SPYTRAIL: Hunt for the Mole (Self-Guided Adventure Walk)
Book on Viator →Operated by SideWalks · Bookable on Viator
A spy story in your pocket beats sightseeing. SPYTRAIL: Hunt for the Mole turns central London into an interactive walking game, with questions, visual clues, and an open-ended plot where you decide if you act like the hero or the villain.
I especially love how self-guided it is. You can go any day during daylight hours, pause for a drink, and move at your own speed instead of timing your day around a group.
One possible drawback: the experience starts with your phone game access, and getting set up can take time if you need help connecting.

Key things that make SPYTRAIL fun

- A spy plot you control: your choices shape the tone as you solve the mystery
- Telegram-based, self-paced adventure: no guide, no fixed start time
- Trafalgar Square as the launch pad: a super-central place to begin and wrap up
- 5km, not a sprint: planned as an adventure walk with time for breaks
- Wheelchair and buggy access: six step-free detours are built into the route plan
Trafalgar Square to Trafalgar Square: the “2 hours” loop

This is a half-day-feeling London activity built around one simple idea: start at Trafalgar Square, follow the game prompts across central streets, and end back where you began. The route is about 5km, and the whole experience is designed for an easy-going adventure pace rather than a race.
In practice, that means the length is realistic. You’re not trying to beat the clock or force sightseeing back-to-back. The game is meant to stretch your attention as you walk, and that can be a relief in a city where people often cram too much into too little time.
If you’re the type who likes to wander but also likes direction, this setup hits a sweet spot. You get a story plus tasks, but you still choose when to slow down, take a photo, or step off-route briefly to rest.

How the Telegram game works (and what to expect on your phone)

SPYTRAIL runs inside the Telegram Messenger app. After you book, you’ll receive a unique gamecode via a message (and you cannot pull it from the Tripadvisor ticket link). Once you activate that code and begin, you get a message that sets the scene and sends you on your walk.
You’ll follow visual clues and map-based navigation. Instead of needing a signposted trail, the game acts like a guide that updates as you reach each stage.
The tools are also practical:
- /ROUTE to get guidance on what to do next
- /HINT when you feel stuck
- /SKIP to move past a problem and keep your momentum
That trio matters because it changes the whole experience. You can treat it like trivia fun, or like a puzzle hunt, or like a relaxed mystery stroll. Nobody has to decide correctly on the first try.
Your 5km route: pacing, doubts, and “spot it” moments

Because the route is self-paced, the walk rhythm is mostly up to you. You’ll be moving through London using location-based tasks, and the story is designed to create little waves of uncertainty—moments where you think, I might be wrong—followed by a payoff when something clicks.
Those “spot it” moments are the point. The game nudges you to look harder than you would on a regular walk. You’re hunting for clues with your eyes and your brain, not just your feet.
There’s also a built-in sense of flow: you keep moving from step to step until you reach the final solution. The experience is open-ended in tone (hero vs villain), but the structure stays clear: start, follow prompts, solve, finish back at Trafalgar Square.
A small but important note: snacks and transit aren’t included. So if you plan to treat this like a true two-hour block, keep water handy and consider budgeting a short rest break rather than planning a long detour meal unless you’re okay finishing early or late.
Clues, trivia, and the hero-villain choice
This isn’t just walking for walking’s sake. SPYTRAIL leans into curiosity—history-flavored trivia, light problem-solving, and the satisfaction of answering questions that unlock your next move.
What I like about the story format is the sense of agency. It’s not a “watch and listen” type of tour. You decide whether you’re playing toward the hero route or the villain route, and that changes the emotional flavor as you go.
If you enjoy puzzles or you like testing yourself as you travel, this is built for that. You’ll be mentally engaged while still getting to see London at street level, not from behind a bus window.
If you don’t love trivia, you can still do it as an adventure walk. Use /HINT to keep the game moving and avoid getting bogged down. Think of it as sightseeing with guardrails.
Using commands to keep your day on track
The game includes support commands, and they’re meant to prevent the usual puzzle-hunt frustration. If you hit a wall, you don’t have to reset your plans or guess wildly.
Here’s how to use them in a way that keeps your energy up:
- Use /HINT when you want a nudge, not a full solution.
- Use /SKIP if time matters more than completing every step.
- Use /ROUTE if you want help interpreting the next stage or staying oriented.
This is especially helpful because the experience is truly self-guided. There’s no guide standing next to you, so these commands are how you stay confident while you walk.
Also, the walk is designed for adults or teens interested in history, walking, and light problem-solving. If you’re doing this as a group with mixed ages or puzzle comfort levels, the commands help everyone participate without one person taking over.
Wheelchair and buggy access with six step-free detours
Accessibility here is more than a checkbox. The route is described as fully wheelchair and buggy accessible, using six step-free detours.
That’s important for how you plan the day. “Accessible route” doesn’t always mean “no changes.” In this case, it means you’ll likely encounter planned alternate paths that avoid steps. So if you’re pushing a stroller, using a wheelchair, or traveling with someone who prefers smooth surfaces, you should factor in that the game’s detours may slightly alter how direct the walking feels.
You’ll also be dealing with real streets. Even with step-free detours, London sidewalks and curb cuts can vary. Still, having those detours built into the adventure path is a huge practical win compared with many “find your own way” activities.
If you want a smoother finish, consider shorter breaks during the game rather than waiting until you’re already tired.
Timing it right: daylight window and a flexible start
You don’t need a time slot. The game is available Monday through Sunday from 8:00 AM to 5:00 PM within the stated date range. That flexibility is one of the best parts of this format.
I like planning it like this:
- Start when you’re fresh and can focus (morning is often easier for puzzle-solving).
- Give yourself room for a pause without panic.
- Treat the 2 hours as a guide, not a rule.
Because it’s self-paced, you can finish earlier if you’re fast with clues, or take longer if you’re careful, walking slower, or stopping to read side streets. The “adventure walk, not a race” idea is central to how you should approach it.
What you need before you go
This experience depends on your setup, so do a quick checklist first.
You need:
- A smartphone
- Telegram Messenger
- The gamecode sent after booking
You’ll also want mobile data or some way to load the game content and navigation prompts. Snacks and drinks aren’t included, so bring what you need for your own comfort.
Languages are a nice touch for international visitors: the game is available in 11 languages (English, French, German, Italian, Spanish, Portuguese, Russian, Japanese, Chinese, Korean, Arabic). If your group has mixed language comfort, you’ll likely be able to match everyone to a language they prefer.
Who should book this SPYTRAIL adventure walk
SPYTRAIL is a great fit if you want three things at once:
- a light mental challenge
- a walk that stays central
- a sightseeing day that doesn’t feel like a schedule
It’s also a smart choice for teens and mixed-age groups who enjoy games. The format makes it easy to share attention as you solve steps together, and the story keeps it from turning into pure footwork.
You might not love it as much if:
- you dislike trivia or puzzles
- you prefer a traditional guided explanation at every stop
- you want a fully guaranteed “see only famous landmarks” itinerary
Because the stops are clue-driven, the value comes from solving and discovering as you go—not from ticking off a museum list.
Value for money: what $13.59 buys you in London
At $13.59 per person for about two hours, SPYTRAIL is priced like an inexpensive “activity ticket,” not a premium guided tour. The value comes from the fact that you’re paying for the interactive game experience—story, tasks, navigation prompts—while keeping costs down.
You also avoid the typical guided-tour cost jump. No guide escort is included, no attraction entry is required, and you’re not paying for transportation inside the price.
The tradeoff is what you provide: your phone, your attention, and your time. You’ll also want to be comfortable solving tasks without someone explaining the answers. If you’re okay with that, it’s a strong deal.
Practical tips to make your spy walk go smoothly
Here are the details that matter most for a smooth day.
First, plan for setup time. Since the gamecode is manually generated and sent after booking, don’t assume you’ll have everything instantly at checkout. If you want a calm start, check your messages before you head out.
Second, keep your phone charged. You’ll be using the map navigation and clue visuals as you walk, so treat battery like an actual part of the tour.
Third, use breaks strategically. This adventure walk is designed for pauses, and it’s totally okay to step aside for water or a quick rest. If you stop for a long break, just remember it can affect how much of the game you finish in your planned window.
Finally, set expectations. This is an adventure stroll with problem-solving. It’s not a scripted lecture or a must-see list with constant external interpretation. If you want “storytelling from a guide,” this won’t replace that. If you want engaged walking and light intrigue, it fits well.
Should you book SPYTRAIL: Hunt for the Mole?
I’d book it if you want a low-cost, central London experience that keeps you active and mentally engaged without forcing you into a strict schedule. It’s a good match for puzzle lovers, curious history fans, and groups that prefer to do things at their own pace.
I’d think twice if you’re likely to get frustrated by smartphone-based gameplay, or if your group needs constant human guidance. Also, build in time for setup since the gamecode arrives via message and support tools like /HINT and /SKIP only help once you’ve started the game.
If you can handle a little uncertainty and enjoy figuring things out as you walk, SPYTRAIL is exactly the kind of day that turns a normal walk into a memorable London story.
