About this experience
A professional English speaking 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 Rouge, lead by Pol Pot, turned the place into what became known as the killing fields, where they executed around 2.000 prisoners. 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. you could ask any question tour tour guide

Important never to forget
The guide Sem Keaksa was knowledgeable informative and kept the group moving at a nice pace … not raced yet not too long Very sad place after visiting the extermination camps in Germany and Poland the viciousness of PolPot on all esp children and babies defies belief Solemn experience that schools should teach to try and get future generations to endorse peace

Good tour
Good tour and guide Sum Cheath was very knowledgeable with excellent English. Very informative.

Excellent tour
Great tour! Chesda was knowledgeable and kept things light when appropriate for such a heavy subject. You could do the same activities alone and use the audio headphones provided at the two locations, but it was better imo to have someone explain the history and context as well, and to be able to answer questions.

Great tour
We had the killing fields and genocide museum tour, the guide was excellent, informative and guided us and give plenty of time to explore ourselves

Must do tour for anyone visiting Cambodia and with an interest in their history
This was a really interesting tour and I learned a lot. Not for the faint hearted, or for young children, as the content is very graphic and very confronting. Tour guide was very knowledgeable and answered all our questions. Would recommend for anyone wanting to learn more about Cambodia’s dark history.

Tuol Sleng Genocide Museum (S-21) and Choeung Ek Killing Fields Tour: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Phnom Penh.
How much does Tuol Sleng Genocide Museum (S-21) and Choeung Ek Killing Fields Tour cost?
+
Prices start at $19 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Phnom Penh usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Tuol Sleng Genocide Museum (S-21) and Choeung Ek Killing Fields Tour take?
+
Plan for about 4 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Phnom Penh is not rushed.
Is Tuol Sleng Genocide Museum (S-21) and Choeung Ek Killing Fields Tour worth it?
+
It holds an Outty Ranking of 88 out of 100, which we label "Exceptional". That score blends traveler sentiment (5/5 across 125 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable most highly reviewed in Phnom Penh, and how flexible the cancellation terms are.
Can I cancel or reschedule Tuol Sleng Genocide Museum (S-21) and Choeung Ek Killing Fields Tour?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Tuol Sleng Genocide Museum (S-21) and Choeung Ek Killing Fields Tour suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 4-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Tuol Sleng Genocide Museum (S-21) and Choeung Ek Killing Fields Tour?
+
Around 44 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Phnom Penh can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Phnom Penh and add a light layer if any part of the 4-hour experience runs outdoors or after sunset.
Where does Tuol Sleng Genocide Museum (S-21) and Choeung Ek Killing Fields Tour start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Phnom Penh within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Phnom Penh?
+
On Outty we rank every Phnom Penh experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Half Day Tuol Sleng S21 and Choeung Ek Killing Field Tour, The Killing Field and Toul Sleng Genocide Museum (S21) Tour, Killing field and Toul Sleng genocide museum Tour. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Phnom Penh?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Phnom Penh?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
