Field Trips


The LIGO Hanford Observatory offers FREE field trips for students of all ages. Field trips are available Tuesday – Friday, between 9:00 a.m. and 3:00 p.m., and last 2 to 3 hours. Trips include a walking tour of the observatory, during which students learn about our search for gravitational waves, meet and interact with LIGO scientists and engineers, get a fantastic view of the arms of our interferometer stretching 4 km (2.5 miles) off into the distance, see the control room, and explore hands-on exhibits.

LIGO is a genuinely multidisciplinary project that encompasses many science, math, and engineering concepts. Several Next Generation Science Standards (NGSS) are clearly illustrated by the work conducted here. We stand at the forefront of modern science and technology, and while some aspects of LIGO are fairly advanced, visits to LIGO are engaging to students of all ages.

Need to Know

  • There are no food facilities at LIGO. If you wish to eat lunch during your visit, please plan to bring your own.
  • We recommend one chaperone for every 10 students.
  • LIGO Hanford's location isn't recognized by most mapping and direction-finding services. Please check our web-viewable driving directions to help your field trip bus find our facility.
