Approximately 15km southeast of Zhōngdiàn is the Tiānshēng Bridge. Local Tibetans believe that the sulphur-rich water can cure any number of skin ailments and other health issues. There is a co-ed swimming pool and a natural sauna (inside a cave) that is divided into male and female sections. It’s possible to cycle here in about two hours or you could take a taxi (¥100 round trip).
