Planning a trip to Paris and looking for something beyond the usual sightseeing? This treasure hunt and walking tour promises a different way to experience the city, combining puzzles, history, and a bit of adventure. From what we’ve seen, it’s a fun activity that’s particularly suited for those who enjoy engaging, hands-on experiences rather than just sightseeing from afar.
What really caught our eye is the way this tour combines learning and exploration—you get to discover secret places in Paris while solving puzzles based on the city’s history. Plus, the story involving Marie Curie’s hidden weapon adds a layer of intrigue that makes the experience feel like a mini adventure story. We also appreciate that it’s a budget-friendly option at just $29 per person, offering a good mix of value and fun.
However, one thing to consider is that this isn’t a typical guided tour with a large group or a chatty guide walking alongside you. Instead, you’ll be following a treasure map and solving puzzles at your own pace, which might not suit travelers who prefer a more structured or commentary-rich experience. Still, if you’re curious about seeing Paris from a new perspective and enjoy interactive activities, this could be just the ticket.
Ideal for friends, families, or even small groups, this tour offers a unique way to explore Paris’s top attractions while engaging your brain. If you’re up for a self-guided adventure that feels like an escape room on the move, this is worth considering.

A Detailed Look at the “Secret Weapon X” Treasure Hunt

If you’re tired of the same old walking tours, this outdoor escape game offers something more engaging. It’s designed for those who like their sightseeing with a bit of brainwork thrown in. Starting at Play-In on 59 Rue de Rivoli, your adventure begins with a quick chat with a French soldier who hands you a backpack filled with all the necessary tools: treasure maps, boxes, and beautiful tools. Think of it as a portable puzzle set that takes you through the city.

The Start: Setting Off on Your Treasure Hunt
From the get-go, the experience feels quite authentic. Instead of a tour guide talking at you, your journey begins with receiving physical materials, which instantly makes it feel more like a treasure hunt. The treasure map is your key to navigating the city’s landmarks, and the tools help you solve the puzzles along the way.
The first part of the tour is about following the treasure map through some of Paris’s most recognizable sites. It’s a nice mix: you get to see top attractions, but with the added challenge of deciphering clues. This makes the sightseeing feel more purposeful, and just wandering around Paris can sometimes be a bit aimless—this activity adds a layer of engagement.
Exploring the City’s Top Attractions
As you follow the clues, you’ll pass some of Paris’s well-known sites. The route is designed to balance stunning views with hidden gems—which is a plus. You might find the experience especially rewarding if you enjoy seeing architecture and landmarks but want a reason to linger longer at each.
According to reviews, the pacing is just right. One reviewer mentioned that it’s “just the right distance on foot,” which is important because after a couple of hours, you don’t want to feel exhausted or rushed. Plus, the fact that there’s no timer means you can take your time, absorb the surroundings, and truly enjoy the moment.
Puzzle Solving and Learning
The core of this experience is solving puzzles while exploring. The activity involves physical boxes, books, and tools that are used to unlock or decode clues. This makes it more tactile than purely app-based games or smartphone-guided tours. Guests have said that the puzzles are “neither too difficult nor too obvious,” striking a good balance for a wide range of participants.
What’s particularly appealing in the reviews is the way the activity incorporates stories from Paris’s history. For example, you learn about Marie Curie and her connection to the city, adding an educational element that feels natural rather than forced.
