Guided tours (upon reservation)

I cannot select the date of my choice. Is this normal?

Guided tours can be requested only:
- 9 months in advance for school and students groups (12-48 persons)
​- 3 months in advance for other groups (12-48 persons)
​- 15 days in advance for groups of less than 12 persons

​CERN receives about two times more guided tours request than it can accomodate. Try another date.

Why do you ask if we have our own bus?

Some of CERN's visit locations are located remotely from CERN Reception (up to 15km away). It is therefore important to organize transport. CERN has limited transport service. If you have your own bus, we will use it during the visit to travel between visited locations. Please make sure the driver is aware and ready to drive you. Please note that the use of individual cars is not allowed. Only buses (from 20 to 50 seats) are allowed to enter our sites with guided tour visitors.

Who conducts the CERN tours?

Tours are conducted exclusively by members of the CERN personnel.

How long does a guided tour last?

Tours last between two and three hours. In addition, you will have opportunity to visit the two permanent exhibitions on the CERN site.

Can I visit underground?

Underground tours are not permitted while the LHC is in operation.
The LHC tunnel can never be visited.
Very limited underground visits are possible in experimental caverns during LHC shutdowns.

As a general rule: underground visits are extremely rare and cannot be guaranteed.
But there are many interesting places to be visited above ground.

Do I need to bring an identity document?

Yes, CERN's site are located on either side of the French-Swiss border and you might cross the border during your tour. A valid ID document is therefore necessary.

Can CERN provide a risk assessment document or help to write one?

No. As the applicable laws differ from one country to another, CERN is unable to provide a standard risk assessment document. A medical service and fire brigade are based on site and strict safety rules are in place to protect everyone working at or visiting CERN.

How can I cancel a tour ?

Connect to, select the requested tour and click on Cancel the guided tour button on the top.

How can I request a change of date, number of visitors, use of restaurant, language etc for my guided tour ?

Please send an e-mail to referring to your request id.

Do I need to provide the list of visitors' names?

Yes. Guided tours enter CERN sites and all visitors must wear visibly a personal visitor's card.
​Once your guided tour request has been approved, you will have access to a form to provide each visitor's identity on

Form on does not accept some names. Is this normal ?

Make sure you only enter latin, unaccented characters, such as in the machine readable zone of identity documents.

Do I have to fill in all visitors information in one go?

No. You can save and come back later to input more visitors information. All visitors' information must be provided within 48 hours (for individual guided tours) or at least 21 days before the guided tour (for group guided tours) otherwise the incomplete visitor will be removed.

Can I modifiy the visitors' information and until when?

Yes you can and are more than welcome to inform us on any visitor change until 1 day prior the guided tour. During that last day, no updates are possible to allow us to print the visitors' cards.

What should I do if I have last-minute changes to visitors information that I could not apply in time?

As soon as you arrive at CERN Reception, please inform us of these changes. You will be requested to provide all the changes or delete visitors who are finally not coming. Please note that the time needed to provide this information may impact the duration of your guided tour. It is therefore advised to inform us online up to 1 days prior the guided tour.

No. Only the approved number of visitors will be allowed to get the guided tour. Any additional person may visit the permanent exhbitiions during the guided tour.

I do not know the identity of the bus drivers. What should I do?

This information is not mandatory before your arrival. But you will have to provide this information at the latest as you arrive at CERN Reception. Make sure to have this information with you.

For the attention of tours organisers:

School visit organisers often wish to produce a t-shirt or other item for their group. We would like to remind you that the CERN logo is the property of CERN, and that its reproduction on any item produced by an external organisation is not permitted under any circumstances, including in the context of a school visit. However, the use of phrases such as “Visit to CERN, Geneva, Switzerland” is acceptable.
