. It is especially important to state whether the transport applies to the participants, to the group load, or to both.
Where logistics end and leadership begins
The driver is responsible for completing the agreed transport section safely. The mountain leader is responsible for the pace, the acclimatisation, splitting the group and the decision about carrying on. The two roles can be coordinated, but one does not arise automatically from the other.
A B2B order states explicitly whether the client is bringing their own leader. If they are, the specification names the services the local operator provides and how contact is maintained. If not, what is needed is a guided programme or a separate quotation for the guiding, not simply the hire of vehicles and camps.
The plan when the road changes
What is settled before departure is not an exact weather forecast but the rules for reacting. A lower drop-off means more walking and more time, may change where you sleep and may call for the main attempt to be reconsidered. The decision is taken by the leader, on the actual conditions and the state of the team.
Contingency days allow the order to be changed, but they do not guarantee a second attempt at the summit. If a change in the road has used up the team’s reserves of energy, fuel or time, going down may be the safe decision. Additional services are agreed against units of cost that have been set out in advance.
Handing the order to the local operator
The final schedule sets out the route, the group, the contacts, the transport, the camps, the nights, the meals, the water, the fuel, the baggage and the exclusions. It carries a date and a version number. Any change after confirmation is flagged separately and accepted by both sides.
Where Mountain Guide sells the programme to the client and a local partner delivers part of the services, the public promise and the operational order have to match. That is what stops a situation where the client expects to be guided and the contractor has only received a request for a vehicle.
What information is needed for an accurate quotation
“We need a jeep for Ojos” is not enough to price a safe service. The operator needs the group, the dates, the route, the roles, the volume of equipment and the camps required. For B2B, state separately that you are bringing your own leader and which services they will not be covering.
| Information | What to state | What it affects |
|---|---|---|
| The group | Participants, guides, nationalities and languages | Transport, paperwork and communications |
| The calendar | Arrival in Copiapó, the start of the route and the return | Vehicles, drivers, camps and contingency |
| The route | Overnight stops and acclimatisation walks | Supplies, how far the vehicles work and the meeting points |
| Baggage | Personal and group volume, vehicle by vehicle | Capacity and the number of journeys |
| Accommodation | Tents, the refuge if available, and the fallback | The camping kit and the plan if the road is closed |
| Meals | Days, places, restrictions and how food is issued | Purchasing, water, fuel and the kitchen |
| Leadership | Who runs the group and decides on a turnaround | Whether a separate Mountain Guide leader is required |
Once that information is in, a specification is drawn up with inclusions and exclusions. If the client later changes the group or the overnight stops, the price and the transport are recalculated. An old quotation cannot simply be applied to a new group.
How to check the water and fuel reserves
This article cannot set a universal quantity: it depends on the people, the days, the kitchen, the vehicles and the fallback plan. The operational plan names who is responsible for the calculation, the loading and the daily monitoring. Consumption is recorded so that the team can see what is left before moving on to the next remote point.
Water for people, for cooking and for practical needs must not sit as one vague line. Vehicle fuel and kitchen fuel are also kept separate. If part of the supply is in another vehicle or at another camp, the leader knows when it will become available.
The reserve is not spent as ordinary supply in the first few days. It is tied to a specific scenario: a delay on the road, an extra night or a changed return. The decision to use it belongs to the person designated for that, not to whoever happens to be in camp.
The final check before leaving Copiapó
- Every participant, guide and driver appears on the current list
- Documents and permits have been checked against the current route
- Baggage is labelled and distributed between the vehicles
- Water, fuel, food and the group kit have been checked against the schedule
- Check-in points and times have been set
- Both the planned and the alternative overnight stops are confirmed
- The leader has offline copies of the contacts and the insurance details
If a critical item is not settled, driving out does not settle it. The remoteness of the route makes stopping early in Copiapó cheaper and safer than improvising late at the upper camp.
After the check the leader briefly explains to the group how the vehicles will travel, how to get at personal belongings and what to do if the group is split. Everyone knows which vehicle holds their warm clothing and the essential kit for the first night out. Documents, regular medication and communications are not put into inaccessible group baggage. Any change in the loading goes straight into the schedule and is passed on to the drivers. The check is repeated after every significant redistribution of baggage between vehicles and camps. The result of the check is given to the whole group in writing before the convoy moves on.
What to check before you pay
- Every point on the route and every overnight stop, with its altitude.
- The number and type of 4×4 vehicles and the days they work.
- The drivers, the fuel and what happens if the road closes.
- The tents and how far Tejos is actually available.
- The food, the water, the kitchen fuel and any special diets.
- The permits, the fees and who submits the paperwork.
- The ratio of guides to participants on the climb.
- Communications, insurance and the evacuation procedure.
- The two contingency days, and the costs if the schedule changes.
- What remains the client’s own responsibility.
