Mae Sai

Mae Sai is an administrative district in northern Chiang Rai Province that stretches along the Myanmar border. The area is divided into several subdistricts and contains towns, villages, and important crossing points where the border region meets Thai territory.

The district was formed in 1939 from two communities separated from Chiang Saen and became a full district in 1950. This administrative change was part of efforts to organize the Thai borderlands.

Thai and Shan traditions blend visibly through local shops, food, and crafts that reflect both cultures. Border communities here share customs and daily routines that have developed from generations of cross-border contact.

The area functions as a main crossing point between Thailand and Myanmar with a direct border bridge. Visitors should be aware of the border location and prepare appropriate documents depending on their travel plans.

The Daen Lao mountain range borders this area with peaks like Doi Tung, topped by the ancient Wat Phra That temple. This mountain is both a natural boundary and a destination where visitors can hike and enjoy sweeping views of the border region.
