Mae Hong Son province lies next to Myanmar, cradled by the Thanon Thong Chai and the Dan Lao Mountains. It is often called the Town of Three Mists because it seems to be perennially shrouded under misty air : ground fog in the rainy season and winter, and smoke from slash-and-burn farming in the summer.
Mae Hong Son is administratively in to 6 Amphoes and 1 King Amphoe namely : Muang, Mae Sa Riang, Mae La Noi, Pai, Khun Yuam, Sop Moei and King Amphoe Pang Ma Pha.
With an area of 12,681 square kilometers, Mae Hong Son can be reached from Chiang Mai either by Highway No.108 via Mae Sa Riang, for the distance of 349 kms. or Highway No.1095 via Pai which shortens the distance to some 274 kilometers.
