About Chiang Mai

Learn more about the host city, Chiang Mai.

Chiang Mai (เชียงใหม่) is the hub of northern Thailand. On a plain at an elevation of 316 m, surrounded by mountains and lush countryside, it is much greener and quieter than the capital and has a cosmopolitan air and a significant expatriate population, all factors which have led many from Bangkok to settle permanently in this "rose of the north".
