    Great way to explore!

    Lovely way to explore the city. Took us to some nicer areas we would not have visited. Learned a little of the history as we went 🙂

    Response from the operator: Thats so great to hear. Thanks for joining us. We would be happy to welcome you to play again in another city! :)

    Loving the hunt for answers from the past.

    We immediately realized that we were not good at reading maps. However the staff were always ready by phone to help us figure out where we were and how to help us. I would recommend this experience to anyone. It would be great for families.

    So much fun.

    Was much fun. Jewish district, part of the puzzles done with the red sunglasses. Good mix of puzzles. Gpt cannot solve them (yet).

    Learn the history in a fun way!

    Amazing way of exploring the city! I love the level of the difficulty of mysteries and also the story based on the actual historical facts. I learned about the shockingly horrible situation at the time of the World War Ⅱand how brave people acted which was totally impressing. Definitely recommended! I would like to try other mysteries in Amsterdam and also other cities in the near future.

    Operation 45: An Adventure in Diamonds: questions travelers ask

    Practical detail on this experience, plus the wider planning questions for Amsterdam.

    How much does Operation 45: An Adventure in Diamonds cost?

    +

    Prices start at $29 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Amsterdam usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.

    How long does Operation 45: An Adventure in Diamonds take?

    +

    Plan for about 2 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 Amsterdam is not rushed.

    Is Operation 45: An Adventure in Diamonds worth it?

    +

    It holds an Outty Ranking of 72 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.9/5 across 38 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Amsterdam, and how flexible the cancellation terms are.

    Can I cancel or reschedule Operation 45: An Adventure in Diamonds?

    +

    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 Operation 45: An Adventure in Diamonds suitable for kids and families?

    +

    Yes, all ages are welcome. Families should still weigh the 2-hour running time, and strollers are easier on the earlier, quieter departures.

    How far in advance should I book Operation 45: An Adventure in Diamonds?

    +

    Around 13 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 Amsterdam 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 Amsterdam and add a light layer if any part of the 2-hour experience runs outdoors or after sunset.

    Where does Operation 45: An Adventure in Diamonds 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 Amsterdam 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 Amsterdam?

    +

    On Outty we rank every Amsterdam experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Amsterdam Food and Cultural Tour with 10 Tastings, Amsterdam Canal Cruise with Local Guide and Small Group, Amsterdam 90 minutes Canal Cruise with bar and snacks on board.. 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 Amsterdam?

    +

    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 Amsterdam?

    +

    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.

    What is included in Operation 45: An Adventure in Diamonds?

    +

    Included: You will be given the game bag with all the needed parts to play. Always check the voucher for the final list before you travel.

    Where is the meeting point for Operation 45: An Adventure in Diamonds?

    +

    Just a short walk from Central Station or Dam Square Hotel pickup is not included, so plan your own transport and arrive 15 minutes early.

    Will I get instant confirmation and a mobile ticket for Operation 45: An Adventure in Diamonds?

    +

    Confirmation is sent by the operator after booking, usually within 48 hours; if it is not confirmed you are not charged. Mobile tickets are accepted, so you can show the voucher on your phone.

    Is Operation 45: An Adventure in Diamonds wheelchair or stroller accessible?

    +

    The operator notes: Wheelchair accessible; Infants and small children can ride in a pram or stroller; and Transportation options are wheelchair accessible. If accessibility is critical, contact the operator after booking to confirm arrangements for your date.

    What happens to Operation 45: An Adventure in Diamonds if the weather is bad?

    +

    This experience depends on good weather. If it is canceled because of poor weather, you are offered a different date or a full refund.

    What do travelers say about Operation 45: An Adventure in Diamonds?

    +

    Across 38 reviews averaging 4.9 out of 5, recurring themes include knowledge and storytelling, good for families. Reviewers describe the commentary as informative rather than scripted.
