South of Swan Lake, there is a lonely precipice standing erect, called Jianyan (Sword Cliff). It is over 500 meters high. Huge rocks are exposed to the air, and the steep slopes have little vegetation. The cliff was named for its sword-like outline.

South from Nuorilang Waterfall, Jiuzhaigou is divided into two parts. Extending toward the south is Zechawa Gully, with a length of about 17.8 kilometres. Walking along Zechawa Gully, you can enjoy scenic spots like Seasonal Lake, Multi-color Lake, and you will end your journey at Long Lake (elevation 3,100 meters.)
