This trip requires a minimal fitness level. There will not be any rigorous hiking, but there will be some short walks. The walks are sometimes uphill and on mountainous terrains.
Keep in mind that we will be traversing high altitudes and it can making walking/hiking more challenging. Altitude sickness affects people differently, and it does not depend on fitness level or age.
The capital city Lhasa itself stands at 3,550m above sea level, and Everest Base Camp looms at 5,088m. At such dizzying heights, it can be easy to suffer from AMS (Acute Mountain Sickness) if you don’t take the time to acclimatise to the conditions.
Symptoms of AMS include light-headedness, nausea, short of breathe and headaches. Be sure to get some Diamox (Acetazolamide) before your trip and start the medication at least one day before landing in Lhasa. Give yourself plenty of time to rest and acclimatise in Lhasa before you start exploring.
