The Shuzheng Valley is the northern (main) branch of Jiuzhaigou. It ends after 14.5 km at the Y-shaped intersection of the three gullies. Going downhill from the intersection to the mouth of the valley, visitors encounter the following:
Nuorilang Fall, near the junction of the valleys, are 20 m high and 320 m wide. They are reportedly the widest highland waterfall in China, and one of the symbols of Jiuzhaigou.
Nuorilang Lakes and Shuzheng Lakes are stepped series of respectively 18 and 19 ribbon lakes formed by the passage of glaciers, then naturally dammed. Some of them have their own folkloric names, such as the Rhinoceros, Unknown, and Tiger lakes.
Sleeping Dragon Lake is one of the lower lakes in the area. With a depth of 20 m, it is notable for the clearly visible calcareous dyke running through it, whose shape has been compared to a dragon lying on the bottom.
Reed Lake is a 1375m-long, reed-covered marsh with a clear turquoise brook zigzaging through it. The contrast is particularly striking in the autumn when the reeds turn yellow.
