Isaan (อีสาน; also Isan, Isarn and even Esarn) is Thailand's largest region, consisting of 20 provinces. Despite having 30% of Thailand's population, this region receives less than 3% of Thailand's tourist dollars. It is a multicultural region where Laos, Cambodia and Thailand meet, and has a rich history and great food. In particular, it is home to Thailand's second-largest ethnic group, the Thai Lao.
