Cambodia Geography

Cambodia's geography centers on the Tonlé Sap, Southeast Asia's largest freshwater lake, which sits in a low central basin and dramatically expands during the wet season as the Tonlé Sap River, fed by the Mekong, reverses direction and floods the surrounding plain.

The Mekong River crosses the country from north to south before continuing into Vietnam, while the Cardamom Mountains in the southwest hold Cambodia's largest remaining rainforest and the Dângrêk Mountains form a natural escarpment along the Thai border to the north.

A relatively short coastline along the Gulf of Thailand in the south holds Cambodia's beach towns and islands, including Sihanoukville and Koh Rong.
