Along the Nujiang into Tibet

North of Bingzhongluo the road ends and Tibet begins: a narrow dirt track, still wide enough to carry supply trucks, follows the Nujiang up to Chawalong, a small commercial center for the scattered Tibetan villages beyond. Beyond it, transport is by caravan only. The trail winds perilously along arid slopes, sometimes with spectacular views of the snow mountains, until it reaches Bitu, connected by road to Tibet.
