Proper hydration is critical to acclimatization. The journey from Kathmandu to Lhasa by road should be viewed as an adventure , not sightseeing tour by bus. The road itself was poorly constructed and is prone to landslides , particularly from June through September. It can be very dusty and some kind of face mask is a good idea. As you drive to altitudes of over 17000 ft. at some points altitude sickness becomes a real possibility and most will feel some symptoms.
Hotels are basic with showers, flush toilet, a small shop, a restaurant and laundry facilities only.
Food is not readily available enroute until the stopover hotels are reached. We recommend you carry packed lunch from the hotels. We suggest you bring a canteen or water bottle with purification tablet or a water filter pump and refill your bottles at every opportunity. Full travel insurance coverage, particularly for trip cancellation and interruption is strongly recommended. The unit of currency for foreigners is Yuan.
