Access to our interactive exhibitions, as well as science shows and films (subject to availability), is available after registering through our form. However, guided tours and laboratory workshops can only be booked on site, on the day of your visit.

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

• All available slots were taken every morning in less than two seconds (literally), leading to considerable frustration — see this video between 00:23 and 00:40 for an example;
• Many visitors who had booked did not show up;
• Others 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 Science Gateway visitors will be able to join a guided tour or participate in a lab workshop. However, the other activities offered will allow you to enjoy an experience of more than 3 hours.

We invite you to consult the booking page for families and individual visitors to learn more about access conditions.
