Lock Trail Trek: Discover the Hidden Shangri-La

Named after American explorer Joseph Rock, the Lock Trail starts in Muli Tibetan Autonomous County, Liangshan Prefecture, Sichuan, and ends in Yading Village, Daocheng County. Preserving its primitive natural landscape, the trail takes hikers deep into three sacred mountains, offering "breathtakingly beautiful" scenery. With high difficulty, the best time to hike is September to October.
