One of the best days I had in Cambodia was a day trip I made to Kompong Phhluk, a floating / stilt village about 40 minutes drive outside of Siem Reap.

Built in the flood plain of the Tonle Sap the houses here tower on stilts as high as 10 meters. In wet season the stilts are hidden and water laps at the floorboards.

I booked the trip through Beyond Unique Escapes (based in Siem Reap) and they were brilliant - our guide was really knowledgeable and friendly and we got to see how all the people who live in this village live their lives.

Can't recommend it enough, and you get a packed lunch included - sandwiches wrapped in banana leaves!
