Lhasa altitude facts
Lhasa sits on the Tibetan Plateau in the valley of the Kyichu River. It is one of the lowest points in Tibet — yet still nearly four times the height of Australia's highest mountain. The reduced oxygen levels affect almost every visitor in some way.

AMS symptoms
acclimatisation time
A large cross-sectional study of 2,385 tourists arriving in Lhasa found that over a third developed acute mountain sickness (AMS) within the first three days — and nearly half of those reported symptoms within the first 12 hours of arrival.
Altitude levels across Tibet
Lhasa is your likely entry point — but many Tibet itineraries venture to significantly higher elevations. Each step up increases your risk substantially.
| Destination | Altitude | AMS Risk | Notes |
|---|---|---|---|
| Nyingchi | 3,000m · 9,842ft | Low–Moderate | Popular entry point, lower elevation |
| Lhasa | 3,658m · 11,975ft | Moderate | 36.7% of tourists affected |
| Shigatse | 3,836m · 12,585ft | Moderate–High | 2nd largest city in Tibet |
| Gyantse | 4,040m · 13,255ft | High | Acclimatise in Lhasa first |
| Namtso Lake | 4,718m · 15,479ft | High | Day trips only recommended |
| EBC (Tibet side) | 5,200m · 17,060ft | Very High | Requires careful staged ascent |
Altitude sickness symptoms
Symptoms in Lhasa typically begin within 6–12 hours of arrival. Understanding the progression from mild to severe can be the difference between a safe trip and a medical emergency.
- Headache (especially on waking)
- Fatigue and weakness
- Dizziness or light-headedness
- Nausea or loss of appetite
- Poor sleep
- Persistent, worsening headache
- Vomiting
- Severe fatigue
- Reduced urine output
- Shortness of breath at rest
- Confusion or disorientation
- Loss of coordination
- Persistent dry cough
- Chest tightness or gurgling
- Impaired consciousness
If you experience severe symptoms, descend immediately and seek medical attention. Do not sleep at the same altitude with worsening symptoms.
Recommended acclimatisation for Lhasa
Most travellers fly directly into Lhasa. The sudden altitude gain is the single biggest risk factor. Here is the ideal first few days.
Check into your hotel and rest for the remainder of the day. No sightseeing. Drink 3–4 litres of water. Avoid alcohol and sleeping pills. Eat lightly.
If you feel well, take short walks around your neighbourhood. Avoid climbing stairs quickly or exerting yourself. Visit the Barkhor area on foot — keep it slow. Note any headache or nausea.
Most visitors feel significantly better by day 3. The Potala Palace stairs are a genuine test — take them slowly and rest often. If symptoms persist, do not push on to higher elevations.
Having acclimatised in Lhasa, you can consider Shigatse or Gyantse. Never ascend to a higher sleeping altitude while still experiencing AMS symptoms.
Check your personal risk level
Your altitude sickness risk depends on more than just the altitude — age, fitness, prior experience, how quickly you ascend, and existing health conditions all play a role. Use our calculator to get a personalised assessment.

6 ways to reduce your risk in Lhasa
- 1 Arrive via a mid-altitude stopover. If possible, spend 1–2 nights in Chengdu (506m) or Xining (2,275m) before flying to Lhasa. This gives your body a chance to begin adjusting.
- 2 Drink water, skip the drinks. Dehydration accelerates AMS. Aim for 3–4 litres of water daily from the moment you land. Avoid alcohol for at least the first 48 hours.
- 3 Consider Diamox (acetazolamide). This prescription medication can halve your risk of AMS. Start 1–2 days before arrival. Consult your doctor — it's not suitable for everyone, and requires a prescription.
- 4 Rest on day one, no exceptions. Your body needs 24–48 hours to begin producing more red blood cells. Sightseeing can wait. Every hour of rest on day one reduces your risk meaningfully.
- 5 Eat lightly and avoid sleeping pills. A heavy meal stresses your system. Sleeping pills can suppress breathing during sleep, worsening oxygen levels — exactly what you don't need at altitude.
- 6 Know when to descend. If symptoms worsen after 24 hours, or if you develop confusion, loss of coordination, or chest tightness — descend immediately. Altitude kills slowly and then quickly.
