The Killing Field and Toul Sleng Genocide Tour
It was a very memorable trip. We got to hear and see about the political affairs of Cambodian history. It is a cruel and very emotional journey. Special thanks to our guide Reaksa Sem as he did an amazing job guiding us.

Heavy, but Necessary
Heavy, but something on my bucket list that had to be checked off! The guide was excellent! His command of English was very good and his knowledge of the history of the Pol Pot era was superb!

Outstanding History Lesson
I had the privilege of participating in the Killing Fields and Tuol Sleng Genocide Museum (S-21) tour, led by Reaksa Sem, and I cannot say enough about the outstanding job he did. Reaksa is extremely knowledgeable and well-educated about the history of the Cambodian people and their experiences under the Khmer Rouge. The tour itself was deeply emotional and, at times, difficult to process. Despite the heartbreaking nature of the history being presented, Reaksa handled the tour with great professionalism, compassion, and sensitivity. He conveyed the tragic and painful information in a clear, respectful, and thoughtful manner, while also providing important historical context that helped me better understand what the Cambodian people endured. I am grateful for the opportunity to have experienced this tour and to have learned more about Cambodia’s history. Reaksa’s knowledge and professionalism made a profound impact on me, and I would highly recommend this tour to anyone who wants to gain a deeper understanding of Cambodia’s past and the resilience of its people.

Why this scores 93
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
The Killing Field and Toul Sleng Genocide Museum (S21) Tour: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Phnom Penh.
How much does The Killing Field and Toul Sleng Genocide Museum (S21) 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 The Killing Field and Toul Sleng Genocide Museum (S21) 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 The Killing Field and Toul Sleng Genocide Museum (S21) Tour worth it?
+
It holds an Outty Ranking of 93 out of 100, which we label "90+ Club". That score blends traveler sentiment (4.9/5 across 2,216 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable most popular in Phnom Penh, and how flexible the cancellation terms are. Scoring 90 or above puts it in the Outty 90+ Club, the top tier of everything we rank.
Can I cancel or reschedule The Killing Field and Toul Sleng Genocide Museum (S21) 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 The Killing Field and Toul Sleng Genocide Museum (S21) 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 The Killing Field and Toul Sleng Genocide Museum (S21) Tour?
+
Around 776 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 The Killing Field and Toul Sleng Genocide Museum (S21) 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, Killing field and Toul Sleng genocide museum Tour, Visit 11 Places in One Day including S21 & Killing Field. 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.
