Group tours of certain areas of CERN are highly in demand and, depending on the language, sometimes have a waiting list of several months. This is why we also offer tours for individuals and groups of maximum 11 people. You can sign up for a tour at much shorter notice. The tour itinerary is different to that of the group tours. All visits are free of charge.
The tour offers an introduction to CERN, allowing visitors to discover the history of the Laboratory and the latest scientific developments. The tour consists of a visit to a historic area of CERN and to the operations centre of one of the experiments. Immersive audio-visual presentations complement the information provided by the tour guide. The tour is in English or French and lasts around two hours.
Please note that this tour does not include an underground visit.
The tour is on foot (outdoors and indoors) with a maximum of 24 people in the group.
