Travelling from Chengdu to Lhasa is one of the great rail journeys, and also one of the trips that requires the most preparation. The railway climbs onto the Tibetan plateau over many hours, the altitude at the other end is significant, and the documentation requirements are stricter than anywhere else in China.
This guide covers the two ways to make the journey, what the altitude does to your first day, and what to arrange before you book anything.
Fast, and the choice if your time is limited. It also means arriving at altitude abruptly, with no gradual adjustment, which makes the first day harder than it needs to be.
A long journey, and part of the point of going. The train climbs gradually, which gives some acclimatisation benefit, and it supplies oxygen on board. It is also the more memorable option by a distance.
Take the train if you have the time and want the acclimatisation. Fly if you are short on days and prepared to be careful for the first 24 hours.
| Option | Advantage | Drawback |
|---|---|---|
| Railway | Gradual ascent, scenery, oxygen on board | A long journey |
| Flight | Fast | Abrupt altitude exposure |
| Road | Flexible, staged acclimatisation | Very long, demanding conditions |
Travelling to the Tibet Autonomous Region requires permits arranged in advance, and for most foreign visitors these are organised through an agency as part of a booked arrangement rather than obtained independently. Requirements change, so confirm current rules with your operator before booking flights or trains.
Independent travel without the correct documentation is not possible. This is the single thing that most often goes wrong with a Chengdu to Lhasa plan.
Do nothing strenuous. Rest, drink water, avoid alcohol, and let the day pass. Most visitors feel something – headache, poor appetite, broken sleep – and most improve substantially after a day of rest.
Worsening breathlessness at rest, confusion, or a persistent cough needs medical attention rather than more rest. This is general information and not medical advice; anyone with heart, lung or other serious conditions should consult a doctor before travelling.
Put the Potala Palace and the major monasteries later in the trip rather than on day one. They involve climbing, and doing them while unacclimatised is unpleasant and unnecessary.
Layers for large temperature swings, sun protection at altitude, and any medication you have discussed with a doctor beforehand. The sun on the plateau is far stronger than in Chengdu.
Bring patience for the administrative side. Documentation checks happen at several points and they take time.
| Item | Detail |
|---|---|
| Documents | Arranged in advance; requirements change |
| First day | Rest, hydrate, no alcohol |
| Best season | Generally the warmer months for access and comfort |
| Sun | Strong at altitude; protect accordingly |
Not without the required permits arranged in advance. Most visitors book through an agency that handles this.
Usually, because the ascent is gradual and oxygen is available on board. Flying means arriving at altitude with no adjustment.
Variable. Most people feel mild effects and improve within a day. A minority have a harder time and should seek medical advice.
Three at minimum, with the first kept light and the major climbing sights saved for later.
