Tonle Sap Lake

Ranging from 1000 square miles in dry season to an amazing 6,700 square miles in wet season, Tonlé Sap Lake is the largest freshwater lake in SE Asia.
Boat trips are available to visit the floating villages and other lake inhabitants, as well as offering an alternative to road travel to Battambang and Phnom Penh.
Prek Toal and Bird Sanctuary
The boat trip to Prek Toal takes about two hours from Chong Kneas boat dock to the research station. Here you will find information on the area's flora and fauna.
There is also some basic overnight accommodation if you want to stay the night to take full advantage of the sunset and early morning viewing hours.
The entrance fee for bird watching for 2 people costs $25 each, for 3 or more it costs $20 per person including a guided boat tour to the bird sanctuary. Entrance fees are used to help promote responsible tourism in Cambodia, and contribute to the conservation of the area especially the education of children and locals about the importance of the birds and the unique flooded forest environment.
The Biosphere covers 31,282 hectares at the northwest tip of the Tonlé Sap Lake and plays host to species including Greater and Lesser Adjuncts, Black-headed Ibis, Painted Stork, Milky Stork, Spot-billed Pelican, Grey-Headed Fish Eagle and many more species.
The best time to explore is the dry season between December and May when flocks of migratory birds congregate at Prek Toal.
