Site Entry Information

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 or for tours, 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.

Members of the media should contact the Media Relations Manager prior to visiting.
