Muang Ngao

Muang Ngao lies in the northern Thai highlands between the country of Phayao and the valleys leading south towards Lampang and Phrae. Local traditions remember an old town called Mueang Ngoen in the Ngao valley, associated with the ruler Ngam Mueang of Phayao. The Ngao River and its tributaries descend through the surrounding hills, giving the valley its name and connecting settlements along its course.
