All CERN guided tours are free of charge and are by reservation only.
Permanent exibitions are freely accessible without prior booking and you can discover them at your leisure: Science Gateway (Opening hours).
We are trying to organise guided tours (limited numbers, subject to registration) during the morning of the event. If you are interested to particpate in one of these tours you need to sign up at registration time and take note of the safety instructions.
NB: Tours are still to be confirmed but must be reserved at event registration time!
