Altitude is the detail most Yunnan itineraries forget. Kunming is moderate, Dali is mild, but Lijiang, Shangri-La, and the mountains above them are high enough to affect sleep, appetite, and energy. The risk is not usually serious altitude sickness; it is a few wasted days of headaches and bad nights. A gradual route and a slow first day prevent most of it.
Checklist
- Know the altitude of every stop on your route
- Keep the first plateau day free of strenuous activity
- Carry water and a warm layer; altitude dehydrates and chills
- Know the descent route from any high point
- Check insurance coverage for high-altitude travel
What to expect at each level
Below 2,500 metres, most travelers feel nothing beyond dry air and faster breathlessness on stairs. Around 2,400–2,800 metres — Lijiang, Lugu Lake — mild headaches and poor sleep are common but manageable. Above 3,000 metres — Shangri-La and the plateau — the effects are more noticeable, especially on the first night.
Serious altitude illness (fluid in the lungs or brain) is rare at these elevations but possible, especially if you ascend quickly or have a pre-existing condition. The key signs are a persistent headache that does not respond to painkillers, nausea and vomiting, confusion, or breathlessness at rest. If these appear, descend.
- Kunming 1,890 m · Dali 1,970 m · Lijiang 2,400 m
- Shangri-La 3,160 m · Pudacuo 3,500 m · Meili viewpoints 4,000 m+
A simple acclimatisation plan
Climb gradually. Spend a night or two at 2,000–2,500 metres before going above 3,000. On arrival at altitude, take the first day slowly: short walks, no alcohol, plenty of water, and an early night. Avoid strenuous hiking or cable cars to high viewpoints on day one. If you feel unwell, do not push on to a higher stop.
People with heart or lung conditions, pregnant travelers, and anyone with a history of altitude illness should talk to a doctor before coming. Portable oxygen is sold in tourist towns but is not a substitute for descent. Travel insurance should cover evacuation if you plan to go above 3,500 metres.
