In 1993, King Norodom Sihanouk appointed the establishment of Ream National Park. One distinctive feature of this national park is its surroundings, encompassed by mangrove land in inland estuaries.

Founded by King Norodom Sihanouk in 1993, this national park holds historical significance as the first in peacetime Cambodia and is notably important. Its sandy banks and forested peaks served as a strategic location for the Vietnamese uprising against the Khmer Rouge in 1979. In many respects, Ream appears to have undergone minimal change since that period. The lush forests and picturesque beaches remain largely undiscovered, with only a few villages and guesthouses situated within the park's boundaries. Despite the addition of some industrial elements, such as oil and gas fields and a substantial military base, the park's beauty persists, and traversing through it provides a genuine sense of Cambodia.
