Ping River
The Ping River, one of the main tributaries to the Chao Phraya River, originates at Doi Thuai, in the mountains of the Daen Lao Range in Chiang Dao District. The Taeng River, a river that has its source in the mountains of the Daen Lao Range in neighbouring Wiang Haeng District, also flows through Chiang Dao District on its way to its confluence with the Ping River in Mae Taeng District.
