About Southern Cardamom National Park

Southern Cardamom National Park is a protected area in southwestern Cambodia’s Cardamom Mountain range located in Koh Kong province, established to conserve lowland and montane rainforest. It is part of one of Southeast Asia’s largest remaining contiguous rainforest blocks.

The park protects rivers, waterfalls, primary forest and important habitat for large mammals and primates, attracting conservationists, researchers and guided ecotourism trips. Visitors encounter rainforest scenery, riverine habitats and opportunities for wildlife observation on guided excursions.

The park was created by the Cambodian government as part of broader efforts to expand formal protection across the Cardamom Mountains to reduce deforestation and poaching and to conserve key biodiversity. Management involves national authorities and conservation partners.

The park is located in Koh Kong province in southwestern Cambodia, within the Cardamom Mountains inland from the Gulf of Thailand and relatively close to the Thai border.
