CERN – Passeport Big Bang

How would you like a spin on the gas? The Big Bang Passport is an interactive walk to meet a science giant, the LHC.

The LHC is the largest particle gas pedal in the world. Its 27 km ring is buried 100 meters under the French-Genevan countryside.
It was designed to unravel the great mysteries of our Universe... What happened after the Big Bang? How did our Universe evolve? And these are only a few of the many questions.

A ride with the Big Bang Passport is...
- A bicycle route
- Ten exhibition platforms above ten key points of the LHC
- Riddles to solve with your family
- The LHC Mission Challenge
- Geocaches

No reservation is necessary, the activity is freely accessible all year round, every day. So get out your bike and start the mission!
