What If Your Trekking Partner Cannot Continue?
What to do when a trekking partner is sick, injured or wants to go home: the NHS descent rule, severe-illness signs, who goes with whom, what happens to the guide and porter costs and how to prepare.

At some point on a long trek, one person in a group is slower, sicker or simply done, and the group has to decide what happens next. The rule for altitude illness is the one the NHS gives: if symptoms are worsening or have not improved after a day, the person descends about 300 to 1,000 m, and if the signs are serious they go down straight away and the rest of the group stops being the priority. For everything else, injury, exhaustion, fear or a family emergency, the answer is a plan you made before the trek, which is why this guide is mostly about preparation.
We cover the situations in order of urgency: a medical emergency, a partner who needs to descend but is not in danger, a partner who needs a rest day or a slower pace, and a partner who wants to go home. For each we say who decides, who goes with whom and what it costs, using the Everest Base Camp and Annapurna Circuit plans as examples. It is general information and not medical advice, and it builds on our guide to what to agree with partners before you book.

Case 1: signs of severe altitude illness
The NHS lists the serious signs: confusion, poor balance or coordination, hallucinations, breathlessness at rest, coughing up frothy or bloody spit, blue or grey lips or skin, and being very drowsy or hard to wake. The CDC adds that HACE can lead to coma within 12 to 24 hours of the onset of ataxia if untreated. If you see these signs in a partner:
- Descend immediately, with a companion and a headlamp if it is dark. Do not wait for morning.
- Give oxygen if the lodge, a clinic or the guide has it, and keep exertion low.
- Call for help. Your guide, the nearest Himalayan Rescue Association post (Pheriche on the Everest route, Manang on the Annapurna Circuit) and your insurer's emergency line.
- Do not leave the person alone. Someone with HACE may not realise how ill they are.
Our guide to HAPE and HACE warning signs has the detail. In this case the rest of the group's plans wait.
Case 2: worsening mild symptoms
Mild altitude sickness usually improves within one to three days with rest, according to the NHS, and the advice is not to go higher until you feel better. If your partner is not improving after a day, or is getting worse, descend about 300 to 1,000 m. On the Everest Base Camp plan, that means going back down the valley from Dingboche (4,410 m) toward Tengboche (3,860 m) or from Lobuche (4,940 m) to Pheriche (4,371 m), where an HRA post gives talks and can assess. On the Annapurna Circuit, from Thorong Phedi (4,540 m) the descent is back to Manang (3,540 m); the person should not try the pass.
The group then has choices:
- Wait at altitude for the partner to recover, if they are improving and the schedule allows. This is why spare days matter; see buffer days.
- The partner descends with the guide or a porter and the rest continue with another guide arrangement, or wait.
- Everyone descends and the trek ends. Sometimes that is the right call.
Which you choose depends on how sick the person is, whether the guide can be split, what the permits and dates allow and what you agreed. Do not make it a vote under pressure. The person who is unwell should not be asked to decide alone.
Case 3: injury or exhaustion
A twisted knee, a blister that has gone bad or plain exhaustion can end a partner's trek without any altitude issue. Our Everest Base Camp route page stresses that the days are long and the return covers the descent in three days, and our Annapurna pages note steep steps and long descents. Poles help knees, and our route plans include rest days, but a partner who is hurting may need to descend by road or flight where one is available. On the Annapurna Circuit, jeep roads reach Dharapani, Chame and Manang, so a partner can leave by vehicle; on the Everest route the flight out of Lukla is the exit, and our Lukla flight guide explains the delays. A partner who must leave from the middle of the trek will need transport arranged by your agency or insurer.
Case 4: a partner who wants to go home
Sometimes the problem is not the body. Fear, cold, homesickness or a bad fit between partners can end a trek. That is a legitimate reason, and the question is how to do it fairly. Our red flags guide lists signs that a partnership is not working. If the partner leaves by choice, the cost agreement you wrote applies.
Who goes with the partner who leaves?
On a guided trek, the guide is shared, and the agency's arrangements matter. Ask in advance:
- Will the guide accompany a partner who leaves, or stay with the group?
- Does the agency provide a second guide or porter?
- What happens to a porter hired for the person who leaves?
- How does the agency charge for the days not used?
Our Everest cost guide notes that if you get sick and descend there is usually no refund on unused days, so check the cancellation and evacuation terms in writing before you pay. If you have no guide, agree that nobody descends alone if they are unwell.
The money
The shared lines do not shrink when someone leaves: the guide and porter are charged per day for the group, so the people who remain pay more per person for the rest of the trek. Our splitting guide and porter costs guide shows the numbers: on Everest Base Camp the guide line per person is about NPR 18,700 to 25,850 for two sharing and NPR 37,400 to 51,700 for one, as of October 2026. If a partner leaves on day 6 of a two-person trek, the remaining person bears the full guide cost from then on. Agree in advance how the difference is shared. A common approach is that the person leaving pays their share of the days used and of any non-refundable commitment, and the others cover the rest. Whatever you decide, write it down.
Insurance may pay for evacuation and sometimes for cancelled arrangements, but only for what the policy covers. Exchange policy numbers before the trek, as our agreement guide recommends.
Preparing for it
- Write the turn-back rule before you book.
- Exchange insurance numbers and emergency contacts.
- Know where help is: the HRA posts and the nearest road or airstrip. See the HRA clinics guide.
- Keep a buffer so that a recovery day is not a disaster.
- Agree in writing how costs are shared if someone leaves.
After the decision
A partner who has to leave often feels guilty, and the group may feel torn. Be kind. Make sure the person who leaves is safe, has transport, knows the plan and can reach someone at home. Keep in touch. If the group continues, adjust the plan honestly: shorten rather than rush, and do not use the partner's departure as a reason to cut acclimatisation. The CDC guidance cited in our altitude pages still holds: above 3,000 m, no more than 500 m of sleeping altitude a night, and an extra night for every 1,000 m.
