Tonle Sap Lake is the largest fresh water in South East Asia. It usually varies in size and depth depending on the monsoon or dry seasons. Tonle Sap is filled by water flowing from the Mekong. The lake itself is a massive resource commercially for Cambodia as it will provide more than half of its fish. It is also a massive tourist attraction with tour boats visiting every 30 minutes or so.
The lake itself boasts over 300 species of fresh water fish. It is home to snakes, crocodiles, tortoises, turtles and otters. There are more than 100 avian varieties including storks and pelicans.
The floating village has a school, basketball court and even a crocodile farm which can all be visited on the tour.
The boat tour lasts about two hours and costs twenty dollars per person. Not so good in the dry season but I can imagine it would be well better when the water is much deeper.
