Destination: the Universe, immediate departure
How would you like to take a tour of an accelerator? The Passport to the Big Bang is an interactive circuit through which you can explore the Large Hadron Collider (LHC). The LHC is the world's largest particle accelerator. Its 27 km ring is buried 100 metres below the French and Geneva countryside.
What is the Passport to the Big Bang?
- Ten exhibition platforms located above ten key LHC points
- Riddles to solve with your family
- The LHC Mission challenge
- A cycling route
No reservation is necessary, and the platforms are freely accessible to the public all year round. So get on your bike and start the mission!
⚒ Some platforms are currently partially or entirely unavailable for maintenance reasons:
- Precision stage (Meyrin): Mission LHC activity currently unavailable. Code: 0000.
- Environment stage (Versonnex): Mission LHC activity currently unavailable. Code: 7639.
- We apologise for the inconvenience. Please report anything on the platforms that is broken or out of service by contacting us.
Caution: in case of frost or rain, the platforms' floor can be slippery.
