Koh Kong Island
Kaoh Kong [Kaôh Kŏng]
Koh Kong Island, also known locally as Kaôh Kŏng or Outer Koh Kong, is Cambodia's largest island located in the Gulf of Thailand approximately 10 kilometers south of Koh Kong town. Stretching nearly 20 kilometers north to south and 6 kilometers east to west, the island features a hilly interior with peaks reaching 360 meters and rugged rock formations that create numerous waterfalls. The island is sparsely populated with small fishing villages such as Alatang, Phumi Koh Kong, and Phumi Thmei. Covered predominantly by evergreen tropical rainforest, Koh Kong Island lies within the Cardamom Rainforest Ecozone and supports a rich variety of terrestrial wildlife including macaques, wild boar, indigenous squirrels, hornbills, and various reptiles and amphibians. Coastal mangrove forests and freshwater estuaries provide critical habitats for aquatic species, while the surrounding shallow waters harbor coral reefs and seagrass beds that sustain diverse marine fauna like whale sharks, sea turtles, dugongs, and several dolphin species including endangered Irrawaddy and Chinese white dolphins. The island's natural environment remains relatively pristine, and plans are underway to designate the surrounding waters as a marine national park, reflecting its ecological importance. Koh Kong Island's combination of natural beauty, biodiversity, and cultural simplicity makes it a unique destination for eco-tourism and nature exploration.
