Daocheng, a county in the southwest of Sichuan province, is mainly inhabited by Tibetans. Broad valleys, lush pastures and imposing mountains make the county a fantastic place for visit and hike. Surrounded by snow mountains and forests, Daocheng is often referred to as "the last pure land in our blue planet." The three-day hike from Daocheng to Yading takes you through some of the quietest and purest natural scenery on earth.[Photo/jinnanz/bbs.fengniao]
