Sihanoukville's many beaches and nearby islands make it Cambodia's premier seaside resort with steadily rising numbers of national visitors and international tourists since the late 20th century. As a result of its economic diversity, the region's natural beauty and the considerable recreational potential, a constantly increasing number of seasonal and permanent foreign residents make Sihanoukville one of the most culturally varied and dynamic population centers in Cambodia. As of 2014 the tourism sector remains insignificant in comparison with neighboring Thailand. Sihanoukville's future will largely be defined by the authorities' capability of a successfully balanced management in order to protect and conserve natural resources on the one hand and the necessities of urban and insular development, increasing visitor numbers, expanding infrastructure, the industrial sector and population growth on the other.
Despite being the country’s premier sea side destination, after decades of war and upheaval the town and its infrastructure remain very much disjointed and architecturally unimpressive. Infrastructure problems persist, in particular related to water and power supply, while international standard health facilities remain limited.
Cambodia and the capital city of Sihanoukville Province, located at the tip of an elevated peninsula in the country's south-west at the Gulf of Thailand. The city is flanked by an almost uninterrupted string of beaches along its entire coastline and coastal marshlands bordering the Ream National Park in the East. The city has one navigatable river, the mangrove lined Ou Trojak Jet running from Otres pagoda to the sea at Otres. A number of thinly inhabited islands – under Sihanoukville's administration – are in the city's proximity, where in recent years moderate development has helped to attract a sizable portion of Asia's individual travelers, young students and back-packers.
The city, which was named in honour of former king Norodom Sihanouk, had a population of around 98800 people and approximately 69,700 in its urban center in 20012. Sihanoukville city encompasses the greater part of six communes (Sangkats) of Preah Sihanoukville Provinces. A relatively young city, it has evolved parallel to the construction of the Sihanoukville Autonomous Port, which commenced in June 1955, as the country's gateway to direct and unrestricted international sea trade. The only deep water port in Cambodia includes a mineral oil terminal and a transport logistics facility. As a consequence, the city grew to become a leading national center of trade, commerce, transport and process manufacturing.
