What is a CERN Visit?

The CERN Visits Service organises guided tours free of charge, in several languages, from Monday to Saturday, at 9:00 or at 14:00. Reservation is obligatory.

A visit lasts approximately half a day. It consists of an introduction to CERN presented by one of our guides, followed by a film projection and a visit to one of the experimental areas and/or to an accelerator on the surface. It is also possible (for groups of more than 12 people) to have a longer visit (to two of the experimental areas) under certain conditions.

The choice of the itinerary is made by the Visits Service depending on the availability of the area on the day of your visit.

Please note that your reservation is not confirmed until you receive a reply from the Visits Service, so it is not advisable to make any other booking (of transport, accomodation, etc) until then.
