Sihanoukville Province (Preah Sihanouk)

Geography and natural features

Sihanoukville combines coastal plains, mangrove estuaries and offshore islands. Several reefs and sandy beaches attract visitors, while islands such as Koh Rong and Koh Rong Sanloem are known for clearer waters and tourism development. Ream National Park, which includes mangroves, lowland forest and marine areas, protects parts of the coastline and islands including Koh Thmei and Koh Seh.

History and name

The area was historically called Kampong Som before being reconstituted as a province and later renamed to honor King Norodom Sihanouk. The modern port and urban settlement expanded in the 20th century as Cambodia developed maritime links to international trade. Historical layers include fishing and coastal communities that predate large-scale industrialization and tourism.

Economy and infrastructure

The province's economy rests on a few pillars: the deep-water port, fisheries and growing tourism. The Sihanoukville Autonomous Port handles much of Cambodia's maritime cargo and has driven related logistics and industrial activity. An international airport and road connections link the province with other parts of the country. In recent years significant foreign investment—particularly in real estate and leisure facilities—has accelerated construction and urban change.

Tourism, conservation and challenges

Beaches and islands make Sihanoukville a major domestic and international destination. Activities include beach tourism, island hopping and marine recreation. Conservation areas such as Ream National Park aim to protect mangroves, coral and wildlife, but the province faces challenges from rapid development, habitat loss, waste management and pressures on marine resources. Policy makers, local groups and international partners are engaged in managing these competing needs.

Notable facts and distinctions

• It contains Cambodia's only deep-water seaport, an important national logistics asset.
• The provincial capital shares the same name, Sihanoukville, which can cause confusion between city and province references.
• The province includes several popular islands and a national park that combine terrestrial and marine conservation values.

Sihanoukville's experience illustrates common coastal-development dynamics: strategic infrastructure and attractive natural assets foster economic opportunity, while rapid change creates social and environmental trade-offs. For background on the province's renaming and legacy see historical notes.
