CERN offers tours for groups of 12-48 persons (48 is a maximum including accompanying persons). All tours are free of charge.
Tours are available from Monday to Saturday, both mornings and afternoons. Each tour lasts about three hours and includes an introduction with a short film followed by a visit to one or two of the ground-level visit points. Please note that it is not possible to visit the underground experiments. For safety reasons, most of our tours are not open to children younger than 13 years of age and therefore the offer is limited.
We receive a very large number of visitors every year, so all tour requests are subject to availability. Please note that your request has not been accepted until you receive an official confirmation from the Visits Service by e-mail. If you do not receive a response five working days after submitting your request, please contact our service by e-mail.
In addition to your tour, you can discover the two permanent exhibitions at your leisure: the Microcosm, next to Reception, and the Universe of Particles, on the ground floor of the Globe of Science and Innovation - (Opening hours).
Please check the following important instructions. Failure to respect any of these instructions may lead to your guided tour being cancelled.
Reservations of tours for groups open 3 months in advance and request must be submitted by one of the accompanying contact person. Requests submitted by agencies or tour operators are not valid.
