Special Nights

IllumiBrew

At IllumiBrew, a festival-style event for adults 21 and older, guests can get a first look at this year’s Illumination experience while tasting local beers and brews along the festive trail.

Sensory Night

The Illumination Sensory Night offers a modified experience featuring static lights and music at low volume. Tickets will be available in a limited capacity to provide a sensory-sensitive environment.

Electric Illumination

Electric Illumination is a special experience with a live DJ and a new mix of curated music each week.

Dog Admission Nights

Guests can bring their canine companions to be part of the fun. Illumination Dog Admission Nights are hosted throughout the Illumination season. Dog tickets must be purchased separately.

Accessibility

The Illumination trail is a one-mile paved path that is ADA-compliant. The paved path is walkable and rollable for wheelchairs, mobility devices, and strollers.

The exhibition is not visible or accessible by car.

Wheelchair Rentals and Personal Mobility Scooters

The Arboretum has a small number of nonmotorized wheelchairs available to rent free of charge in the Visitor Center. Guests must leave a driver’s license or other photo ID to check out a wheelchair.

Because the supply is limited, we recommend bringing a wheelchair to the Arboretum if one is needed. Wheelchair rentals are available on a first-come, first-serve basis.

Personal mobility scooters may also be used on the trail.

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.

Sensory Needs and Supports

Please be aware that Illumination features moving and flashing lights along the trail. There are no strobe lights in the exhibition. Laser features are directed away from guests and follow International Laser Display Association safety standards.

Guests may borrow sensory supports such as headphones, sunglasses, fidgets, or a copy of the Illumination social story (English, Spanish) when they arrive. Guests can use the social story to help prepare for their visit.

Any loaned items should be returned to the Information Desk in the Visitor Center before departure.

Illumination Sensory Night

The Illumination Sensory Night offers a modified experience featuring static lights and music at low volume. Tickets will be available in a limited capacity to provide a sensory-sensitive environment.

Accessible Parking

Parking is available near the Illumination entrance for those with a disability placard on their vehicle—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 a secondary lot (parking lot P-21), near the Thornhill Education Center on the Arboretum’s West Side, can take a shuttle bus that 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 also welcome to drop off passengers in the circle drive adjacent to the Visitor Center before you park. Please notify the parking attendants and they will direct you accordingly.
