Only CERN guides are authorized in our exhibitions

Our exhibitions are interactive and were not designed to accommodate guided group tours, as these can negatively affect the experience of other visitors.

When a group includes visitors who do not speak any of the official languages (French, English, German, Spanish, or Italian) please check with our guides which languages they speak. As an exception, one person may accompany and guide up to 6 visitors at a time, provided they do not disturb other visitors and always give them priority.

Any misuse of this exception may result in exclusion from the exhibitions.
