Not sure what else I can say, just go see it, ideally after the Tuol Sleng Museum as they tell the whole story together. Get the audioguide to get the entire story. It is very well made and tells a very moving story. There were some folks with an actual guide and I felt the audioguide told more. Of course, I am sure there are all sorts of quides, but just so you know. It hits quite hard to also see the places after reading about them. The nature around can help you clear your mind. I just took a long walk and thought. As for getting there, just any tutktuk driver will be happy to take you, wait for you and come back.

Part of me says this shouldn't be a tourist destination, but at the same time we must all learn what went on in this country in the past. It's pretty harrowing in places and not the place for taking pictures. Just wander quietly around the graves and contemplate what's going on in the world at the moment.

This place is so sad. Seeing what was done to the Cambodian people is heartbreaking. We saw the film first and then our guide took us around the grounds and to the stupa. We saw lots of people with headsets so if you don’t have a guide that would be a good option. Walking around the site and seeing the mass graves and bones is very sobering.

Whilst I remember seeing news items and reading reports about the horrors of this period in Cambodia’s recent history, visiting one of the killing fields to have been discovered around Phnom Penh was a very moving experience. The similarities to the holocaust atrocities inflicted by the Nazi regime on Jews and others, was only too apparent but the various means of execution seemed even more brutal in Cambodia with our guide explaining that this was to save bullets. It was shocking to hear that many of those responsible have not been punished and some even hold senior posts in the community. A very moving experience

Also known as the killing field, this is one of more than 300 sites in Cambodia where the Khmer Rouge killed and buried masses of people. We chose to do it on our own with an audio guide because the guides talking disturbed the reverence of the place. It is not an easy place to visit, but definitely worth going. The audio guide was really good, mixing stories with the history. We loved that there were a lot of places to sit in the shade to listen to the recording or just contemplate the enormity of what happened here.

Try and avoid the tour groups and walk round at your own pace listening to the audio guide, visualising and contemplating what once happened here. It is a story of a genocidal regime and an important part of recent history, not unique to Cambodia, that needs to be understood if the world is ever going to become a better place. If you have the opportunity a visit here should definitely be on your list and I would say gives a better understanding of events than the interrogation centre at S21. The central stupa is unique as a memorial to the dead.

We visited here as part of our organised trip and had a local guide with us. We entered and our guide took us around and showed us the earth with some of the fragments of clothing is being revealed, the mass graves where bones were excavated etc. It's all quite hard to hear and harrowing, but has to be seen to be understood and rightly remembered for being utterly heartbreaking.

Impressive experience. A must-do when visiting Cambodia. Tip 1: I would recommend first visiting this prison museum before heading out to visit the Killing fields. This provides a better chronological explanation. Tip 2: There really is no need to book an organised tour. Just take any tuk tuk to easily get there and back.

As others have said, audio guide is worth it though there is small information signs. The route can be a little disconnected but they’ve done an amazing job of preserving this heartbreaking place. Wasn’t too crowded and eerily quiet - a place to reflect, be grateful, gain perspective and hope it never happens again.
