The Tonle Sap is a combined river & lake in Cambodia. Its the largest freshwater lake in South-East Asia and is a major ecological hotspot which was designated as a UNESCO biosphere in 1997.
If you are interested in reading more about the Tonle Sap, you may like to read the Wikipedia article.
However if you just want to see the pictures of life along the river from our day trip (admittedly a few years back) travelling from Battambang to Siem Reap, just scroll down.

My 7-yr-old tapped the like. =) He studied SE Asian geography last year so I shared the post. Amazing how people live!
Thanks, glad you and he liked it 🙂
Fascinating trip and wonderful photos!
It was very cool 🙂 I love visiting places that are so different to where I live.
