Community Public Tours

These tours are offered on a limited basis. 

LIGO Livingston in Louisiana offers guided tours on a limited basis for community and special interest groups.

If your group has fewer than 15 people, we invite you to visit during our Science Saturdays—held on the first Saturday of every month. No tour request is needed for these public days.

Important Note:
For group tour requests of more than 20 people on dates other than Science Saturdays, our Tour Request Form will reopen in the third week of July 2025. This temporary closure is due to our annual professional development workshops.

**Tour Request Form is currently CLOSED**
