Tonlé Sap

Tonlé Sap, located in Cambodia near Siem Reap, is a vast freshwater lake spanning 1,000 square miles (2,600 square kilometers), making it the largest in Southeast Asia. Recognized as a UNESCO biosphere, the lake’s unique natural features include a remarkable seasonal transformation. Twice a year, the flow of water reverses, causing the lake to expand and contract with the changing seasons. Visitors can explore this dynamic ecosystem, observing the diverse wildlife and traditional floating villages that adapt to the fluctuating water levels.
