Illumination at The Morton Arboretum opens Nov. 14 with its boldest winter wonderland yet

—Reimagined 14th season features 22 dazzling displays, including four new large-scale installations, and family-friendly Pine Whistle Railroad add-on experience—

LISLE, Ill., Nov. 10, 2026 — Illumination, The Morton Arboretum's nationally acclaimed outdoor holiday lights exhibition, returns Saturday, Nov. 14, with its boldest, most captivating winter wonderland yet. Running through Saturday, Jan. 2, 2027, the 14th season invites guests to see trees in a different light along an immersive, one-mile, ADA-accessible walking trail featuring 22 dazzling displays, including four spectacular new large-scale installations, and the debut of Pine Whistle Railroad, a family-friendly model train display inside the Arboretum's Firefly Pavilion.

A one-of-a-kind exhibition, Illumination offers returning and first-time guests new ways to explore the Arboretum after dark, from a spectacular, 400-foot canopy inspired by the northern lights to an enchanted landscape of glowing orbs and illuminated mushrooms.

"This year's reimagined Illumination invites guests to see the Arboretum in a completely new light," said Amy Scott, the Arboretum's head of exhibitions. "From Northern Lights, our most ambitious installation ever, to the imaginative world of Pine Whistle Railroad, we've created new ways for guests to explore, discover and enjoy the wonder of trees and nature in the winter. Alongside refreshed favorites and interactive displays, this season will offer something new and surprising for returning visitors and first-time guests alike."

Four Brand-New Large-Scale Installations
This season, guests will encounter four new large-scale installations designed to transform the Arboretum's winter landscape.

• Northern Lights is a mesmerizing canopy inspired by the aurora borealis, with shifting colors and shimmering illuminated curtains stretching more than 400 feet overhead. DON'T MISS IT! This is Illumination's most ambitious installation ever and will be available to experience during this Illumination season only.
• Lightwave features an immersive, 165-foot tunnel with 64 moving illuminated spheres surrounded by 160 fixed chrome spheres of varying sizes, inspired by falling rain and dew drops.
• Cosmic Garden transforms a sweeping hillside into a glowing landscape of 25 orbs and shifting patterns inspired by meditative sand gardens.
• Fairy Forest creates an enchanted woodland of glowing orbs evoking floating fairies and giant fireflies, alongside illuminated mushrooms and otherworldly elements.

Enhanced Returning Favorites and Interactive Features
Along the one-mile trail, returning fan favorites, including Treemagination, Golden Glade and Symphony Woods, will feature refreshed enhancements. Interactive displays such as Celebration Circle and the beloved Hug-a-Tree installation will invite guests to engage with light, color and music. Four larger-than-life illuminated Vivid Creatures sculptures by artists Heather BeGaetz and Fez BeGaetz will once again accompany guests along the trail.

Pine Whistle Railroad: A New Family-Friendly Model Train Display 
New this year, Pine Whistle Railroad transforms the Firefly Pavilion into a fantastical woodland world, featuring nearly 1,000 feet of model train track winding through detailed miniature scenes with fairy and gnome houses, oversized mushrooms and illuminated elements. Trains travel both overhead and at eye level as guests walk through the imaginative attraction.

Pine Whistle Railroad will officially open during daytime hours starting Friday, Nov. 13 as a ticketed add-on to general Arboretum admission. During evening Illumination hours, it will be available as a ticketed add-on to an Illumination ticket starting Saturday, Nov. 14.
