Best time to go: From July to October is the season for entering the canyon.

Yarlong Tsangpo River, originating from a glacier on the north Himalayas, is the highest river on the earth with an average altitude of more than 4,000 meters (13,120 feet). Running 2,057 kilometers (1,275 miles) in Tibet, it finally flows into India, where it is named as Brahmaputra. The river is the largest river in Tibet and the sixth longest in China. It makes a very sharp turn when it meets snow capped Mt. Namcha Barwa, which soars 7,782 meters (25,525 feet) up to the sky and stays in clouds. 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 Yarlong Tsangpo River's depth reaches 5,382m (17,657 feet) and it has a total length of 496.3 kilometers (307.7 miles).

The newly discovered world largest canyon lies at the junction area of Himalayas, Hengduan Range and Mt. Nyainqentanglha. The depopulated area covers 17,000 square kilometers (6534 square miles), having rich tourism resource. The great canyon has 17 snow-clad peaks above 6,000 meters (19680 feet), however the river drops severely to 155 meters (508 feet) only at its end. Wet wind from India plain flows into the area and builds an Edan of plants and animals undisturbed.

The Yarlung Zangbo River originates from the middle section of the northern slope of the Himalaya Mountain with an elevation of more than 6,000 meters. It turns south suddenly in Mainling County and cuts the Himalaya Mountain into two sections. Then the river runs through a narrow passage between the two 7,000 meter high peaks of Namjagbarwa and Jialabailei. Its flow averages 1,000 cubic meters per second year round. In one section less than 1,000 meters, the drop is more than 300 meters and its current velocity is more than 18 meters per second. Here is the Yarlung Zangbo Canyon, the first one in the world. Standing by it, you will feel the fascination of the nature, including the precipitous cliffs, hot springs, waterfalls, primeval forests, rare plants and animals.

The complex and unique geographic and climate conditions provide Tibet a museum of wildlife. Rare and unique plants and animals, existing only in this area on the earth, are well reserved.

At the deepest of the great canyon, Menba and Luoba people live their primitive life on the purified land on the earth.

It takes one month to go through the Yarlung Zangbo Canyon. From July to October is the season for entering the canyon.
