Took a mid-morning flight to Lhasa. Arrived around 2 pm. The altitude of 12,000 feet impacts you immediately. You need to drink lots of water to stay hydrated. We also bought portable Oxygen canisters for the 800km bus ride to Mt. Kailash. We went to the hotel for lunch and then spent the rest of the day getting used to the altitude. Both Kathryn and I decided to take our altitude sickness pills and they seemed to have worked. Dinner at the hotel at night.
