Definitely! We will carry oxygen cylinder for emergency issues. And local hospitals are ready to deal with any emergency cases. We will take good care of every customer during the tour. The rise of altitude is not immediate and it is a gradual process. So if you feel anything wrong, you can inform your Tibetan guide instantly and we may need to adjust the Tibet tour program and wait for you to feel better and take optional easier tour program accordingly. And if anyone feels very uncomfortable, we will let him stay in the relatively low altitude places and will catch him/her later when we finish the high altitude tour.
