Drop-in Visits

February 23, 2022


LIGO Hanford Observatory has suspended ALL outreach activities including second-Saturday tours and drop in visitation until further notice. We will update this page as soon as we are certain we can welcome public groups once again.


In an effort to continue to prevent the spread of COVID-19, LIGO Hanford Observatory remains closed for all tours, field trips, and drop-in visitation. We apologize for the inconvenience.

We will post a re-opening date here and on the LHO home-page as soon as we have one.
