The infrastructure of the tourist industry is still very basic in this remote country. Please do not expect the standard you are accustomed to in the West. The tour starts from Thamel, Kathmandu, Nepal. Enroute, breakfast stop is made at Dhulikhel. The Tibetan Guide will meet you here and will take care of your entire tour arrangement.
Mineral water is available throughout the trip.
Clothing Casual wears and comfortable walking shoes are the rule for Tibet. Be sure to bring warm clothing as nights and early mornings can be quite chilly to downright cold in winter months. Bring all the film, medicine, cosmetics, personal toilet items, etc. that you will need from home as these are difficult if not impossible to obtain in Tibet. A small first aid kit is also a good idea. Also quite useful is Kathmandu Lhasa route map, to know where you are going and have been each day.
