Ream National park is a national park of Cambodia located 18 km from Sihanoukville city in the Prey Nob district of Sihanoukville province in the south eastern Cambodia. It was established in 1993, when Cambodian government began to take action for the protection of the country's threatened natural resources. The national park's biological value is defined by its combination of rivers, forests, mangroves, estuaries, beaches, coral reefs, wildlife, and marine life. Prey Nob is bordering the Gulf of Thailand. The park encompasses 210 km, divided into 150 km for terrestrial and 60 km for marine habitats. The landscape of the park is mountainous with a rang of habitats and ecosystems including mangroves forests, fresh water wetlands, sea grass beds, evergreen forests, beaches, coral reefs, rivers and islands. The park is divided by a fresh water river call the Prek Teuk Sap, which flows through the park to the ocean. Land to the west of the river is dominated by two lager hills. These hills are separated by the Prek sampouch watercourse. Located on the most western side of the park is Phnom Mollou. At a height of 277m, it is the highest peak within the park. Other hills rises to a high of 196m. Between the hills and the estuary of the Prek Teuk Sap lies a narrow discontinuous belt of wetlands. These wetlands are protected by an even thinner than of degraded mangrove forests.
