Ngari (also Ali) prefecture in northwestern Tibet is known as "the roof of the world" for it is situated at an elevation of 4,500 meters above sea level. It's the place where the Himalayas, the Gangdise, the Kunlun Mountains and Karakorum Mountains meet. This area is dotted with beautiful lakes and rivers, great mountains and glaciers, vast grasslands, spectacular snow mountains and clay forests.

Sparsely populated, Ngari is a paradise for wild animals, such as yaks and Tibetan antelopes. It is also a popular tourist destination with many famous natural and historical sites, like the ruins of Guge Kingdom, Toling Temple, the holy Mt. Kailash and the sacred Lake Manasarovar. The last two are symbolized as the spiritual center of Buddhists.
