Schedule and Location
Trolls will remain through 2018. Trolls may be on view into 2019 depending on how they weather the Chicago winter.
Journey through our far-reaching forest to hunt for six colossal trolls crafted from reclaimed wood by Danish artist Thomas Dambo. Marvel at these 15- to 30-foot-tall (and one 60-foot long) sculptures that have been created to serve as protectors of our environment.
These mysterious creatures—resembling the trolls of European folklore—were first spotted at the Arboretum in the spring of 2018. As sightings increased, an official investigation was launched to learn about these fascinating new residents.
The trolls share the Arboretum's desire to care for trees; however, they seem suspicious of humans. We need you to join the investigation and help trolls and humans come to understand each other. What will you discover when you join the hunt?
Join the adventure and pick up the Troll Hunter's Handbook when you arrive. The Handbook will help you find a clue for each troll to locate the Troll's secret hideout, complete with a troll-size toothbrush and other troll essentials.

All trolls are located between two feet and three-quarters of a mile from the nearest parking lot on a variety of path surfaces (pavement, wood-chipped, and mown grass).
The trolls will reside on the Arboretum's grounds as long as possible, with the expectation that they will be available for visitor enjoyment through the remainder of 2018.
Spoilers ahead! Visit Troll Hunt accessibility for specific information about troll locations and how to access them.
