LIGO Hanford is located in the Columbia Basin region of Eastern Washington near the Tri-Cities of Richland, Kennewick, and Pasco. Our facility operates in tandem with the LIGO Livingston detector to listen for the faint whispers of gravitational waves from the most energetic events in the universe.

LIGO Hanford holds monthly site tours, offers school field trips, and hosts the occasional special public event, all centered on the LIGO Exploration Center, LExC. Use the menus above to find our tour and event schedules, and to learn more about the science and engineering that are driving the search for and study of gravitational waves.
