Community Public Tours
*** Unfortunately, due to current funding concerns we will not be able to accept more requests at this time. We hope to continue with these special events in the future. Please keep an eye on this page for updates. For any questions, please contact outreach@ligo-la.caltech.edu ***
We invite you to visit LIGO during our open days, "Science Saturdays"—held on the first Saturday of every month. No tour request is needed for these public days.
