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.

Very worthwhile but sobering tour of the turmoil and genocide in Cambodia, perpetrated by Pol Pot. Our excellent guide Ran, told the story from somebody who grew up in those dark days. Highly recommend this tour to understand how the despot Pol Pot ruled in Cambodia in the late 70’s .

The pickup was convenient and in an air conditioned van. The tour guide Nin was very knowledgeable, but more notably she was extremely helpful when I experienced symptoms of heat exhaustion, bringing water and finding me air conditioning. (Be advised this tour is entirely open air with some shade.)

We booked a tour thru Viator for 15 people was an easy process and our tour guide and bus arrived on time and Mr Ruoen was our guide. He was excellent he made the tour, very informative and emotional at the same time he told us the story from his heart and from his experiences. Its a tour not for the faint hearted but something visitors must do highly recommend the tour and Mr Ruoen.

The Tour provides plenty of time at both the Killing Fields and Genocide Prison. Our tour guide was very knowledgeable and able to provide personal reflection from his own families suffering. Our driver DaRa couldn’t have been more helpful with regular bottles of cold water. Very educational, emotional and good value. Take cash for the entrance fees.

We had an excellent tour today with Ran as our guide. He gave us a lot of history and context about the regime both before and during our visits to both the killing field and the genocide museum, as well as spoke about his personal experiences. It is quite a heavy and sobering experience but important to understand and learn from.

This was an incredible tour! The tour guide was so friendly, knowledgeable and engaging. He did a great job telling the history of Pol Pot and including his own history as well. This was a must see experience, I am very grateful to the tour guide and driver. Very comfortable bus with AC and cold water available.

I had such an incredible experience with this tour! Our guide and driver were amazing. Our guide was so kind and so informative, I would absolutely recommend this tour to anyone visiting Phnom Penh. There was always water available and the guides own story telling was amazing and touching.

What an amazing four hours learning about what happened at these two sites and how the political story allowed it to happen. It was all made real to us by our guide Nin who, with very good English, spoke slowly and clearly and gradually revealed the horrors. We felt that although we heard accounts of a horrifying nature it is important that these events are known about to prevent them happening in the future. The Cambodian people have made the Killing Fields and S21 into tranquil and respectful places. Thank you Nin and your driver for making us understand.

It was an emotional and insightful experience. Net was very informative and shared experiences from his own life and his parents, who lived through these times.

This tour was educational but sobering. Our guide, Ram, told the story of the terrible events in an interesting and measured way. We felt he presented the facts and the emotion they cause in an appropriate way. We’d like to thank Ram and our driver, Dara, for showing us this important piece of history.
