Altitude sickness, also known as Acute Mountain Sickness (AMS), is the most common concern for travelers visiting Tibet. Because Lhasa sits at an elevation of 3,650 meters (11,975 feet), the atmospheric pressure drops, and there is roughly 35% less oxygen in each breath compared to sea level. However, with proper preparation and a sensible itinerary, almost anyone can acclimatize safely.
During your first 24 to 48 hours in Lhasa, it is completely normal to experience mild symptoms as your body adjusts. These include:
These symptoms usually fade by day 3. If symptoms become severe (severe vomiting, persistent coughing, or inability to walk), medical attention and supplemental oxygen are required immediately.
We design our itineraries with a built-in slow acclimatization curve. To ensure maximum peace of mind, all of our private tour cars and commercial travel buses in Lhasa are equipped with professional oxygen supply systems and emergency first-aid kits.
Our local guides and 24/7 English-speaking ground managers are fully trained in altitude safety and maintain direct lines to local medical facilities if required.

While the train helps, the mountain passes it crosses are over 5,000 meters high, and the train cabins are artificially pressurized. Whether you fly or take the train, the golden rule remains the same: Plan at least 2 full days of rest in Lhasa before heading to higher areas like Shigatse or Everest Base Camp.
