With a land area of 215 square miles, Phuket Island is about the same size as Singapore, making it Thailand's largest island. Known as the "Pearl of Thailand," this beautiful retreat offers pristine beaches, lush vegetation, traditional villages, and seascapes of huge limestone pillars that tower over the turquoise waters of Phang-Nga Bay. Apart from tourism, much of the province's wealth derives from tin production, which started back in the 16th century.
