Practical and access information about the CERN Open Days

A new system for tracking visitors to CERN’s underground sites has been successfully tested by CMS and is ready for use at all targeted locations

Certain roads around CERN’s two main sites will be closed to traffic and a system of free car parks and shuttles will be available
