Spiti, the high passes of Himachal and the upper meadows of Kashmir are breathtaking – literally. Above about 2,500 m, the air holds less oxygen and some travellers develop acute mountain sickness (AMS). The good news: with sensible planning, most people enjoy these trips without trouble. Here are our practical altitude sickness tips.
*This article is general travel guidance, not medical advice. Please consult your doctor before a high-altitude trip, especially if you have heart, lung or blood-pressure conditions, or are pregnant.*
- AMS can start above about 2,500 m
- Kaza is about 3,800 m; Key Monastery and Kunzum Pass are above 4,100 m
- The best prevention: gradual ascent and rest
- Our Spiti route climbs gradually through Kinnaur
Common symptoms
- Headache
- Loss of appetite or nausea
- Tiredness and weakness
- Dizziness
- Trouble sleeping
Symptoms usually appear 6–24 hours after arriving at altitude and often settle with rest.
Warning signs – descend and seek help
- Severe headache that doesn’t improve
- Confusion, unsteady walking or extreme drowsiness
- Breathlessness at rest or a persistent cough
These can indicate serious conditions (HACE or HAPE) that need immediate descent and medical care.
How to prevent altitude sickness
- Ascend gradually: this is the single most important factor. Our Spiti route enters through Kinnaur, climbing over several days.
- Rest on arrival: take it easy on your first afternoon at a new altitude.
- Hydrate: drink water steadily through the day; avoid overdoing tea and coffee.
- Avoid alcohol and smoking for the first days.
- Eat light, carbohydrate-rich meals.
- “Climb high, sleep low” where possible.
- Medicines: some travellers use acetazolamide (Diamox) on a doctor’s advice – never self-medicate.
- Keep warm – cold makes you feel worse.
Who should be careful?
- People with heart or lung disease, high blood pressure or anaemia.
- Pregnant women.
- Infants and very young children.
- Anyone who has had AMS before.
