Ream National Park was established in 1993 to the government of Cambodia to conserve and protect the endangered wildlife and forests in the areas along the coastline of the Gulf of Thailand. It is the first national park founded and one of the seven such parks in the country, which also includes popular nearby Koh Thmei, Koh Seh and 19 other smaller islands. The thin stretch of land spreads for over 15,000 square kilometres overlooking the ocean is home to coastal rainforests, fresh-water wetlands, salt-water mangroves, beaches, coral reefs along with white sand beaches.
PrekTeuk Sap river separates the National park, which flows directly to the ocean on the other end. On the west side of this river are two hills, the enormous hill being 900-meter high Phnoum Mollou. It is the highest point in the park and offers splendid bird views of the coastline and forests from the top, which is a famous landmark for tourists. A waterway course PrekSampouch lies between these hills, which is known for all watersport activities. On the other end of the river is the PrekTeuk Sap estuary, a narrow scenic stretch of water.
The park is home to more than 150 endangered birds of prey, different species of storks, kite, various types of wild eagles, seagulls, pelicans, cranes and more. Wildlife consists of tigers, rhesus monkeys, deers, macaques, and bears. The long stretch of coastline spreading over 6000 hectares is home to abundant marine life, including coral reefs, dolphins, many species of turtles and fish.
Some of the white sand beaches in the national park are occupied with resorts and clubs. Also, more than 30,000 people live in the nearby communities bordering the park, all threatening the conservation. Restricting their influence, spread and damage the national park has been putting commendable efforts in preserving the vibrant ecosystem.
