How to Acclimatize in Tibet: A Day-by-Day Plan

Altitude is the single biggest physical challenge of a Tibet trip, and the good news is that it's largely manageable with a sensible plan. Most travellers acclimatize well by doing a few simple things consistently: arriving slowly, resting at first, ascending gradually, and hydrating hard. This guide turns that into a concrete, day-by-day plan you can follow.

This article complements our broader altitude sickness guide; here the focus is on the schedule.

The Core Principles

Everything below rests on a handful of rules that mountaineers live by:

• Rest first. Your main job in the first 48 hours at altitude is to do very little.
• Ascend gradually. As a rough guide, once you're going higher, aim to raise your sleeping altitude by no more than about 300–400 metres per day.
• "Climb high, sleep low." Going higher during the day is fine, as long as you come back down to sleep lower.
• Hydrate aggressively. Acclimatization causes fluid loss; aim for around 4 litres of water (or more) a day.
• Skip alcohol and go easy on heavy exertion in the early days.
• Eat well. A high-calorie diet helps your body cope.

Keep these in mind and the day-by-day plan below mostly takes care of itself.

Day 1: Arrival in Lhasa (≈3,650 m)

Lhasa sits at about 3,650 metres, and for most visitors this is the altitude where the body first has to adapt. Today is about doing almost nothing.

• No heavy activity. No hiking, no gym, no fast walking, no lugging bags up stairs.
• Check in and settle. A short, slow stroll near your hotel is the most you should attempt.
• Start drinking water immediately and keep it up.
• Eat a proper meal, even if your appetite is down.
• Expect mild symptoms. A light headache, slight breathlessness, or broken sleep on the first night is common and usually settles.

Resist the temptation to "push through" with sightseeing on arrival day. Giving your heart and lungs time now pays off for the rest of the trip.

Day 2: Gentle Lhasa Sightseeing

With one night behind you, you can begin gentle, low-exertion sightseeing, this is exactly why a Lhasa-first itinerary works.

• Visit central, low-effort sights, the Jokhang Temple and a slow walk on the Barkhor are ideal.
• Keep climbing to a minimum. If you're tackling the Potala's many stairs today, go slowly with frequent pauses.
• Continue heavy hydration and a good diet.
• Listen to your body and report anything worsening to your guide.

Day 3: Second Full Day Before Going Higher

We recommend at least two full days in Lhasa before ascending to higher destinations. Use this day to consolidate your adjustment.

• Add slightly more activity, the Drepung or Sera monasteries, while staying within comfortable limits.
• By the end of today, most travellers feel markedly better than on arrival.
• This is your platform: only push higher once Lhasa feels manageable.

Days 4+: Ascending Gradually

Once you leave Lhasa for higher places, apply the gradual-ascent and climb-high-sleep-low rules. A well-designed route does this for you, stepping up through intermediate elevations rather than jumping straight to the highest point.

Day	Example stop	Approx. sleeping altitude	Note
1–3	Lhasa	~3,650 m	Rest and acclimatize
4	Gyantse / Shigatse	~3,900–4,000 m	Modest step up
5	Tingri area	~4,300 m	Higher staging point
6	Everest Base Camp area	~5,150–5,200 m	Highest night; expect shallow sleep

This is illustrative, your exact route varies, but it shows the principle: build up in stages. A jump like Lhasa straight to Everest Base Camp without intermediate nights is exactly what to avoid. Our Everest Base Camp Tour (8 Days) is structured around this staged ascent.

Hydration and Diet, Specifics

• Water: aim for roughly 4 litres a day; carry a refillable bottle. Oral rehydration salts, juice, soup, and even traditional remedies like garlic-flavoured broth are all used by travellers to keep fluids and salts up.
• Food: favour warm, high-calorie meals; don't skip food just because appetite dips.
• Avoid alcohol, especially in the first few days, it worsens dehydration and masks how you really feel.

Medication: Talk to Your Doctor

Some travellers take acetazolamide (Diamox) to speed acclimatization. Important caveats:

• It can aid acclimatization but does not mask symptoms, you still need to monitor how you feel.
• It is a prescription medication: discuss it with your own doctor before the trip, including dosage and side effects.
• It's an aid, not a substitute for sensible pacing and hydration.

Warning Signs: When to Act

Mild symptoms (light headache, mild nausea, breathlessness on exertion, poor first-night sleep) are common and usually improve with rest and fluids. But certain signs mean you must stop ascending and tell your guide immediately:

• A severe or worsening headache that doesn't respond to rest or painkillers
• Persistent vomiting
• Breathlessness at rest
• Confusion, severe dizziness, loss of coordination, or unusual drowsiness

These can signal serious altitude illness. The single most reliable treatment is to descend. Don't tough it out, and don't let pride keep you climbing. Your guide is experienced in this and is your first point of contact.

A Realistic Reassurance

The large majority of travellers, often cited as over 90%, adjust well by following these basics. You don't need to be an athlete; you need to be patient. Rest on arrival, give Lhasa two full days, go up in steps, drink far more water than feels natural, and speak up early if something feels wrong.

Do that, and the altitude becomes a backdrop to an unforgettable trip rather than the thing that derails it. Want a route built around safe pacing? Get in touch, or start with our first-time Tibet guide.
