Destination: the Universe, immediate departure


How would you like to take a tour of 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.

The LHC was designed to explore the biggest mysteries of our Universe... What happened after the Big Bang? How did our Universe evolve? These are just some of the many questions being investigated.


What is the Passport to the Big Bang?

  • Ten exhibition platforms above ten LHC key points
  • Riddles to solve with the family
  • The LHC Mission challenge
  • A cycling route

No reservation is necessary, the activity is freely open to the public all year round. So get on your bike and start the mission!

For all practical aspects, consult our FAQs.
