Amnye Machen ("Grandfather Scar") is one of the four most sacred mountains in Tibet. Ranging as high as 6,828 m/20, 605 ft, the mountain stands as an iconic symbol of Amdo Province. Revered by Tibetan Buddhists, Amnye Machen, is a holy site where pilgrims pay homage by walking the full distance—approximately 105 kilometers—around the mountain. For countless centuries, the mountain's meadows and grasslands have sustained generations of nomadic Tibetans. With breathtaking views, rustic villages and Buddhist reliquary, trekking around the mountain takes 7-10 days and is best done in the months between June and September.
