Along with the killing fields I believe this needs to be done to appreciate the very recent history of this wonderful country but I just feel it could be done better. Compared to the killing fields, the information provided and general displays could be improved to enhance your learning experience. But even in its current state it is still very worthwhile.
BEWARE: we went from here to the killing fields & had our bag stolen from our Tuk Tuk en-route. This appears to be a favourite spot for this as there were several other reportings at the same time. Please keep your bags close & secure on this trip.
