Tonle Sap Lake
The Tonle Sap Lake reaches its maximum size during August, making it one of the most fascinating times to visit this ecological wonder. As Cambodia’s largest freshwater lake, the Tonle Sap undergoes a remarkable transformation during the rainy season when the water level rises dramatically.
