Content

• Tours consist of a video introduction to CERN, followed by a visit of two areas on the site, such as control rooms, research facilities, engineering facilities, etc.
• Tours take place both indoors and outdoors.
• The final tour programme is decided at the last minute in order to take operational and safety constraints into account. Therefore, the exact programme cannot be guaranteed.
• Please note that the vast majority of our tours do not include underground visits and that the LHC tunnel cannot be visited.

In addition to your tour, you can explore our permanent exhibitions: Microcosm, situated next to the Reception and the Universe of Particles, located on the ground floor of the Globe of Science and Innovation.
