A note on altitude and young children
Kunming sits around 1,900 m and Dali around 1,970 m, which most children handle without issue. Lijiang is 2,400 m and Shangri-La is above 3,200 m, which is where we start asking questions. Our rule is to add at least two nights at lower altitude before going higher, keep the first day in a high town deliberately gentle, and never arrive directly by air from sea level to 3,200 m.
If you are travelling with a child under four, or anyone with a heart or respiratory condition, tell us before we plan the route — we will propose alternatives rather than reassure you vaguely.
