The other name of this place is Killing fields. This is not the easiest place to visit. Museum of the genocide of innocent people in Cambodia. A reminder of what human ignorance can do and we know that such places still exist in other countries. Find enough time to visit this Museum. It is better to take 2.5-3 hours to walk slowly and listen to the history of this place through the audio guide and to honor the memory of people who never left the walls of this camp.
