Doi Wiang Pha National Park's high mountains, extending northwards, are considered as natural borders marking the boundary between Chiang Mai and Chiang Rai provinces. Doi Wiang Pha is the highest peak in this National Park, at an elevation of 1,834 metres above mean sea level. This forested area serves as the source of major streams flowing into Fang River and tributaries of the Lao River, such as Mae Fang Luang stream, Mae Fangnoi stream and Yangmin River.
