A quiet and tranquil province, Nan nestles in a verdant valley in northern Thailand. About 668 kilometres from Bangkok, it covers an area of 11,472 square kilometres and is made up of the following districts: Mueang, Wiang Sa, Na Noi, Pua, Chiang Klang, Tha Wang Pha, Thung Chang, Mae Charim, Ban Luang, Na Mun, Santi Suk, Bo Kluea, Chaloem Phra Kiat, Song Khwae, and Phu Phiang.
The people of Nan descend from the Lan Changs (Laotians). Their forebears moved to settle around present-day Pua district which is rich in rock salt deposits, about 700 years ago at the time when Sukhothai was becoming the kingdom of the Thais. They subsequently moved south to the fertile Nan River basin which is much more extensive.
Nan's history is deeply involved with its neighbours, in particular Sukhothai which played an important role in both political and religious terms before Nan became a part of Lanna, Burma and Thailand in that order. Today Nan is still the home of numerous Thai Lue and other hilltribes who retain highly interesting customs and traditions.
