Covering an area of 3,298 sq. kms., Ranong is located 568 kms. from Bangkok and about 300 kms. north of Phuket. It is bordered to the west by the Andaman Sea, to the north by Myanmar, to the east by Chumphon and to the south by Surat Thani. In the northeast of the province, the Kra Isthmus is the narrowest point of the peninsula, where just 44 kms. of land separates the Andaman Sea from the Gulf of Thailand. Ranong is the wettest province in Thailand, with over 4,000 mms. of rain per year, and also the country’s least populous province. The extended rainy period, which lasts for around 8 months each year, makes the period between December and April to be the best time to give Ranong a visit.
