In the Yarlung Tsangpo Great Canyon lies the largest waterfall in China. On November 11, 1998, a science research team discovered for the first time the legendary grand waterfall in the Great Canyon, a typical riverbed waterfall named Yarlung Tsangpo Grand Waterfall.    

The team found a group of waterfalls in a place called Tsangpo Badong. Blocked by a huge rock in the middle of the water, the first waterfall falls into two streams, giving off smokes 100 meters high up in the sky. With a fall of 35 meters and a width of 62 meters, the waterfall is located in the main course of the Yalung Tsangpo River where the water makes a sharp S-turn. Following the river flow of about 600 meters, one can find the second waterfall, paralleled to the first one. It is the narrowest and also the rapidest one in the group, with a fall of 35 meters and a width of 35 meters. The rushing water dashes against stone cliffs, sending out a thunderous sound. Sprays of water seethe in a deep pool underneath the waterfall. The Great Canyon makes a right-angle turn in the triangular pool and becomes extremely narrow with the steepest slopes due to the change of terrene and abruptly speeding up currents. It seems that the waterfall is a necessary form of releasing its energy.    

Flowing 100 meters from the second waterfall, the Great Canyon forms a group of four cascades, with a fall of about 5 meters each. According to experts, these cascades were formed during mud-rock flows or landslides when rocks piled up along the river. From the first waterfall to the last cascade, the Yalung Tsangpo River drops down for over 100 meters, which means that the total fall of waterfall groups is no less than 100 meters.
