A fabulous experience!
This was a fascinating and entertaining experience. Put together with real care, imagination and insight. A fabulous exposure to history that is both invisible and in plain sight.
Response from the operator: Thanks very much. So glad you enjoyed it.

Thoroughly Enjoyable and Enlightening
This is an excellent tour. It was very easy to navigate and I learned so much. I thoroughly enjoyed the very central route. Highly recommended. This was my second and again I am looking forward to trying another.
Response from the operator: Thanks very much! Really glad you enjoyed it. Best wishes, Alex from SideWalks

Setting it up was a...
Setting it up was a hassle. Had to connect with someone to walk us through it. That took more than 1/2 hour and lots of frustration! But the experience itself was lots of fun. Our 3 teenaged grandchildren enjoyed it and we saw places we would have missed otherwise. Only finished 25% of game since we stopped for lunch and had a participant in a wheelchair.
Response from the operator: Thank you very much!

Really fun adventure, finding clues and discovering hidden bits of London
Fantastic! Had a lovely couple of hours discovering and learning about bits of London you would otherwise just walk past without noticing. Amazing how many central locations were Cold War spy bases or dead drop sites. We even managed to decode the message at the end. The clues were fun and not too difficult (and you can get hints and help at any stage), and it was great to be able to stop for a drink or bite to eat wherever you want. Really good value - and great exercise too! Can't wait to try another one - Sherlock Holmes Murder trail next!
Response from the operator: Thanks very much!

Why this scores 63
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
SPYTRAIL: Hunt for the Mole (Self-Guided Adventure Walk): questions travelers ask
Practical detail on this experience, plus the wider planning questions for London.
How much does SPYTRAIL: Hunt for the Mole (Self-Guided Adventure Walk) cost?
+
Prices start at $10 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in London usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does SPYTRAIL: Hunt for the Mole (Self-Guided Adventure Walk) 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 London is not rushed.
Is SPYTRAIL: Hunt for the Mole (Self-Guided Adventure Walk) worth it?
+
It holds an Outty Ranking of 63 out of 100, which we label "Solid Choice". That score blends traveler sentiment (4.8/5 across 4 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in London, and how flexible the cancellation terms are.
Can I cancel or reschedule SPYTRAIL: Hunt for the Mole (Self-Guided Adventure Walk)?
+
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 SPYTRAIL: Hunt for the Mole (Self-Guided Adventure Walk) 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 SPYTRAIL: Hunt for the Mole (Self-Guided Adventure Walk)?
+
Around 1 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 London 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 London and add a light layer if any part of the 2-hour experience runs outdoors or after sunset.
Where does SPYTRAIL: Hunt for the Mole (Self-Guided Adventure Walk) 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 London 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 London?
+
London's best attractions split cleanly: the museums are free and need no booking, so the paid market is about views, theatre and getting out of the city for a day. That makes value scoring unusually important here, and the Outty Ranking penalises anything charging premium prices for access you could get for nothing. On Outty we rank every London experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Soho Music & Historic Pubs Tour, London Small Group Tour of Historical Pubs, The Great British Rock and Roll Walking 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 London?
+
May to September for long evenings, December for the Christmas markets. 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 London?
+
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.
