Key information

	Bookings are opened 9 months in advance and all capacity is usually taken in a few days. Please note that due to opening of Science Gateway during second semester of 2023, we are not in position to accept any more guided tours for groups before Science Gateway full opening. Bookings will be possible in the next weeks. Keep checking this page for up to date information
	Our guided tours are free of charge Refuse any offer from a Tour Operator which claims they had to pay for the CERN guided tour
	Tours consist of a video introduction to CERN, followed by a visit of one or two areas on the site, such as control rooms, research facilities, engineering facilities, etc. Tours take place both indoors and outdoors. Please note that underground visits are extremely rare and only possible when the accelerators are not running and that the LHC tunnel cannot be visited. The final tour programme is decided maximum 20 days before the tour in order to take operational and safety constraints into account, as well as group profile (ages, special medical condtions etc.). Therefore, the exact programme cannot be guaranteed in advance. In addition to your tour, you can explore our permanent exhibition Universe of Particles, located on the ground floor of the Globe of Science and Innovation.
	From Monday to Saturday Exceptional closures
	Tours last between 2 and 3 hours depending on programme and group availability It is not possible to leave a tour before the end
	For groups of 12 to 48 visitors
	Mandatory registration available 9 months in advance The approval or reject of your guided tour request depends on various parameters: your group category and size, the requested language, your country of origin (to guarantee a fair balance between countries), whether or not you have your own coach, the requested dates, etc. It is not unlikely that all capacity is booked months in advance. It is  therefore recommended to book as early as possible (i.e. 9 months in advance).
	Recommended for ages 12+ Minors must be accompanied by at least one adult Groups of minors must be accompanied by at least 2 adults
	Most tours will require the use of a coach CERN has a limited number of coaches available Having your own coach for the tour increases your chance of getting a place
	Up to 30 languages (depending on guide availability) French and English always available Please refrain to request a guided tour in a language that is not easily understood by participants. On the spot interpretation does not allow a tour in good conditions (shortened programme, lack of interactivity with the guide etc.).
	Requests from tour operators will be systematically rejected Requests for school/university groups must be submitted via an official school or university e-mail address
