Safety Sets the Pace

Safety is Not a Feature. It's the Baseline.

Every trek follows the same approach to altitude: the same guide training, the same safety-equipment baseline, and the same way of deciding when to turn back.

Price does not change how seriously we take your safety. Every LHJ trek, on every tier, follows the same approach to altitude: the same training for guides, the same safety-equipment baseline, and the same decision-making authority on the trail.

This page describes that approach in plain terms: what we can promise today, and what depends on conditions we do not control, like weather, terrain, and aircraft availability in Nepal. Everything below applies to LHJ treks above 3,500 metres.

Safety equipment

What guides carry at altitude.

Guides carry core safety equipment on treks above 3,500 metres. What follows describes what that normally includes; exact kit can vary slightly by route and season.

Pulse oximeter

Guides carry a pulse oximeter on treks above 3,500 metres and use a reading, together with how a trekker looks and feels, to help decide whether to continue, rest, or descend. A reading is one input, not a stand-alone pass or fail test.

Supplemental oxygen

Supplemental oxygen is carried on all LHJ treks above 3,500 metres. It is for the guide to administer if a trekker's condition calls for it. It supports a decision to rest or descend; it is not a way to keep climbing, and a trekker cannot self-administer it to override the guide's judgment.

First aid kit

Guides carry a first aid kit suited to high-altitude trekking, covering common trail injuries and illness. It supports a guide's decisions on the trail; it is not a substitute for professional medical care.

Helicopter evacuation

When a guide and our Kathmandu operations team agree a trekker needs air evacuation, operations works to arrange it as quickly as conditions allow, rather than waiting on a lengthy approval process before acting. Whether a helicopter can fly depends on weather, altitude, and aircraft availability in Nepal at the time, so we cannot guarantee one for every call. Cost is settled with the trekker's insurer afterward, not before a decision to fly.

−20°C down sleeping bags + silk liners

Professionally cleaned, on every tier. Sleep is not an amenity at altitude it is a safety asset.

What we do not carry: a Gamow bag. They are heavy, they are specific to research expeditions, and they are not a substitute for descent. For serious altitude sickness, LHJ's approach puts getting the trekker lower first.

How we watch for altitude sickness

Guides make the call, not a single number.

Above 3,500 metres, guides check in with trekkers regularly and use a pulse oximeter reading as one input among several. What matters most is the overall picture: symptoms, how a trekker looks and behaves, and how they respond as the trek continues. A reading that looks fine does not rule out altitude sickness, and a low reading on its own does not automatically mean a medical emergency; context matters.

Step 1 Stop, rest, go no higher

When early symptoms appear

If a trekker shows early signs of altitude sickness (headache, loss of appetite, nausea, dizziness, or unusual fatigue), the guide stops the group, moves the trekker somewhere sheltered, and reassesses rather than deciding immediately. We do not move to a higher sleeping altitude while any symptoms are present.

Supplemental oxygen, which we carry on every trek above 3,500 metres, may be given if the guide judges it will help the trekker stabilize or rest more comfortably; it is never used as a short boost to clear someone to keep climbing higher the same day.

Only once symptoms have fully resolved at rest, not merely eased, does the guide consider continuing, and then only at a gentler pace with closer check-ins. If symptoms persist or worsen, the guide moves the trekker to a lower altitude. This is the guide's judgment to make, based on how the trekker is doing, not a fixed clock or a fixed number.

Stop, rest, continue only once symptoms resolve

Step 2 Descend immediately

When symptoms are serious

Confusion, loss of coordination, breathlessness at rest, or symptoms worsening quickly are treated as a medical emergency. The guide begins moving the trekker to lower altitude immediately; there is no waiting period. Supplemental oxygen, carried on every trek above 3,500 metres, is used to support stabilization during the descent where the guide judges it will help.

The guide also contacts our Kathmandu operations team to report the situation and arrange further support, which may include ground transport or, where conditions allow, air evacuation.

On a decision like this, the guide's judgment on pace and route takes priority over continuing the itinerary. The trekker is kept informed throughout, but descent is not optional once a guide has made this call.

Descend now, operations alerted

This approach is the same on The Trail, The Journey, and The Transformation. Our guides are trained to recognize and respond to the signs of altitude sickness as part of their standard preparation for high-altitude routes.

Emergency evacuation

Honest about the limits.

Helicopter evacuation depends on weather. The Civil Aviation Authority grounds flights when visibility drops below their minimums and we will not pressure pilots to fly outside those limits. Here is how our response works.

On the trail

Guide assesses + initiates descent

If a guide sees symptoms worsening, or judges a trekker is not safe to continue, they pause the trek and start moving that trekker toward lower altitude. This decision is the guide's to make in the moment; it does not wait on a fixed number being crossed.

As soon as practical

Contact with our Kathmandu team

The guide contacts our Kathmandu operations team to report the situation and the plan, where terrain and signal allow. Operations works to clear the way for the next step, including air evacuation if needed and conditions allow, without waiting on a drawn-out approval process. Cost is worked out with the trekker's insurer afterward, not before we act.

Weather-dependent

Heli pickup or assisted descent

If flying conditions allow, a helicopter pickup is arranged from the nearest safe landing area. If not, the trekker continues descending on foot or by horse, with the guide, toward a lower point where flying may become possible, or all the way down if needed. We do not promise a pickup time; weather in the Himalaya can close a flying window for hours or days.

What we will not promise

Helicopter evacuation above 5,000m is unreliable. Thin air reduces rotor efficiency and weather windows are narrow. Every LHJ itinerary is designed so that a ground descent on foot, or by horse from the nearest lodge is the primary option at any altitude, with helicopter as backup.
Lukla flight delays and cancellations are common. Tenzing-Hillary Airport at Lukla operates under strict visual-flight rules in narrow mountain terrain, and flights are frequently delayed or cancelled when cloud or wind closes the valley. Build at least two buffer days into your international travel plans. We do not pressure airlines or put a group on a flight in marginal weather.
Insurance must cover helicopter evacuation in Nepal. This is verified during the pre-trek documentation process. If your insurance does not cover it, we will tell you and the trek does not start until the coverage is in place.

Guide credentials

Every LHJ guide, every trek, every tier.

These are floor requirements, not aspirations. Each guide also completes LHJ's internal training on recognizing altitude sickness, pulse oximeter use, and emergency communication.
