The prettiest 2,142 km of China's
National Highway 318 runs over 5,000 km from Shanghai to Zhangmu, and the Sichuan–Tibet stretch is its crown jewel. You climb from 500 m at Chengdu to 3,600 m at Lhasa, crossing the Hengduan ranges, four of China's ten most beautiful mountains, and the headwaters of the Jinsha, Lancang, Nu and Yarlung Tsangpo rivers — all without ever leaving the tarmac for long.
