I am very concerned about AMS(Acute Mountain Sickness); is it serious?
AMS is very common for most tourists when they first arrive on the high plateau. It can affect individuals differently based on their own health situation.
All of our itineraries are designed with altitude sickness in mind. We suggest our clients drink plenty of water, especially for the first few days, and do as little physical exertion as possible upon arrival. Most people need 2 to 3 days to acclimatize in Lhasa.
