This trekking tour starts from Damxung, passes through, beautiful meadows, glaciated valleys and mountains of the Nyenchen Thanguha range to the pebbled shores of the lake. After leaving Damxung valley, the route wends its way through a rocky defile, the gateway to a high-elevation forest where dwarf willow and rhododendron are dominant species. A number of stream crossings await you. A tundra-filled upper valley gradually climbs to the Kyang-la (Onager pass), followed by a steep descent onto the Changtang plains. Fantastic views of sparkling Namtso and Tashi Do are visible from many vantage points on the trail. And colourful drokpa camps dot the way.
