The Illumination trail is a one-mile paved walking path that includes a large incline approximately halfway through the exhibition (Ornament Hill), and several smaller inclines and declines. We advise guests to keep the length and hilly nature of the trail in mind. The exhibition is not fully accessible to visitors with limited mobility.
Guests have the option to skip the second half of the exhibition, bypassing the large incline at Ornament Hill, by heading back toward the Visitor Center on the tram road.
The Arboretum has a small number of non-motorized wheelchairs available free of charge in the Visitor Center. Guests must leave a driver’s license or other photo ID to check out a wheelchair. Because our supply is limited, we recommend bringing a wheelchair to the Arboretum, if needed.
Arboretum staff make best efforts to clear the path of ice and snow. Crowds are generally lighter on Tuesday, Wednesday, and Thursday making it easier to navigate the trail.
Please be aware that Illumination features moving and flashing lights along the trail, in case a member of your party is sensitive to these effects.
The Morton Arboretum welcomes visitors with service animals to Illumination. (However, please note, pets are not permitted at the Arboretum except on special dog admission days.)
The exhibition is not visible by car. Parking is available near the entrance for those with a disability placard on their vehicle—as it will be dark outside, please notify the parking attendant as you drive in. Otherwise, parking is first come, first served, and is directed by parking attendants.
Guests directed to secondary lots can take advantage of shuttle buses which will transport them to the main event area. If you do not have a disability placard and someone in your party has mobility concerns, you are welcome to drop off passengers in our circle drive adjacent to the Visitor Center before you park. Again, please notify our parking attendants and they will direct you accordingly.
