Guided tours for groups



  • Guided tours for groups are proposed to non-students groups of between 12 and 48 (48 is a maximum including accompanying adults).
  • 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.
  • For groups of minors, there should be at least 2 accompanying adults.
  • All tours are free of charge.
  • Tours are available from Monday to Saturday, both mornings and afternoons.


  • Each tour lasts about three hours and includes an introduction with a short film followed by a visit to one or two of the visit points (normally at ground-level).
  • Please note that, in general, it is not possible to visit the underground experiments, especially for visitors under 16.
  • For safety reasons, most of our visit point are not open to pupils younger than 12 years of age and therefore the offer is limited.

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

  • CERN is open to all but receives many more requests for places on tours than it can accommodate.
  • Even though CERN considers outreach, and therefore guided tours, as part of its key 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 130,000 visitors each year on guided tours).
