Out of concern for the health, safety and well-being of our community and staff, SLAC is cancelling all public tours until further notice effective immediately in response to the rapidly evolving events surrounding COVID-19. 

Please check this website for the latest update on the tours program in April.

SLAC National Accelerator Laboratory offers free public tours. Tours last approximately 90 minutes and usually include a visit to the lab’s 2-mile-long linear accelerator, now driving the world’s brightest X-ray source.

Tours are offered twice a month, by registration only.

All public tours meet in the SLAC Orientation Theater (Room 1010), Building 53, 15 minutes prior to tour time. Closed-toed shoes are required.

Tours are open to all visitors 12 years of age and above. Children 12-17 years of age must be accompanied by an adult; tickets are required for both the minor and the escorting adult.
