What you'll see and do
Centraal Station
If you're taking either the public train or the tram lines throughout this stunning city, chances are pretty good that you'll pass through here. Being located in the heart of town, Amsterdam Centraal Station is a neo-Renaissance rail station that was designed by P.J.H. Cuypers and completed in 1889. It became the benchmark for clean, state-of-the-art public transport and above that, a beautiful historic building housing more than just an impressive transport hub! Here you will find lots of shops and places to grab a bite, so get energized as you have a long and fun way ahead with Questo! Solve a challenge here based on your immediate surroundings in order to advance to the next location.

Weeping Tower
Welcome to The Schreierstoren or The Weeping Tower! Don’t worry, you have nothing to cry about! Initially built as a defense tower in the 15th century, this place reminiscent of the medieval city of Amsterdam discloses some of the most fascinating stories. Its name comes from the fact that women wept there for their husbands, who would often leave from that port to go to war or to fishing. Either way, they were unsure if they would see their beloved ones again, so this place emotionally remained in history as a “departing spot”. But on a more optimistic note, the Weeping Tower is also famous for being the location from which Henry Hudson set sail on his journey to Northern America that lead to the discovery of the Manhattan Island. Nowadays, you can enjoy a coffee here in a nautical bookstore while searching for the next clue that Questo has prepared for you. Look around! Who knows, maybe you are sitting next to it.

Montelbaanstoren
It’s the year 1517 and Amsterdam is being under siege! Soldiers are coming your way and you need to find shelter as soon as possible so you can save your life. Where should you go? That’s right, the Montelbaanstoren is the place for you: a historic tower on Amsterdam’s Oude Schans canal built as part of the “Walls of Amsterdam” to defend the eastern side of the harbour from potential attacks. Whether you are cruising down the famous canals of Amsterdam or walking around this place, you will certainly spot this magnificent 48m-high structure. Mysteries and questions surround this place, but you have to answer only one of them to unlock its story and move on the next.

Red Light District
Now, you reached the most iconic place in the world where you can drive or walk on the red light! And I am not referring to the traffic lights, but to the best known red-light district from Amsterdam: De Wallen. Probably, you have heard about this neighbourhood before and to be honest, everything you have heard is mostly true. From brothels to sex shops to museums, the Amsterdam Red Light District has it all. Amsterdam prides itself, and rightly so, on its wholly liberal and tolerant attitude, embracing the fact that people may be into prostitution, soft drugs and pornography. So instead of criminalizing everything, they enjoy the honesty of it all. However, you don’t have to be a fanatic to go there, you will be surprised to find a very friendly atmosphere and not as dangerous as it used to be. Once here, you can spend as much time as you wish, but don’t forget that Questo has other places in store for you!

Nieuwmarkt
Nieuwmarkt is just around the corner! Located right in the center of Amsterdam, this square houses lots of cafes and restaurants, where you can feel like a local, this being a centre for commerce and socialising in Amsterdam since the 17th century. During WW2 the square was used by the Nazis as a collection point for the Jews that were unfortunate enough to be sent to the concentration camps. The Nieuwmarkt is dominated by the presence of a mysterious building known as De Waag, which was a major entry point to the city before the old city walls were destroyed. Filled with historical significance, here Rembrandt painted The Anatomy Lesson of Dr. Nicolaes Tulp. And that’s not all. Want to know more? Search around you for the challenge to unlock the full story.

Oude Kerk
You are probably thinking right now how come in the middle of the Red-light District you can find a majestic church, namely the Oude Kerk or the Old Church. Whether it is for confessions or not, we can’t ignore its big and monumental architecture. The Oude Kerk is the oldest building from Amsterdam and for centuries was the most important church in the city. Nowadays, it is not a regular church anymore. Here, the art and music mingle together to create an unique experience. In 2016 the building also became an official museum, inviting contemporary artists to exhibit and interact with the historic space. If you are curious to know more about this peculiar church, then pray to God to reveal the hidden clues to you!

Our Lord in the Attic Museum Ons' Lieve Heer op Solder
By now, we have learnt that Amsterdam is the city that likes to stand out from the crowd by being surprisingly nonconformist. If you thought you have seen it all, then get ready because the final destination is not one to miss. The Museum Ons'Lieve Heer Op Solder, which translates to “Our Lord in the Attic”, is a 17th-century house with a top floor converted into a Catholic church. This 3-in-1 combination of canal house, church and museum is tucked away in the heart of Amsterdam’s inner city and introduces you to the atmosphere of the unique Dutch Golden Age. Simbolizing the openmindedness of Amsterdam that stems from the past tolerance to freedom of religion, this boutique museum lures travellers inside for a bit of history. If you find the hidden clue (in the attic or not), then you can call yourself a true Questo explorer!

5* Treasure Tour
This tour was really good fun and took us to places we hadn't seen during our weekend in Amsterdam. Very interesting facts along with the fun of being on a Treasure Tour. Easy to navigate.
Response from the operator: Hello there! Thank you for sharing your feedback. It brings us joy to know that you had a great time exploring the city through our game. We hope you can share your experience to your friends and family. :)

Interessing experience in a town
Interesting walk through narrow streets of old Amsterdam, some of the searched points were difficult to find. The route on the map was helpful. For the future you should absolutely remark, that the way leads a short time through the "redlight district"!!! We made the tour with our grand-children and they were very astonishes and horrified about the "ladies" in the windows.
Response from the operator: Thank you so much for sharing your experience of our walk through the narrow streets of old Amsterdam. Your feedback means a lot to us, and we want you to know that we're genuinely interested in addressing any concerns you may have. We're really sorry if the brief passage through the "red-light district" during the tour came as a surprise, especially with your grand-children. We never intended to cause any discomfort. Your family's experience is important to us, and we take your feedback to heart. We're constantly working to improve our games and create enjoyable experiences for everyone. Your feedback helps us understand where we can make adjustments and ensure that future participants, including families, have a fantastic time. See you at the next adventure with Questo :)!

Why this scores 74
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Amsterdam Treasure Mystery: The Sailor's Lost Diamonds: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Amsterdam.
How much does Amsterdam Treasure Mystery: The Sailor's Lost Diamonds cost?
+
Prices start at $7 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 Amsterdam Treasure Mystery: The Sailor's Lost Diamonds take?
+
Plan for about 1.5 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 Amsterdam Treasure Mystery: The Sailor's Lost Diamonds worth it?
+
It holds an Outty Ranking of 74 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.9/5 across 40 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 Amsterdam Treasure Mystery: The Sailor's Lost 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 Amsterdam Treasure Mystery: The Sailor's Lost Diamonds suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 1.5-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Amsterdam Treasure Mystery: The Sailor's Lost Diamonds?
+
Around 14 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 1.5-hour experience runs outdoors or after sunset.
Where does Amsterdam Treasure Mystery: The Sailor's Lost 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 Canal Cruise with Local Guide and Small Group, Guided Bike Tour of Amsterdam's Highlights & Hidden Gems, Amsterdam: Luxury Canal Cruise including Cocktails & Snacks. 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.
