Drop-in Visits


NOTICE: January 4, 2021

LIGO HANFORD OBSERVATORY HAS SUSPENDED ALL OUTREACH ACTIVITIES, INCLUDING SECOND-SATURDAY TOURS AND DROP-IN VISITATION UNTIL JULY 2021.

In an effort to minimize the spread of COVID-19 both to the public and to staff, the LIGO Hanford Observatory is closed for all tours, field trips, and drop-in visitation of exhibits.  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.
