Yading is a national level reserve in Daocheng County, in the southwest of Sichuan Province, China. Unknown to the outside world until the late 1990s, it is a mountain sanctuary and major Tibetan pilgrimage site comprising three peaks sanctified by the 5th Dalai Lama. The peaks are seen as emanations of the three boddhisatvas Chenrezig, Jampayang and Chenadorje, with Chenrezig being the highest peak at 6032 meters above sea level. It is served by Daocheng Yading Airport.

Daocheng Yading actually refers to Yading Nature Reserve in Daocheng County. In 1928, American botanist and explorer Joseph Rock arrived there and later published an article and pictures of the place to introduce Yading to the world. The most renowned attractions of Yading are three holy peaks, which were said to be blessed in the 8th century by Buddha Padmasambhava when he projected his divine light onto the range and named the peaks. The southern peak, Jambeyang, and the eastern one, Chanadorje, both stretch up 5,958 meters. The northern peak, Chenresig, reaches 6,032 meters. Many Tibetans long to embark on a pilgrimage to this holy range.
