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.

This is a trip that one shouldn't have to take and although difficult and heartbreaking it is essential. Our guide Makara was so knowledgeable, not only about the killing fields but also about the history of Cambodia. We came away with a better comprehension of the country.

We were very lucky and were the only people on this tour, so had our guide, Darian, all to ourselves. He was very knowledgeable, having had first hand experience of the fall out from the time of the Killing Fields.

This was a really well run tour. Our guide was really friendly and knowledgeable, and shared so much information about Cambodia’s history, the years leading up to the genocide as well as the aftermath. He also shared some of his personal experiences with us. We took our time walking through both the killing fields and the S21 prison, and got so much information. Tour Agency was very communicative via WhatsApp for pickup location and times. Would absolutely recommend this tour for anyone visiting Cambodia.

Excellent trip, we were collected promptly from our hotel by Sam our guide. Starting at S21, Sam provided a clear overview of the history and circumstances that led to the KR regime and subsequent genocide. He answered any questions and allowed time for reflection. Air conditioned minibus, excellent trip and I highly recommend and Thank You Sam 🙏🏼🙏🏼

I had a great tour with our guide Rand (not sure of the spelling). The picked me up on time and we were only 3 total in the van, I call that a VIP tour. Rand was very interesting to listen to since he lived through the whole Khmere Rouge era. I was wondering how come he remembered all those dates, well, he lived it. He took us to Killing Field and this was really important for me since I visited S-21 prison the previous day. It was so interesting that I went back to visit the prison again but this time I had the opportunity to ask question to my guide. I was there the day before but did the tour solo with the audio option. A very good day !!! Steve

Very important visit that gave us deeper insight on the horrors of the Khmer Rouge regime. Very colorful descriptions in the audio guides that are available in many languages, even ours, Swedish. The place is pedagogical and flexible so you can stroll around in your own pace and order. We were 4 persons and choose to take a taxi from our hotel to the museum (S-21). and after that directly to Killing fields at Choeung Ek. Had lunch at a restaurant right across the entrance of Choeung Ek. Strongly recommended

Mr Chamrouen is the best guide for your visit. Not only you get a very knowledgeable and good English speaker guide but also you get a first hand experience from a person who lived himself in that horrible time. In a place of sadness, Mr Chamrouen makes your visit the most amazing ever! Well recommended! Our group loved it.

This was a deeply emotional guided tour and a first person experience narrative of the terrible events of Pol Pot’s regime.
