Tonle Sap - The Unique Lake in the Heart of Mekong

Having an excursion to the Kingdom of Wonder is a remarkable journey to not only discover the ancient world with Angkor complex but also enjoy the biodiversity in Tonle Sap Lake. It’s good chance to get new experiences with nature when you pay a visit to Tonle Sap Lake - the largest freshwater lake in Southest Asia.


Like other destination, the name of the lake also reveals one of its features. In Khmer, tonle literally means large river and sap is fresh or not salty. Thus, Tonle Sap can be understood as the large freshwater river. In Cambodia, the Tonle Sap Lake which is well-known as Great Lake is the combination of lake and river system.

The dimension of the lake changes when the flow of water changes, which can be seen clearly in two different seasons (the wet and the dry season). The wet season ranges from June to October. It’s time the huge amount of water flowing backward from Tonle Sap River fills the lake and brings alluvial and the rich biodiversity to this unique ecological hotspot. This is partly explained by the annual phenomenon. The snow in the Himalaya Mountains melting and flowing into the Mekong River will cause the Tonle Sap river to reverse its flow and run into the lake. This makes the size of the lake expand more than five-fold with surrounding floodplains and flooded forest.

This area plays an important role in making home for several kinds of birds, fish spawning and breeding babies as well as many other mammals such as turtles, snakes and crocodiles. In the dry season (from November to May), the lake is fairly small since the water will drain into the Tonle Sap river to flow to Mekong river. Thanks to the diverse eco-system, in1997 Tonle Sap Lake was designated as UNESCO biosphere.


The Great Lake where has natural resources such a large amount of fish and wetland is an ideal place for residents. The majority of people living around the lake earn their living from fishing and agriculture. Thus, there’s no doubt that visitors can find several stilt houses near the waterway or boat houses on the lake.
