To the north and west it connects to a total of three states in the Union of Burma, namely the southern portion of Shan State, Kayah State, and Kawthoolei State, via the West Thanon Thongchai Mountains, and the rivers Salween and Moei. These formations serve as natural boundaries between the countries. To the south, it connects to the district of Tha Song Yang and Tak, via the rivers Yuam and Ngao, which serve as a provincial boundary. To the east it connects to the districts of Wiang Haeng, Chiang Dao, Mae Taeng, Mae Chaem, Hot and Omkoi in Chiang Mai Province, via the central and east sections of the Thanon Thongchai mountain ranges, which serve as a boundary between the two provinces.
