On the old road between Gyantse (4040m) and Lhasa, the dazzling Yamdroktso (4441m) can be seen from the summit of the Kamba-la pass (5030m ). In clear weather, the lake is a fabulous shade of deep turquoise. Leaving Yamdroktso is as spectacular as arriving, since you have to cross the 5045m Karola, with its awesome roadside views of the Nojin Kangtsang Glacier.
