Main site tours

Since starting tours at Lawrence Livermore National Laboratory, we have welcomed hundreds of thousands of people to learn about our recent scientific discoveries, the achievements of our scientists and engineers, and the impact of breakthrough Livermore technologies. However, nothing is more important than the health and safety of our employees and visitors. For that reason, in-person tours were paused at the beginning of the COVID-19 pandemic, and remain on hiatus as we monitor the community situation. More information will be provided here when the program restarts. Thank you for your understanding. In the meantime, please visit LLNL’s Virtual Tour Map to learn more about the Lab, our facilities and our workforce.

Livermore Site and Site 300 Superfund Tours

Lawrence Livermore’s Environmental Restoration Department hosts Superfund tours for the general public at the Livermore Site and Site 300. These annual tours provide a close-up look at the ongoing effort to remedy legacy soil and groundwater contamination at each site dating as far back as the 1940s, when the Livermore Site served as a U.S. Naval air station. The tours are anticipated to resume in 2023, and information will be announced here and in other media.
