The Lao River originates in the Phi Pan Nam Range[2] and flows initially northwards across Wiang Pa Pao District and then northeastwards through the districts of Mae Suai, Mae Lao and Mueang Chiang Rai passing just south of Chiang Rai city.

The Suai River, which gives its name to the Mae Suai District, is one of the main tributaries of the Lao River.
