Tours & Events

February 23, 2022


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


School field trips are suspended until late spring 2022, when we hope to open our new visitor education center, LExC. Visit the Field Trips page for more information.


In an effort to continue to prevent the spread of COVID-19, LIGO Hanford Observatory remains closed for all tours and drop-in visitation until further notice, and has suspended field trips until late Spring 2022 (visit the Field Trips page for more information). We apologize for the inconvenience.
