The Yarlung Zangbo River, originating from a glacier on the north Himalayas, is the highest river on the earth with an average altitude of more than 3,000 meters. Its total length is over 2,900 kilometers. Running 2,057 kilometers in Tibet, it ends up in India, where it is named as Brahmaputra. The river is the largest river in Tibet and the sixth longest in China.

The Yarlung Zangbo River makes a very sharp turn when it meets the snowcapped Mt. Namcha Barwa, which soars 7,782 meters. The turn is so sharp that a great canyon larger and more spectacular than the Grand Canyon of Colorado River forms. The Great Canyon of Yarlung Zangbo's depth reaches 5,382 meters and it has a total length of 496.3 kilometers, about 56 kilometers longer than the Grand Canyon in Colorado.

The Yarlung Zangbo Great Canyon is the world's largest canyon, covering 17,000 square kilometers. It has 17 snow-clad peaks above 6,000 meters.
