Ream National Park is a national park of Cambodia located 18 km (11 mi) from Sihanoukville city in the Prey Nob district of the Sihanoukville Province in south-eastern Cambodia. It was established in 1993, as the 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.

Ream National Park constitutes the south-east of Prey Nob district of the Sihanoukville Province bordering the Gulf of Thailand. The park enczompasses 210 km² (81 sq mi), divided into 150 km² (58 sq mi) of terrestrial and 60 km² (23 sq mi) of marine habitats.

The landscape of the park is mountainous with a range of habitats and ecosystems including mangrove forests, freshwater wetlands, sea-grass beds, evergreen forests, beaches, coral reefs, rivers, and islands.

The Park is divided by a freshwater river called the Prek Teuk Sap, which flows through the Park to the ocean. Land to the west of the river is dominated by two larger 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 277 m (909 ft), it is the highest peak within the Park. The other hill rises to a height of 196 m (643 ft). 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 band of degraded mangrove forest. The islands of Koh Thmei and Koh Seh comprise the eastern third of the park.

Wildlife found or reported in the national park includes, but is not limited to: rhesus monkeys, dugongs, turtles, dolphins, mouse-deer, Sarus crane, and pelicans. Vegetation habitats of the park include lowland evergreen forest, melaleuca forests, and mangrove forest. Despite all this, the National Park is a substantial local economic resource.

Almost 30,000 people or 5,500 households live in the five communes that overlap or border Ream National Park, and population growth rates are estimated at nearly 3%. Four of these communes are located on the boundary of Ream, and a total of 13 villages have land lying within the Park’s boundaries.

If you are looking for the most peaceful place on earth, there is no place like coming to Ream National Park. There is a wide array of activities that you can do to just enjoy your time in the sun. It is the perfect place to enjoy a great day in the sun while your cares simply drift away.

If you are looking to really live it up and add a little danger and adventure in your life, then Ream National Park is the perfect place for you. You will be amazed at the incredible things you can do and see while visiting there. You will have memories that will last a lifetime to say the least.

Whether you are on the mainland or one of the islands, one thing you will love is the amazing beaches. In many places they are the most perfect yellow you have ever seen, while in others you can enjoy the most incredible white beaches that a person has ever seen. While just a beautiful sight to behold, what makes them some amazing is the clean and pristine appearance of these beaches.

Consider that for generations this area is being left virtually unscathed. The economic and governmental struggles of Cambodia made it so that these lands were left virtually untouched. It was just those small villages that contained the only inhabitants, so there is no pollution, no large number of cars traveling through the area, no huge fishing boats or commercial barges, or large skyscrapers. You are not going to see big high-rise hotels or massive tourist centers. Keeping the natural look of this area was one of the important focuses of the developers of this area, and they have done just that.

The government has also been very careful to limit the number of tourists that can come to this area. The primary concern is the threatened and endangered animals that live in this tropical paradise, and they are not going to allow those plants and animals to be further at risk by a large tourist population that can tarnish their ecosystem.

What this means for you is that the land has not been scarred by man. You will not find litter everywhere, huge electrical towers and wires, massive streets, congestion, or dirty looking areas. Instead, you will find beach areas that look virtually untouched by man. The power that is supplied comes from solar panels that are discretely placed near the bungalows and resorts. This keeps them from being obtrusive upon vacationers who want to enjoy the scenery and not a bunch of manmade inventions.

A limited population also means plenty of area to stretch out and enjoy. You can go to places where there will be more people around, but if you want to find a secluded beach area to enjoy some solitary time it is very easy to do so. You will not have to search for very long or very hard to find an area where you may be the only person within 100 yards of yourself. This allows you to just enjoy some real peace and quiet.

You will find on the islands that the power is off from 11 pm to 5 am each day. Because solar power is the only source of electricity, the island resorts ensure that they are preserving the power that they have. This may seem like a major inconvenience, but once you get to see a look at the stars in the sky you will not be complaining for long.

With the majority of lights out around the area, you will see some of the most spectacular views on earth of the stars in the sky. You will not have huge lights that you would find in most vacation spots. This means that they will not interfere with your ability to see the sky as it was meant. It is a totally amazing view that will leave you breathless as you see God’s creation like never before.

A wide range of groups and individuals have converging and diverging interests or stakes in the park’s resources. Park authorities have to deal daily with all stakeholders. Consensus is not always possible since the resources of the park can only support limited levels of exploitation. Stakeholders are: local communities, commercial loggers, police, The Navy, Ministry of Environment, Rangers, United Nations Development Programme, land speculators, commercial fishermen, and tourists. Dubious land-lease concessions had mostly emerged from our around these groups of people. The subsequent hype gained momentum until dealings in highest circles of government were reported. 

In 2011, lawmakers issued a "law update" on Ream and other protected areas, stating: "The land area of 84.5 ha (209 acres) of the Ream National Park Zone shall be determined as a community area located in Ream commune, Prey Nub district of Preah Sihanouk province.

Any issuance of land title certificate in this community area shall be required to obtain a prior approval from the Ministry of Environment in compliance with the Land Law
