Preah Monivong National Park, known as Bokor National Park, was established by Royal Decree on 01 November 1993 and covers an area of 140,000 hectares (1,400 square kilometers) that span three southern provinces: Kampot, Kompong Spue and Preah Sihanouk. The area forms part of the Elephant Mountains, which are contiguous with the Cardamom Mountain range to the northeast. The southern boundary of the Park is located less than one kilometer from the coastline of the Gulf of Thailand. The northern boundary forms a seven-kilometer link to Kirirom National Park, separated only by the National Highway. It is 1,075-metre high above sea level and about 11 kilometres from kampot town to the foothill and 32 kilometres from the foothill to the cloudy peak.
The Park was first accessed in 1916 and developed later as a famous altitude resort during the regime of the French Protectorate and Prince Norodom Sihanouk in the 1960s. It was abandoned during the Khmer Rouge regime in the 1970s but it served as a strategic base for Vietnamese and Khmer Rouge forces during most of the last few decades.

The range of natural habitats found within Bokor support a number of important mammal species including tigers, leopards, Asian elephants, sun bears, and gibbons, etc. A total of 223 bird species have been recorded in the park, six of which are globally significant, 13 are regionally significant, and 12 have never been seen elsewhere before. Therefore, the park was listed as one of Cambodia’s two ASEAN Heritage Parks in 2004.
