Come have a look at LIGO! At 1:30 PM on the second Saturday and at 3:00 PM on the fourth Friday of every month we offer free public drop-in tours that will give you an excellent look at our facility. If you have a group of your own of at least 15 participants, we can schedule a private weekday or evening tour. We regularly provide tours for community groups, astronomy clubs, professional societies and others. Tours usually last about two hours. Tours work best for participants of middle school age and up, but all ages are welcome. No reservations are necessary. Badges are not required for entrance to LIGO. LIGO's facilities are wheelchair accessible.
