All visitors must enter through the main gate off of Sand Hill Road. Stay in the left lane when turning from Sand Hill Road and stop at the guard house to present a valid, government-issued photo ID.

During public events, SLAC security staff will provide any necessary directions or parking information. At all other times, visitors must have prior approval of a SLAC employee, who will notify the gate in advance of your visit.

At this time, all public and educational tours of the laboratory have been suspended. We apologize for any inconvenience this may cause and we hope that you will check back here periodically for updates. Thank you for your interest in visiting SLAC.

Members of the media should contact the External Communications Manager prior to visiting.
