Altitude Sickness on Xinjiang Drives (Pamir & Tianshan)

The first time I slept in Tashkurgan, at about 3,100 m, I woke at 3 a.m. with a hammering headache and a racing heart. I had driven up from Kashgar in one push, eaten a big dinner, and gone straight to bed — everything you are not supposed to do. The next trip I did it differently, and I slept fine. Altitude on the Xinjiang roof is real, but it is manageable if you respect it. This is the guide I wish I had read before that first restless night.

Where the altitude actually is

Most of Xinjiang is low and flat — Urumqi sits near 800 m, Turpan is below sea level, and the Ili grasslands are gentle. Altitude only becomes a factor on two fronts:

  • The Pamir Plateau. Tashkurgan town is around 3,100 m. Karakul Lake rests near 3,600 m. The road to the Khunjerab Pass climbs to roughly 4,700 m at the border marker. This is the serious altitude zone, on the Karakoram Highway self-drive corridor.
  • The high Tianshan passes. The Duku Highway summit, near the Tianshan “Devil’s Pass” (Tianger) area, reaches about 3,400 m. You cross it quickly rather than sleeping there, but the brief exposure can still affect sensitive travelers.

For context, acute mountain sickness (AMS) commonly begins around 2,500 m and gets more likely above 3,500 m. The Pamir is squarely in that band.

Symptoms to know

Mild AMS feels like a hangover: headache, tiredness, loss of appetite, mild nausea, trouble sleeping. That is common and usually tolerable. The danger signs — and reasons to descend immediately — are:

  • A severe headache that does not respond to rest or water
  • vomiting, confusion, or loss of coordination (ataxia)
  • breathlessness at rest, or a tight chest
  • bluish lips, or a cough with frothy sputum

These point to high-altitude pulmonary or cerebral edema, which are medical emergencies. They are rare on a normal Pamir visit, but knowing the line between “mild and annoying” and “descend now” is the single most important thing in this article.

The rhythm that works: sleep low, climb high

Your body adapts to altitude by making more red blood cells, but that takes days. What you can control is the rate of ascent. The principle I follow is “climb high, sleep low.”

  • Spend a night in Kashgar (~1,300 m) first. It is the natural launch pad and a gentle starter.
  • Break the climb. On the Kashgar to Pamir Karakul drive, pause at Baisha Lake (around 3,200 m) and Karakul Lake (3,600 m) during the day, but if you feel off, do not linger — push on or drop back down.
  • Sleep in Tashkurgan (3,100 m), not at Karakul (3,600 m), unless you are well acclimatized. Tashkurgan is the lowest comfortable bed on the plateau and a smart base.
  • For Khunjerab, go up and come back the same day. The Khunjerab Pass drive tops out near 4,700 m, but you do not sleep there; you climb, enjoy the border marker, and descend to Tashkurgan to recover.

Daily habits that prevent trouble

Small things add up:

  • Hydrate hard. The Pamir air is bone dry; you lose water fast. I drink 2–3 liters a day there and still feel thirsty.
  • Eat light, eat carbs. A heavy meat feast the first night is a mistake I have made. Plain rice, noodles, and soup sit better at altitude.
  • Skip the alcohol. A “welcome” glass of whisky at 3,100 m hit me far harder than at home. The first two nights, I avoid it.
  • Move slowly. Walk like you are late for nothing. Rushing up stairs in Tashkurgan will remind you where you are.
  • Sleep with the window cracked for fresh air if the room feels stuffy, and consider a slightly raised pillow for the mild breathlessness.

Medication: ask a doctor, not the internet

Some travelers use acetazolamide (Diamox) to speed acclimatization, and others carry dexamethasone for emergencies. I am not a doctor, and I will not prescribe. If you have heart or lung conditions, are pregnant, or worry about altitude, talk to a travel-medicine physician before you fly. They can advise on prevention and give you a plan. What I will say: over-the-counter painkillers help a mild headache, and descending is the only true cure for worsening symptoms.

Driving-specific notes

Altitude affects you behind the wheel too. Reaction times dull, and a 4,700 m pass after a poor night’s sleep is not the place to discover that. My rules:

  • Do not drive the Pamir the same day you fly in from sea level. Give yourself the Kashgar night.
  • If a passenger feels unwell, the driver should stay sharp — swap roles if needed.
  • Watch for drowsiness; the thin air plus a warm cabin is quietly sedating on long plateau straights.

Who should be cautious

Most healthy people handle the Pamir fine with the slow-climb approach. But if you have uncontrolled blood pressure, a serious heart or lung condition, or a history of severe altitude illness, check with a doctor and consider keeping your route to the lower north (Ili, Sayram, Turpan). Children and older travelers do visit the Pamir, but build in more rest and watch kids closely — they may not voice a headache.

FAQ

At what altitude does sickness start in Xinjiang? Typically above 2,500 m. The Pamir towns (Tashkurgan ~3,100 m, Karakul ~3,600 m) and the Khunjerab approach (~4,700 m) are the main exposure; the Duku summit is about 3,400 m but you cross it, not sleep there.

Is it safe to drive to Khunjerab? Yes for most, if you climb gradually via Kashgar and Tashkurgan and return to sleep low. Do not attempt it the same day you arrive from low elevation.

What is the best way to avoid AMS? Spend a night in Kashgar first, ascend gradually, hydrate heavily, eat light, avoid alcohol the first nights, and sleep in Tashkurgan rather than at higher Karakul.

When should I descend? If a headache is severe, or you have vomiting, confusion, breathlessness at rest, or poor coordination — go down at once. Descent is the real cure.

Can I take medication to prevent it? Acetazolamide and dexamethasone exist, but only a physician should advise them for you. I never self-prescribe altitude drugs.

Does the Duku Highway cause altitude sickness? Brief mild effects are possible at the ~3,400 m summit, but since you cross rather than sleep high, serious illness is uncommon. The Pamir is the bigger concern.

Final word

The Pamir is worth every meter of climb, and altitude sickness is far more often a mild nuisance than a drama. Climb slowly, sleep low, and listen to your body — the roof of the world will be there when you are ready.
