Guided tours for individuals


CERN offers guided tours to individuals or groups of less than 12 visitors in English and French.
Tours will be organized in groups of 24 visitors in the same language. CERN organizes up to 5 such tour every day, up to 8 during the Summer.
All tours are free of charge.

The tour offers an introduction to CERN, followed by a visit to an 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 lasts around two hours and is on foot and takes place outdoors and indoors.
Please note that these tours do not include any underground visits.

Due to the nature of our activities, we recommend that children be aged at least 12 years to join guided tours.
Our permanent exhibitions are more suitable for younger children. Minors MUST be accompanied by at least one adult.

In addition to your tour, you can explore our two permanent exhibitions: the Microcosm, next to Reception, and the Universe of Particles, on the ground floor of the Globe of Science and Innovation  - (Opening hours).

  • Even if CERN considers outreach, and therefore guided tours, as part of its fundamental missions, its main mission is fundamental research.
  • Therefore, budgetary, technical and safety constraints limit CERN visits service's capacity (even though CERN welcomes more than 120,000 visitors each year on guided tours).
