|The largest province of the South located 685 kilometers from Bangkok is Surat Thani the province with a name that literally means "City of the Good People". A former capital of the Srivijaya Empire, the province covers an area of approximately 12,891 square kilometers. Surat Thani Province borders the Gulf of Thailand to the north and east, Chumphon Province to the north, Nakhon Si Thammarat and Krabi Provinces to the south, Phang-Nga and Ranong Provinces to the west and Nakhon Si Thammarat Province to the east.
High plateaus and forested mountains are located to the west of the province, while there are low basins in the center and along the eastern coast. This topography has created 14 river basins including Tapee, Pum Duang, Tha Thong, Tha Krajai, Chaiya, Tha Chang which are the most important basins. All rivers in Surat Thani flow east of the province to the Gulf of Thailand.
The numerous islands along the coast makes Surat Thani (often known as Surat in short) a perfect hideaway for vacationers from around the world. The ideal destination for many is the Penang-sized Ko Samui, Thailand's third largest island, and its neighbour Ko Pha-ngan a celebrated island that hosts the biggest beach full moon party. North of Ko Pha-ngan is Ko Tao, renowned for its excellent coral reefs. To top it all is the dazzling 250-square-kilometer Ang Thong Marine National Park, where a stunning archipelago awaits to greet visitors with their charming palm-fringed beaches, crystal clear water and colorful coral reefs. The best time to enjoy one of these islands to the fullest is from April November.
