Si Mueang Mai

Si Mueang Mai is an administrative district in northeastern Thailand spanning eleven sub-districts with 118 villages. The township of Na Kham serves as the main commercial center where most shops and services are located.

The district underwent multiple administrative changes and office relocations between 1903 and 1957. These changes concluded with its establishment at its current location, Rong Kham Ma Chok.

Local markets in the district remain gathering places where residents and farmers trade fresh produce and handmade goods. These markets reflect how community life is organized around agricultural work and daily needs.

Local buses and private vehicles connect the district to neighboring areas and make it easy to move around. Arriving early in the morning helps you experience the local markets and their best selection.

The Mekong River forms the eastern boundary of the district and separates Thailand from Laos. This waterway serves as more than just a border; it is a vital resource for the local economy and daily community needs.
