Imagine wandering through the historic streets of Grenoble, solving puzzles, and uncovering secret clues on your own terms—without a guide, without a fixed schedule. That’s exactly what the Curse of the Doomed Passage offers. This outdoor escape game is designed for groups of friends, family, or colleagues eager for a challenge that blends history, mystery, and a bit of theatrical fun. We haven’t played it ourselves, but from what’s shared, it sounds like a lively, engaging activity that’s both affordable and flexible.
What we love about this experience is how it turns a regular city walk into a story-driven adventure. The idea of hunting for hidden codes and meeting virtual noble families makes it feel like stepping into a Sherlock Holmes mystery—only in your own neighborhood. And the fact that you can play on the same day without pre-booking adds a nice touch of spontaneity. The other big plus? The photos and videos you collect are saved directly to your smartphone, making it easy to relive the fun or share it with friends later.
That said, there are a few considerations. The game relies entirely on your smartphone’s connectivity, so if your network is spotty, some clues or photos might be harder to access smoothly. Also, since the game ends after two hours, it’s best suited for those who enjoy brisk, puzzle-solving activities rather than slow-paced sightseeing.
If you like interactive experiences that involve a bit of problem-solving and storytelling and you’re visiting Grenoble or nearby Alpe d’Huez, this outdoor escape game is a playful way to add some mystery to your trip. It’s especially ideal for non-skiers or those looking for a different kind of adventure on a gloomy day or when you want a break from mountain sports.

To find the hidden access point in Grenoble’s vibrant city streets before it disappears forever in just two hours. The game’s narrative is woven around thwarting this evil fate, which adds a layer of tension and excitement to your walk through the city center.
Starting at Place Joseph Paganon, your team will download a handy app—free of charge—and receive a unique game code. From there, you’ll follow clues, solve puzzles, and meet with virtual noble families and their servants— all staged through your smartphone. The game’s structure involves gathering four code words from different families, which will ultimately lead you to the location of the secret platform.
You’ll visit various sites and landmarks, with each stop offering a mini-riddle or mystery. The clues are connected through a narrative that feels immersive, even though it’s all digital. Many reviews mention that the puzzles are well-designed, with some users noting they used clues to push forward when stuck. This indicates a good balance of challenge and fun.
Because the game is played outdoors, you’ll get a chance to explore Grenoble’s charming streets and learn bits about the city’s character. The activity is designed for groups of up to six, fostering teamwork and lively conversations. And since it’s a self-guided activity, you can control the pace and timing—perfect for fitting into a busy travel schedule or avoiding the need for a tour guide.
The Practical Side: Duration, Price, and Logistics
At around two hours, this activity offers a satisfying mix of puzzle-solving and sightseeing without feeling rushed. The price of $80.14 per group is reasonable, especially considering the number of participants it can accommodate. It’s comparable to many indoor escape rooms but offers the added bonus of outdoor exploration and a flexible schedule.
The activity begins at Place Joseph Paganon, located conveniently near public transportation, making it easy to access without fuss. Because there’s no physical guide, your experience depends on your smartphone and Wi-Fi network. This reliance on connectivity is a small caveat—if your network is weak, some clues or photo functions might be slower. Still, many users seem satisfied with the overall flow and the fun of solving mysteries at their own pace.
