Choeung Ek Genocidal Center
Your tour guide will pick you up from your hotel and drive you to the killing fields of Choeung Ek Genocide Center – 9 miles away south of Phnom Penh. The infamous killing fields have a bloody history. Once an orchard and a Chinese cemetery, the Khmer Rogue, lead by Pol Pot, turned the place into what became known as the killing fields, where they executed around 20.000 victim. Over three years, they massacred and buried 2.5 million people. After remembering the dead, return to Phnom Penh to visit Tuol Sleng Genocide Museum (S21). Meaning hill of the poisonous trees, Pol Pot turned a once popular high school into a high security prison. 20,000 people were imprisoned there, many of whom were tortured for information. Today it serves as a museum and a reminder of darker days. Your guide will return you to your hotel or guesthouse.
Tuol Sleng Genocide Museum
The most notorious of the 189 known interrogation centers in Cambodia was S-21, housed in a former school and now called Tuol Sleng for the hill on which it stands. Between 14,000 and 17,000 prisoners were detained, tortured there, often in primitive brick cells built in former classrooms.

After initial issues with communication, not well explained pick up details and instruction, and having to end up walking to the pick up car, holding others up. Excellent eye opener on the atrocities of the Cambodian Khmer Rouge and Pol Pot regime, killing millions of their own people. A terrible period for humanity not so long ago. Expertly explained by our guide who lived the experience and have a heartfelt guidance to the time. Truly gives you perspective and appreciate others lived experiences. Thankyou

We went to the Killing fields and S21 with our guide Rouan (apologies if I misspelt his name). Rouan was amazing in sharing all the history leading up to Pol Pot and then taking us through that awful time, including how it affected his own family. The tour was very emotional but we felt it was important to understand what the people of Cambodia went through so recently. It is a testimony to the people here that the museums exist and that people want to share their histories to help stop these awful things happening again. We also met Chum Mey at the end of the tour - a 95 year old survivor of S21 who now dedicates his life to sharing his experiences of what happened. There was no pressure to buy his book but I was happy to help support Chum Mey as our guide explained there is no social security to help look after him and the 10$ his book cost is used 50% to support Chum Mey and 50% to support other survivors. Although a tough day in terms of the horrors you see, I recommend the tour so we can all help spread what we learn and remember the poor victims.

Worth a visit. Would have liked longer to wander around the killing fields after the guided tour bit. Genocide museum made more stark by meeting 2 of survivors.

We visited this on our last day in Cambodia, and it was an incredibly moving experience. Throughout our trip, we’d heard stories from our guides in Siem Reap and the locals, but seeing and experiencing this firsthand was deeply sobering. At times, we felt truly overwhelmed and found it hard to process the emotions. Our guide, who had personally lived through those years, shared invaluable insights and stories that offered a powerful and comprehensive perspective. I would strongly recommend that anyone visiting this beautiful country take the time to explore this part of its history. It’s a story that deserves to be seen, heard, and remembered so that history is preserved, and never repeated.

Our guide was very good and we got honest answers. This tour makes a big mark. Terrible to hear about torture, but appreciate that they are doing this, so that we can all prevent it from happening again.

Our tour guide Neng picked us up from hotel and we then proceeded to the Killing Fields and S21 Museum. It was only My partner and I on the tour. It was a very harrowing half day experience as you visually saw the devastation, complete disregard for human life and evil under the Pol Pot regime. 100% recommend to anyone attending Cambodia 🇰🇭 to learn about how the country is rebuilding and restoring peace. Also recommend our tour guide who was so knowledgeable and kind! we asked so many questions and he knew the answers and MORE to all of them.
