Acclimatisation in Tibet

 All the travellers visiting Tibet must be aware of Mountain sickness before their Tibet travel. Inadequate acclimatization in Tibet could lead to altitude Mountain sickness in any traveller going to 2,500 meters or higher. Mountain sickness can be severe and can affect your holiday in Tibet. If not taken care of, it would lead to death.
