Last updated: 2026-09-15

Preferred months for this journey: May, June, September, October. Check the seasonal notes before choosing your dates.

The most comfortable corridor window for long outdoor visits. Reserve trains and timed attractions, and confirm live wind, heat and closure notices.
Dunhuang and the western corridor can be extremely hot. Put desert and exposed heritage visits early or late, keep indoor alternatives and confirm heat or sandstorm restrictions.
The route remains possible, but western Gansu is cold and exposed. Check snow, wind and rail disruption, and confirm each attraction’s current winter hours.
Spring is workable but exposed sites can be windy or dusty. Confirm the forecast, rail operation and current attraction hours before each long leg.
