Private Tours

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.


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.  We apologize for the inconvenience.


Tours are currently suspended. When we are able to reopen after the COVID crisis has passed, groups of 15 or more can schedule a private weekday tour of the observatory. We have provided such tours to a wide range of groups, including families, college organizations, teachers, conference attendees, scout troops, science clubs, and colleagues from other scientific research facilities such as PNNL. If you have a group of 15 or more who are interested in seeing LIGO, a private tour may be right for you.

During your visit you will see many interactive and static exhibits, including a full-scale engineering model of the "quad suspension" that is so critical to LIGO's success. You will also experience an extraordinary view of the interferometer's arms stretching 4 km (2.5 miles) off into the distance, get up close to a sample of the beam tube and its concrete enclosure, and visit the control room where you will learn more about our remarkable instrument.
