On Aconcagua, mules and high-altitude porters work on different parts of the route. Mules carry the agreed loads along the approach as far as Plaza de Mulas and back. Above base camp, loads are carried by people. Misunderstanding that boundary is a common cause of excess weight and unexpected costs.
Two systems for moving loads
What the 17-day programme includes
The published package covers the carriage of equipment and food by mule from the Puente del Inca and Los Puquios area to Plaza de Mulas and back. Maximum personal baggage is stated as 30 kg. That is the limit on the approach, not a promise to carry 30 kg up to Nido de Condores or Cólera.
High-altitude porters appear under additional costs. If the service is not booked, you should expect to carry your own personal equipment and your assigned share of the group load between the high camps.
How loads are distributed
| Section | The usual arrangement | What to check |
|---|---|---|
| Before the approach starts | Splitting the duffel bag and the daypack | Weight and labelling |
| Horcones to Confluencia | The participant’s daypack | Water, clothing and personal items |
| Confluencia to Plaza de Mulas | Mules plus the daypack | When you next get at the duffel |
| Above Plaza de Mulas | The participant or a porter | Weight and the handover point |
| The descent | Carries back down and mules | What is handed over, and when |
What a high-altitude porter does
The service may mean a single load carry, moving part of your personal kit, moving a camp, or several stages. These are not the same thing. The order records the weight, the direction, the handover point, the date, the number of stages and what happens if the programme changes.
- Plaza de Mulas to Plaza Canada.
- Plaza Canada to Nido de Condores.
- Nido de Condores to Cólera.
- Carries back down after the attempt.
- A single carry made before the team sets off.
The list above shows possible points for discussion, not an included package. The actual service is confirmed separately.
Planning your own load
Why a porter does not solve a preparation problem
Reducing weight saves energy, but it does not provide acclimatisation and it is no substitute for endurance. You still carry a daypack with clothing, water, food and critical equipment, still live in the high camps and still face the summit day.
How to pack the duffel
- Use a strong duffel that closes properly.
- Protect the sleeping bag and clothing with dry bags inside.
- Label it with your name and the operator’s contact details.
- Do not pack documents, medication or anything you need before the duffel is returned.
- Check which items are prohibited or count as fragile.
- Weigh the duffel at home, leaving some margin.
Questions to ask before paying
- What exactly is the personal load limit?
- Where and when is the duffel handed over to the mules?
- When do you get your things back?
- Is the return leg included?
- Which high-altitude carries does this particular group need?
- How does the quotation change if a day is moved?
- Who is responsible for the group equipment?
The current terms are on the page of the 17-day programme. For an independent team, compare the packages with up to 7 days of full board and up to 4 days of full board, and read up on the full logistics and on personal equipment.
How to work out the weight you need moved
Start with a complete kit list, then separate the items for the approach, for base camp and for the high section. Next, allocate the group load, and only then decide whether you need a porter. Buying the service against an abstract number of kilograms, with no route for the carries, is inefficient.
| Category | Example | Who is responsible |
|---|---|---|
| Critical personal items | Clothing, water, medication | Always the participant |
| Personal high-altitude kit | Sleeping bag, mat, boots | The participant, or a booked carry |
| Group equipment | Tent, food, fuel | According to the team’s allocation |
| Base camp duffel | Spare kit and toiletries | Mules, under the package |
| Rubbish and empty gas | After use | According to the carry-out plan |
When a porter is particularly useful
An extra carry can make sense for a private group, for someone with limited experience of a heavy rucksack at altitude, or for a team that wants to save its strength for the summit. But the decision follows an honest assessment of fitness, and it should not be used to conceal a medical limitation that is incompatible with the route.
What must never go into a carry
- Documents and insurance.
- Personal medication.
- Insulation you need on the current stage.
- Water and food for the day.
- A head torch, if darkness is possible.
- Anything you need in order to wait safely for your baggage.
If the programme changes
Weather or the state of the team can shift a carry. You need to know in advance whether the service moves with it, whether the price changes and where your load is. The verbal formula „there’ll be a porter“ is not enough for high-altitude logistics.
A full budget including porters is set out in the article on cost, and the difference between logistics and guiding in the comparison of packages.
Frequently asked questions about carries
Can I book a porter once I am at base camp?
Local capacity is sometimes available, but you cannot build a plan on it. Confirm the number of carries, the weight and the stages in advance. In season, there may be no porter free on the date you need.
Does the daypack count towards the mule limit?
The limit applies to the personal baggage you hand over under the terms of the programme. The daypack stays with you and has to contain everything you need until you next reach your duffel.
Can I send my whole high-altitude kit up in advance?
Only under an agreed arrangement. Do not hand over anything you may need before you meet your load again. Allow separately for a change in the weather and for a camp being moved.
Does the porter walk with me?
A one-off load carry and personal accompaniment are different products. State explicitly what you are buying, and do not assume company on the route from the word „porter“.
The specification for a high-altitude carry
The service is recorded as one line per stage: date, direction, camp of departure and arrival, weight, number of porters, handover point and what happens if the schedule changes. „A porter for the expedition“ is not an adequate description.
| Parameter | What to record |
|---|---|
| Load | Personal, group or both |
| Weight | The limit in kilograms for that particular stage |
| Direction | Up, down or both ways |
| Handover | Place, time, labelling and the person responsible |
| Changes | Moving the date, cancellation and any extra cost |
For an agency, a club or your own guide, carries are included in the Aconcagua B2B specification. For a private group the service is quoted according to the make-up of the team, their fitness and how the group equipment is shared out.
Read the price together with the weight and the number of stages. A cheaper line may cover only one carry, while a more expensive one may include moving a camp and bringing everything back down. A porter who has not been confirmed does not count in your personal load plan.
Three different weights in one expedition
The airline baggage allowance, the load for the mules and the high-altitude rucksack are three separate figures. The fact that an airline accepted your bag does not mean all of that weight will fit the mule service. And the 30 kg limit to Plaza de Mulas says nothing about carrying the same weight higher up.
| Weight | Where it applies | Who confirms it |
|---|---|---|
| Airline baggage | The flight to Argentina | The airline |
| Personal load on mules | The approach to base camp and back | The programme terms and the local operator |
| High-altitude carry | The sections above Plaza de Mulas | A separate porter specification |
| Daypack | Every walking day | The route plan and the guide |
Handing the duffel over to the mules
Before handover, weigh the duffel, label it and photograph it. Know where and when you will next have access to it. Inside, protect your kit from dust, damp and abrasion; fragile items should not be assumed to get careful, hotel-style handling.
Pack your daypack before the handover. If your medication, water, insulation or documents have gone off with the duffel, there may be no way of putting that right on the approach.
The chain of responsibility for loads
- The participant hands over a closed, labelled duffel.
- The person responsible records the weight and the number of items.
- The load travels the agreed section.
- At the collection point the participant checks everything is there.
- Damage or anything missing is reported immediately.
The specific rules on claims and liability are set out in the terms of the service. This article promises no compensation in the absence of a contract.
A single carry and moving a camp
With a single carry, the porter can deliver the agreed load in advance and you meet it later. When a camp is moved, the service is tied to the actual movement of the team and its kit. These are different tasks in terms of timing and risk.
Confirm the return direction separately. A carry upwards does not automatically include the descent after the summit unless the order says so.
Group equipment
Tents, food and fuel are shared out by the team. Before pricing a personal porter, you need to know your share. Otherwise you may book a carry for your personal items only and fail to allow for your assigned part of the group kit.
If the group splits, the group load is recalculated. The tent system must not go off with a subgroup that is following a different plan.
What stays in the daypack
- Clothing and insulation for the current stage
- Water and food
- Personal medication and documents
- Head torch and sun protection
- Technical items needed before you meet your load
- A minimum reserve in case of delay
The guide decides the exact contents. A porter reduces the weight, but you still have to be able to finish the stage safely without immediate access to your duffel.
If the porter goes faster, or separately
The load may arrive before the team, but that says nothing about personal accompaniment. Agree the handover point, the labelling, the person responsible and where the load is stored.
Do not hand over anything you need on the way simply because a porter says they will be walking alongside you. The service is judged by the written route your load takes.
A change in the weather or in the day of the carry
If the programme shifts, the porter may already be committed to another job. Before paying, establish whether the date can be changed, what notice is needed, any surcharge and the cancellation terms. The tour’s reserve days do not guarantee that the service is extended free of charge.
If a load has gone to a camp the team is no longer using, the leader coordinates its return. Do not go after it yourself.
How to order a carry without ambiguity
| Field | Example content |
|---|---|
| Stage | Camp of departure and camp of arrival |
| Date | The planned date and the permissible shift |
| Weight | The limit per porter |
| Load | Personal, group or mixed |
| Direction | Up, down or both |
| Handover | Time, place and the people responsible |
| Changes | Cancellation, rescheduling and any extra cost |
Checks after each stage
Check the sleeping bag, mat, clothing, technical kit and the condition of the packaging before the porter leaves. Report anything missing straight away, not while packing the next morning.
After the descent, count all the items again before handing them to the mules. The high-altitude duffel and your base camp kit are then recombined according to the transport arrangements.
Packing, damage and fragile items
The duffel has to close with no straps hanging loose, and the contents have to withstand abrasion and pressure from the loads next to it. Isolate crampons, poles and other sharp items from your sleeping bag and clothing. Put liquids in additional waterproof packaging.
A camera, a laptop or other fragile electronics are not ordinary safe cargo for a mule without a separate agreement. If such an item is accepted, put the terms of liability in writing.
What the cost of a porter depends on
- The weight of the load
- The camps of departure and arrival
- Whether the direction is up or down
- One stage or several carries
- The planned date and how urgent it is
- Whether waiting or accompaniment is required
- Changes to the schedule after booking
So compare like-for-like specifications rather than the price attached to the word „porter“. One line may cover a single carry, another moving a camp and bringing it back down.
The standard, private and B2B arrangements
In a standard group, the leader decides how the group load is shared out. On a private programme, carries are tailored to the team and the level of service wanted. In a B2B package the client receives a stage-by-stage specification for their own team.
No format removes the daypack or your own readiness. Porter services should never be sold as a guarantee of the summit or as a way of making the route medically easier.
Mistakes that come to light too late
| Mistake | When it shows up | How to prevent it |
|---|---|---|
| The group load was not allowed for | On the move above base camp | Allocate it before pricing anything |
| Only the ascent was booked | After the summit | Confirm the descent separately |
| A critical item went up early | During the day’s walking | Check the daypack before the handover |
| No agreement on shifting the date | When the weather turns | Put the terms for changes in writing |
Paperwork for a carry order
The confirmation should carry the client’s name, the make-up of the group, the route, the stages, the dates, the weight, the number of porters, the price and the payment and cancellation terms. Keep the coordinator’s contact details offline.
Record separately what happens if one participant descends early, if the whole group is delayed, and if a particular stage cannot be carried out. A general force majeure clause does not tell you where your load is.
After paying, you should receive not only a receipt but a matching route specification. If the weight or the number of stages has changed, the quotation is updated before you hand anything over.
Copies of the confirmations should be available offline to both the participant and the leader. A verbal arrangement with someone at base camp is no substitute for a confirmed order when your entire personal load plan depends on it.
The labelling in the paperwork matches the labelling on the duffel.
The final way to work it out
First establish the full personal and group weight, then the daypack you must carry, and only then what is left to be carried on each section. You cannot simply multiply the number of stages by one abstract price: the directions and the conditions differ.
The calculation is complete when you know what you are carrying yourself each day and where you collect the rest of your load.
