Access to our interactive exhibitions, as well as to science shows and films (subject to availability), is free upon registration via our form. However, bookings for guided tours and lab workshops can only be made on-site and on the same day.

For about ten years, CERN offered online booking for guided tours for families and individual visitors. However, this system showed its limitations:

• All spots were taken every morning in under two seconds (literally), which caused a lot of frustration — see this video between 00:23 and 00:40 to get an idea;
• Many visitors with reservations did not show up;
• Many arrived late, disrupting the schedule;
• Waitlists had to be managed, without any guarantee of securing a spot.

Due to very high demand and limited capacity, only about 10% of visitors to the Science Gateway will be able to take part in a guided tour or lab workshop.

We invite you to check the booking page for families and individual visitors to see the full booking conditions.
