Discover London's hidden gems with this smartphone treasure hunt through the City of London, combining fun clues, history, and optional pub breaks.

This review looks at the Immersive Treasure Hunt Adventure in London, a self-guided activity designed to turn sightseeing into a fun puzzle-solving experience. Instead of traditional tours with guides and buses, this adventure invites you to explore the City of London at your own pace, using clues sent directly to your mobile phone. With a price tag of just over $40 for two people, it offers an affordable way to discover some of London’s lesser-known sights while enjoying a bit of friendly competition.
What really appeals about this experience is the freedom it offers. You can start near St Paul’s Cathedral, work your way through historic streets, uncover Roman ruins, and stop for optional pub breaks along the way. A particular highlight is the opportunity to discover hidden corners of the City that often escape the usual tourist routes. However, since it’s a self-led activity, it requires some walking and a basic comfort level with navigating using your phone. Travelers who enjoy solving puzzles, exploring at their own pace, and mixing history with a bit of light-hearted fun will find this a great fit.
One potential consideration is that street closures or construction may sometimes disrupt the route—something one reviewer noted. It’s wise to be prepared for possible detours or delays, especially if you’re on a tight schedule. This tour is best suited for adventurous travelers, small groups or couples, and those looking to add some hands-on, interactive fun to their city break.

The adventure begins right outside St Paul’s Cathedral, a stunning landmark and a fitting starting point for this urban treasure quest. Once you check in, you’ll receive a trail of riddles through either the Telegram app (recommended) or SMS, guiding you through about 4.7 km of London’s historic streets. The clues are designed to push you to think and look around, revealing stories and sights you might otherwise overlook.
The two-and-a-half-hour duration is flexible, but most groups find themselves immersed for that length of time, especially if they pause at pub breaks or take their time absorbing each stop. The trail includes 15 clues, each leading you to a new location—some off the usual tourist radar, like a Roman amphitheatre and a Victorian market—giving you a layered appreciation of London’s past.
Roman Amphitheatre & The Original Settlement
One of the highlights is discovering remnants of London’s Roman origins. The clues guide you to a Roman amphitheatre, a rare piece of history tucked away near the modern city. It’s a chance to connect with London’s ancient roots without the crowds of the more famous historical sites.
Cozy Inn and Victorian Market
Midway, there’s a stop at a cosy pub-like inn, ideal for warming up and recharging. The atmosphere is warm, and you might find yourself enjoying the local ambiance, as one reviewer noted. Continuing onwards, you’ll pass through a Victorian market, an authentic slice of London’s trading history. These less-visited spots give a sense of how London has evolved from its Roman beginnings to a bustling Victorian hub.
Ruins and a Top-Notch Pub
As you descend into “magical ruins”—perhaps remnants of old structures—you’ll feel a sense of discovery. The trail concludes at a well-regarded pub, where you can relax, compare answers, or grab a cold drink. The pub options are outside the activity, so drinks are additional costs, but they offer an excellent way to wrap up the adventure on a social note.
Each clue is designed to be solvable, with hints available if needed. If you get lost, messaging “Lost” will provide a detailed route, which is helpful since the activity is self-led. People who enjoy puzzle-solving, or who are comfortable with some light walking and navigation, will find this format engaging and non-intimidating.
Many reviewers appreciated the knowledgeable guides, even if they weren’t physically present, thanks to the clues’ quality. One shared that the experience made them see streets “they wouldn’t normally see,” adding a layer of discovery to familiar territory. Others found it “challenging,” but in a positive way, noting how it pushed them to think and explore more deeply.
A less favorable review pointed out that street closures for construction sometimes hampered the route, reminding travelers to be adaptable. Despite this, most found the experience more fun than stressful, and appreciated the cost-effective nature of the activity.

Considering the price, this treasure hunt packs in a lot of value. It’s an affordable way to combine sightseeing, puzzle solving, and light physical activity—all in one. The inclusion of hidden sights, historical facts, and the chance to challenge friends makes it a compelling alternative to typical guided tours.
This experience is particularly suited for travelers who enjoy an interactive approach to sightseeing and those eager to discover parts of London that often go unnoticed. It’s perfect for small groups or couples wanting a tailored, intimate experience. The flexibility to pause at pubs adds a social element, making it ideal for a leisurely afternoon.
However, if you prefer guided commentary or are less comfortable navigating on your own, a traditional guided tour might suit you better. Still, for those who love a bit of a challenge and an active way to explore, this treasure hunt offers a memorable and authentic way to spend a few hours in London.
This treasure hunt experience in London offers a unique blend of history, fun, and discovery. Its appeal lies in its flexibility, affordability, and the opportunity to explore hidden corners of the City of London that most visitors miss. The clues are well-designed, engaging, and accompanied by captivating stories, making it more than just a walk—it’s an adventure.
While some minor hiccups—like street closures—are possible, they don’t diminish the overall enjoyment. The inclusion of pub breaks and the chance to challenge friends adds a social layer that elevates the activity beyond a simple sightseeing walk.
This tour is a fantastic choice for curious travelers, puzzle lovers, or small groups looking to explore London in a lively, interactive way. It’s a budget-friendly, flexible, and memorable experience that turns sightseeing into a game, encouraging you to see London from a fresh perspective.
