    Fabulous tour guide

    An amazing amount of history was explaining in great detail by our guide Reaksa Sem. If you want to know about the 1970s horrendous experience by the Cambodian people, do this tour. i've read about it, I've heard about it But it's hard to grasp the severity of the genocide until you have been at these places and see the pictures and the prison and the killing fields.

    Excellent tour, very knowledgeable guide

    A fascinating, and at times harrowing, tour. The guide Cheath was extremely knowledgeable and personable, and gave us lots of information about the history and politics of Cambodia as well as the Khmer Rouge period. Don't miss this tour when you're in Phnom Penh!

    Expert depth , passion and knowledge

    Sum Cheath was exceptionally knowledgeable on our tour to the killing fields and S-21. He provided a detailed background of the historical events of the atrocities in Cambodia. His passion and depth of knowledge was appreciated on this very painful topic. The tour is highly recommended for anyone visiting Cambodia.

    Must do tour

    Must do tour to enlighten more people and preserve the history. Tour guide Sum Cheath was excellent - so passionate in sharing the horror but in a compassionate way. The bus was a little past its due date but the driver was excellent. I hope the guardians of the sites make a more conscious effort to maintain the sites and keep it clean and tidier. Please be respectful and follow the dress code.

    Good tour with Cheath as a great guide.

    The tour was excellently organised and Cheath was a great guide. His knowledge was exceptional and his descriptions of the trip were detailed and honest. There was also so much passion in his voice regarding the subject matter and you really felt part of the tragic history that you were witnessing. Very moving and at times harrowing tour but a definite must see to remind ourselves that this horror must never be repeated and to pay our respects to the victims.

    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 2,259 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 791 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?

    +

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.
