The Arboretum's one-mile tree-light trail opens its fourteenth season with new displays.

Illumination begins its fourteenth season with four new large-scale installations and a new model-train add-on along the route. The one-mile paved trail makes this a walk-through winter light experience, with enough changes to reward visitors who have attended before.

What to expect

Dress for a one-mile outdoor walk and arrive close to the time printed on your ticket. The trail is paved, accessible to wheelchairs and strollers, and designed for visitors to stop at displays at their own pace. Prioritize the four new large-scale installations; families can also consider the Pine Whistle Railroad, which requires a separate add-on ticket.
