Tucked in the northwestern corner of Thailand, bordering the Shan state of Myanmar, is the mountainous, beautiful and once inaccessible frontier province of Mae Hong Son. The sole purpose for establishing Mae Hong Son was to herd and train wild elephants to supply to Chiangmai. An ancient trade route cut through the mountainous interior of Mae Hong Son. In 2003, Singaporean writer and adventurer Chan Joon Yee embarked on a solo expedition to explore this ancient trade route stopping over at villages where the elephant caravans once did.
