Phayao is a city in the Northern River Valleys of Northern Thailand.
Virtually enveloped by mountains and valleys, Phayao is a peaceful province. Though with only modest facilities and conveniences, it is an enchanting community with delightful natural beauty and fascinating religious sites. Dating back to more than 900 years, it used to be an independent state with its own rulers before it became a part of the Lanna Thai kingdom in mid-14th century.
Phayao is about 691 kilometres from Bangkok and covers an area of 6,335 square kilometres.
