CERN visits service faces demand for guided tours which is about 3 times higher than what the offer is.
For about 10 years, CERN has offered online booking for Individual guided tours but the experience showed that:
- All capacity was gone in 2 seconds (literally) which created a lot of frustration (watch this video between 00:23 and 00:40 for an example)
- Many visitors who had booked online did not show up on the day of the tour
- This led to the handling of waiting lists which were not even a guarantee to get a tour
For those reasons, guided tours for individuals can now only be booked on site and on the day.
In order to guarantee visitors coming later at CERN a chance to get a guided tour, the on site booking is limited to 2 hours in advance (i.e. you can book a 16.00 tour as from 14.00, leaving you enough time to visit our exhibitions in the mean time).
Don't forget that our permanent exhibitions are freely accessible without booking.
