Booking Rules

The CERN hotel located on the CERN site in Switzerland is not open to the general public. Access is restricted to certain categories of people, connected to the official activities of the Organization.

The hotel Reception staff cannot offer a reservation before clarifying the reason for the stay as they need to check that the enquiry emanates from a person entitled to use the CERN hotel facilities. See How to book a room in the CERN hotel.

IMPORTANT: All persons entering the CERN site must be in possession of a card issued by CERN certifying that they are authorised to do so. Access cards are issued by the Registration service and Access Control Service in Building 55 or Building 33. CERN guarantors may apply for a limited-duration visitor's card on behalf of another person by sending an e-mail to the following address: or creating a request through the Service Portal: Request for a CERN visitors card.
