Wiang Sa

Wiang Sa is an administrative district in Surat Thani Province that stretches from the Tapi River plains in the west to mountains in the east. The district is divided into three municipal townships, each managing its own local governance and services.

The area was originally influenced by the city-state of Nakhon Si Thammarat during the Srivijaya period and was later renamed Khlong Tan district in the 19th century. This change reflected the shifting administrative organization of southern Thailand.

Five sub-districts within Wiang Sa maintain their individual characteristics while contributing to the broader tapestry of southern Thai administrative traditions.

Visitors encounter a mixed landscape with river plains and mountains, which offers different activities depending on the season. The best time to explore is during the cooler months when temperatures become more comfortable.

Tai Romyen National Park spreads across the northeastern section and marks the boundary between flat plains and mountain terrain. This protected area shelters wildlife and plant species found only in this transition zone.
