Join us for the ECOS 2025 Rally Paper City Hunt, an unforgettable adventure through the heart of Paris, specially crafted to bring participants together after a day of intense conference sessions! This high-energy social event combines fun, teamwork, and discovery, as teams race across the city solving clever clues, facing playful challenges, and uncovering the scientific, cultural, and historical gems of the City of Light.
🧐 A Rally Paper is a city-based treasure hunt where teams follow a trail of tasks, puzzles, and questions, moving from one spot to another while working together to complete the course and enjoy the journey.
The theme Paris, Sciences et Lettres is both inspired by and held in honor of Université PSL, the distinguished host of ECOS 2025. Through this theme, you’ll experience a unique mix of games, and trivia, all while exploring some of Paris’s most iconic monuments and hidden corners.
Whether you register solo or with others, you’ll be grouped into a team for an evening full of connection, laughter, and exploration. At the end of the hunt, all teams will come together for a friendly gathering to share a drink, exchange stories, and celebrate the experience in good company.
Let Paris be your playground — don’t miss out, register now and be part of the fun!
👉The registration form will be sent by email to all ECOS participants.
