Sihanoukville, also known as Kampong Saom (កំពង់សោម) or Preah Sihanouk is a coastal port city in Cambodia and the capital of Preah Sihanouk Province, at the tip of an elevated peninsula in the country’s south-west on the Gulf of Thailand. The city has a string of beaches along its coastline and coastal marshlands bordering Ream National Park in the east. It has one navigable river, the mangrove-lined Ou Trojak Jet, running from Otres Pagoda to the sea at Otres. Several sparsely inhabited islands under Sihanoukville’s administration are near the city.
