Just 18km east of Sihanoukville, Ream National Park – also known as Preah Sihanouk National Park – comprises 150 sq km of primary forests (mostly lowland evergreen forest and mangrove swamps) and 60 sq km of marine habitats. It’s home to breeding populations of a number of regionally and globally endangered birds of prey, including the Brahminy kite, grey-headed fish-eagle, and white-bellied sea-eagle – look for them soaring over Prek Toeuk Sap Estuary, which is salty in the dry season and freshwater in the wet season. Endangered birds that feed on the mudflats include the lesser adjutant, milky stork, and painted stork.
Ream National Park becomes the best beach in South East Asia. Therefore, we have sea festival every year at Sihanoukville. The Beach is the best refreshment place for international and national tourists.
