Mount Zheduo (Chinese: 折多山, Standard Tibetan: རྒྱུ་ལ་ཁ, romanized: rgyu la kha) belongs to the remnants of the Gongga Mountain in the middle of the Daxue Mountains, towering over the western section of the Sichuan Basin. Mount Zheduo is the watershed between the Dadu River and the Yalong River, and is also the dividing line between Han and Tibetan culture.

To the west of the Mount Zheduo is the traditional Kham Tibetan area. The Zheduo Pass (Standard Tibetan: རྒྱུ་ལ་རི་བོའི, romanized: rgyu la ri wo) that National Highway 318 needs to cross is located at an altitude of 4,298 m (14,101 ft) above sea level; it is the first mountain pass on the road that needs to be crossed over 4,000 meters, hence the title "The First Pass of Kham".
