How do I make a group reservation?

Reservations will be accepted up to two weeks prior to your planned visit. However, we recommend scheduling your group visit at least one month in advance. Spring visits should be scheduled as early as possible. A limited number of group reservations are available each day. Please call 317-334-4000 or 800-820-6214 between 9 a.m. and 5 p.m. daily to schedule a visit. Or reach us by fax. Send the completed registration form to: Customer Service Center 317-920-2001.
