Secret City, the treasure hunt that reveals the city
What awaits you.
For half a day, the city becomes your playground. Your teams will explore a neighbourhood and discover its secrets, anecdotes, architectural details, and forgotten stories through a series of fun challenges: quizzes, blind tests, and on-site riddles. This is one of our corporate treasure hunts: 1h30 to 2h30, for 10 participants and up.
Immerse your teams in the neighbourhood of your choice! Squares, alleyways, facades, and forgotten anecdotes: your colleagues will explore the city at their own pace, tablet in hand. A challenge awaits them at every stage: navigation, observation, research, creative challenges, blind tests, photo challenges, puzzles, or mini-games. The neighbourhood becomes a playing field, and its secrets are points to be scored.
Three reasons to choose this urban exploration:
- Discover a neighbourhood from an unexpected angle, through its architectural details and forgotten stories
- Play as a team with varied formats, quizzes, blind tests, on-site riddles, requiring no specific prior knowledge
- Progress at your own pace, with rankings rewarding observation as much as speed
