There are many things to do in Surat Thani Province - the largest of the southern provinces (changwat) of Thailand. It lies on the western shore of the Gulf of Thailand. Surat Thani means 'city of good people', a title given to the city by King Vajiravudh (Rama VI); Surat Thani is therefore the sole province in Southern Thailand for which the native name is in the Central Thai language.
Geographically, the centre of the province is the coastal plain of the Tapi River, mostly grassland interspersed with rubber trees and coconut plantations. In the west are the limestone mountains of the Phuket range which are mostly covered with forest. Khao Sok National Park is found there. To the east the hills of the Nakhon Si Thammarat (or Bantat) mountain range start to rise, protected in the Tai Rom Yen National Park. The total forest area is 3,764 km2 (1,453 sq mi) or 28.8 percent of provincial area.
