In a few days, CERN opens its doors to everyone!
On Saturday 28th and Sunday 29th of September from 9 in the morning until 8 in the evening you can meet people working here, visit CERN installations and descend 100 meters underground to the experimental caverns!
The visits are available to everyone and are free. There are 35 sites on surface which you can visit anytime, but you will need a (free) ticket to get to the underground sites. You can reserve one here: https://opendays-tickets.cern.ch/ and make sure you’ve read the safety information: https://opendays2013.web.cern.ch/safety !
