Named for the King Norodom Sihanouk, then the ruler of Cambodia, Sihanoukville was built shortly after Cambodia gained its independence. Built to facilitate trade, Sihanoukville has since grown into a thriving port town, with booming industry including beer-brewing, agriculture, mining, and food processing. Among travelers, however, Sihanoukville is known for its beautiful beaches, which feature sprawling stretches of white sand, rough waves, palm trees, and friendly locals.
