Boeng Tonle Chhmar

The Boeng Tonle Chhmar encompasses 145.6 square kilometers of wetlands, featuring permanent open water bodies, small waterways, and flooded forests along the Tonle Sap lake.

The site received official designation as a protected Ramsar wetland in 1999, becoming one of three such locations in Cambodia under site number 997.

Five floating villages within the protected area maintain traditional fishing practices while adapting to seasonal water level changes in the wetland ecosystem.

Guided tours through the wetland provide opportunities to observe numerous bird species, including the painted stork, black-necked stork, and spot-billed pelican.

During wet seasons, Boeng Tonle Chhmar merges completely with Tonle Sap lake, creating an extensive water system that supports two major rivers: Stoung and Chikreng.
