    A must visit.

    We were very lucky to have Ran as our guide. He was able to bring his own personal experiences to deepen, what is already a very poignant history. The tour itself was very well organised, and we were in a small group with 6 others (who we didn't know before.) As you might expect, the tour to the Genocide Museum was emotional, with a lot of photos of the prisoners. To hear their stories and stand in the cells they were kept in was very hard but they need to be remembered. We saw the last 2 survivors of the prison, now aged 88 and 95. We have no reservations recommending this tour to you.

    Very interesting, informative tour.

    This was a very interesting, informative tour. Really enjoyed it, although it was sad and shocking too. Our guide was very knowledgeable and shared his own experiences of the time. Would recommend for sure.

    The killing fields and Genocide museum

    It was an eye opening experience to experience the Genocide Museum and the Killing Fields. Our guide was very very knowledgeable and gave us a very informative and tour. It was actually a class for me. I’m so glad I did this trip. I got some new insight. Sad history and glad I’m more educated on it now. This is a must do trip. The guide and driver are super helpful, a professional and friendly.

    A very sad but interesting tour

    100% recommended for history lovers. The tour is very explicit and graphic, but history is told exactly as it happened.

    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 $18 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 4.3 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 72 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.7/5 across 19 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Phnom Penh, and how flexible the cancellation terms are.

    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 4.3-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 7 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 4.3-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, 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.
