Chiang Rai is the northernmost province of Thailand. Neighbouring provinces are Phayao, Lampang and Chiang Mai. In the north it borders Shan State of Myanmar and Bokeo of Laos.

The province is rich in tourism resources in terms of natural attractions and antiquities, evidence of its past civilisation. It is also home to various hilltribes who follow fascinating ways of life. Chiang Rai is also a tourism gateway into Myanmar and Laos.
