This Illinois Arboretum Hides Giant Trolls Along Its Trails That Feel Straight Out Of A Fairytale
Picture wandering a wooded path in Illinois and turning a corner to spot a wooden giant peeking through the branches, taller than your house and made entirely from scrap lumber. For a few unforgettable years, colossal trolls dreamed up by a Danish artist stood watch over a sprawling nature preserve just outside Chicago.
Families drove in from all over to hunt them down, camera in hand. While those trolls have since packed up, the arboretum they called home still delivers plenty of wonder for a budget-friendly day out.
A 1,700-Acre Wonderland in Lisle

Sitting just off Interstate 88 in Lisle, this sprawling green giant covers a jaw-dropping 1,700 acres of trees, trails, and open sky. It works as both a public botanical garden and a serious research center devoted entirely to trees.
Located in DuPage County, it sits an easy drive from Chicago and its western suburbs, making it a doable day trip for much of northern Illinois. Regulars often admit they lived nearby for years before finally visiting, then kicked themselves for waiting.
Visitors describe the size as almost overwhelming on a first trip. Many folks arrive planning to spend a couple of hours and end up staying the whole day, still not seeing everything.
Sixteen miles of hiking trails weave through the property, alongside nine miles of paved roads open to cars and bicycles. That mix means you can lace up your boots or simply cruise from your seat.
The land itself feels like a living museum, holding tree collections gathered from around the world and arranged for both beauty and learning.
The Legendary Troll Hunt That Started It All

Back in 2018, six enormous trolls appeared among the trees, and word spread fast across Illinois. Danish artist Thomas Dambo built each one from reclaimed wood, giving them personalities that felt plucked from a storybook.
Ranging from 15 to 30 feet tall, with one stretching a whopping 60 feet long, these gentle giants scattered across the grounds turned an ordinary walk into a treasure hunt. Kids raced ahead searching for the next hidden face peeking through the leaves.
The exhibit, called Troll Hunt, ran from spring 2018 into early 2021 before the sculptures were retired. It became the kind of outing families still bring up years later at the dinner table.
Even now, trolls remain one of the most talked-about memories among visitors, mentioned hundreds of times over. Their popularity proved just how magical a simple wooded trail can feel with a little imagination sprinkled in.
While you can no longer meet the trolls in person, their legacy lives on in the arboretum’s ongoing love of large-scale outdoor art.
Vivid Creatures Now Roaming the Grounds

Wondering what replaced the beloved trolls? A brand-new outdoor exhibition called Vivid Creatures opened in spring 2025 and is set to stay through spring 2027, giving families plenty of time to plan a trip.
Five giant, brightly colored animal sculptures now dot the landscape, some rising up to 23 feet tall. Each one celebrates creatures native to northern Illinois, so there’s a homegrown twist to the whimsy.
You’ll find a white-tailed deer, a fox squirrel, a sandhill crane, a blue dasher dragonfly, and even a tiny brittle button snail blown up to enormous size. Artists Heather and Fez BeGaetz designed them with photos in mind.
Visitors are invited to walk right underneath and touch the sculptures, which makes for delighted little ones and plenty of camera-ready moments. First-timers have raved about how much fun the vivid figures added to their day.
Four of the five sit along paved, wheelchair-friendly paths near the Visitor Center, and a couple are even visible straight from the road.
The Children’s Garden Built for Wild Play

Little explorers hit the jackpot in the four-acre Children’s Garden, a hands-on playground disguised as a slice of nature. It’s the sort of spot that leaves kids talking about their day for weeks.
Secret streams trickle through the space, inviting small hands to splash and poke around. A colossal acorn stands ready for climbing, and giant tree roots double as slides for tumbling down with a giggle.
Parents and grandparents mention this area again and again as a highlight, and several say they spent a huge chunk of their visit right here. The design encourages free, unstructured play rather than staring at screens.
Because everything centers on discovery, kids learn about trees and water without ever realizing they’re learning. That sneaky mix of fun and education is exactly what makes it memorable.
One family noted they only allotted a few hours for the whole arboretum and quickly realized the Children’s Garden alone could swallow an afternoon. If you’re bringing young ones, budget extra time and maybe a change of clothes.
Getting Delightfully Lost in the Maze Garden

Few things spark laughter quite like hitting a dead end and doubling back through a wall of hedges. The Maze Garden offers exactly that old-fashioned thrill, and it’s a favorite for families chasing a bit of friendly competition.
Tall, neatly trimmed shrubs form the twisting corridors, and part of the fun is racing to see who finds the center first. Visitors regularly list the hedge maze among the top things they recommend.
Younger kids love the sense of adventure, while grownups enjoy the nostalgic puzzle of it all. It pairs beautifully with a stop at the nearby Children’s Garden for a double dose of play.
Because it sits within easy reach of the Visitor Center, you won’t have to trek far to enjoy it. That accessibility makes it a smart early stop before venturing deeper into the grounds.
Regulars who bring out-of-town guests often steer them straight toward the maze, knowing it delivers instant smiles. Simple, timeless, and free with admission, it’s a small delight that leaves a big impression.
Sixteen Miles of Trails Waiting for Your Boots

For anyone who loves stretching their legs, the trail network here feels almost endless. Sixteen miles of paths wind through wooded groves, prairie edges, and tree collections gathered from around the globe.
The routes range from long, ambitious treks to short, easy strolls, so every fitness level finds something comfortable. Benches appear at helpful intervals, giving weary walkers a spot to rest and soak in the scenery.
Visitors describe the paths as wide, groomed, and well-marked, which takes the guesswork out of exploring. One frequent guest even walks year-round, calling the trails their happy place through every season.
Wildlife makes regular cameos too, with birds, butterflies, and squirrels crossing paths as you wander. That constant flicker of movement keeps kids engaged and adults reaching for their cameras.
A quick word of advice from regulars: pack insect repellent, since the wooded, leafy stretches can attract mosquitoes after summer rain. Bring water as well, because with this many miles to roam, you’ll want to stay refreshed.
Cruising the Nine Miles of Scenic Roadways

Not everyone feels up for a long walk, and the arboretum happily plans for that. Nine miles of paved roads loop through the property, letting you experience the whole place from the comfort of your car.
One visitor called driving the main path absolutely jaw-dropping, pulling over at scenic stops whenever something caught their eye. On sweltering summer days, this air-conditioned option becomes a genuine blessing.
Pullouts and parking areas dot the route, so you can hop out for a short hike, snap photos, or simply sit on a bench and breathe. It’s the ideal setup for mixed groups where some want to stroll and others prefer to ride.
Cyclists share the roadways too, making it a great spot to bring bikes for a leisurely spin. Families with strollers appreciate having options when a section of trail gets bumpy.
Several folks who visited after rain noted they still saw the entire place by car, dodging the mosquitoes entirely. Flexibility like this is part of what makes the arboretum work for every kind of visitor.
Hopping Aboard the Acorn Express Tram Tour

First-timers often feel dizzy trying to figure out where to even begin on 1,700 acres. That’s where the Acorn Express Tram Tour swoops in to save the day.
Lasting roughly an hour to ninety minutes, the guided ride covers the sprawling grounds while a narrator shares stories about the trees and landscape. Visitors who lived nearby for over two decades admitted they finally understood the place after taking it.
The tour helps you map out the property so you know which areas to revisit on foot later. Guides sometimes offer a longer, more detailed version if the group votes for it.
One rider paid just ten dollars per person and called the trip well worth it, despite the seats being a bit hard. Others recommend it specifically for anyone visiting for the very first time.
Tour times are typically offered in the early and mid afternoon, so plan your day around a slot. Consider it the perfect orientation before diving into the trails, gardens, and sculptures on your own schedule.
The Story Behind Big Rock

Deep in the forest sits a massive boulder that stops visitors in their tracks. Known simply as Big Rock, it perches in the middle of the woods with a story worth reading right beside it.
A wood-chipped path leads you there, winding past birds, butterflies, and darting squirrels along the way. One visitor described the walk as peaceful and the rock itself as something you truly have to see in person.
Curious minds appreciate the little sign that explains why such a giant stone landed in the heart of an Illinois forest. It turns a simple stop into a mini history lesson for all ages.
The spot rewards those willing to wander a bit off the main routes, offering a quieter, more contemplative moment. Several folks wished they’d budgeted more time just to linger here.
For families, it’s a fun destination to hike toward, giving kids a clear goal and a satisfying payoff. Bring your curiosity, and maybe a snack, for this rewarding little detour into the trees.
Refueling at the Ginkgo Restaurant and Cafe

All that walking works up an appetite, and the on-site Ginkgo Restaurant is ready to fix that. Families have praised it as a delicious break from the heat and a comfortable place to relax mid-visit.
The menu spreads across salads, sandwiches, wraps, and hot dishes, plus a range of drinks to cool you down. One guest noted paying around thirty dollars for two sandwiches and two drinks, so plan your budget accordingly.
Regulars specifically call the food really good, which is high praise for a garden cafe. After the tram tour, it makes a natural spot to rest tired legs and swap stories about what you’ve seen.
Here’s a handy tip a repeat visitor shared: the dining room often has free water cups available, so you don’t have to buy every drink. Small savings like that add up on a family outing.
Whether you want a full sit-down meal or just a quick bite between trails, the cafe keeps your day rolling smoothly.
A Calendar Packed With Seasonal Events

One visit rarely captures everything, and that’s partly by design. The arboretum rotates vendors, performances, and special exhibitions throughout the year, so each trip offers something fresh.
Wintertime brings Illumination, a roughly one-mile walk lit up with glowing displays and occasional music. Guests describe it as a pretty, festive way to enjoy the grounds after dark during the holiday season.
Warmer months host outdoor theater, and one attendee raved about a walking performance of A Midsummer Night’s Dream with excellent actors. Art from various creators also rotates through the property year after year.
Wellness classes round out the offerings, from gentle mobility sessions perfect for active-aging adults to hands-on workshops. There’s genuinely a little something for every interest and age group.
Because programming shifts with the seasons, checking the event calendar before you go pays off. Some areas may be reserved for programs or maintenance, so a quick peek helps you plan.
Repeat members say the constant variety is exactly why they keep coming back, no two visits feeling quite the same.
Special Days When Dogs Get to Explore

Four-legged family members aren’t left out, thanks to designated Dog Admission Days. On these special dates, leashed pups can join the fun and stretch their legs across the wide, welcoming paths.
Visitors who attended one raved about the experience, noting there was absolutely no line to get in even on a rainy day. The extra room means dogs can pass other friendly visitors without feeling crowded.
It’s worth remembering that dogs are only allowed on these specific days, not year-round, so checking the schedule ahead of time is essential. The arboretum posts the dates on its website for easy planning.
Owners suggest bringing water and waste bags, since being prepared keeps the grounds clean for everyone. A few stations are available, but packing your own never hurts.
For dog lovers, few outings beat combining a scenic tree preserve with quality time alongside a happy pup. Just remember to be respectful of shared space, especially around the sculptures where photo-seekers gather.
It’s a thoughtful touch that makes the whole family, tails included, feel welcome.
Admission, Discounts, and Ways to Save

Let’s talk money, because a family outing shouldn’t break the bank. General admission runs about twenty-five dollars for adults and nineteen for seniors, while small children and infants get in free.
Buying tickets online in advance shaves two dollars off each one, a simple trick regulars swear by. That small step adds up quickly when you’re bringing the whole crew.
Several money-saving programs make it even friendlier for Illinois families. Active-duty military members and their families enter free, and the whole carload comes in free with a valid ID.
DuPage County residents snag a 33 percent discount on Wednesdays, and the Museums for All program lets EBT cardholders buy admission for just one dollar. One visitor with a link card paid only two dollars to get in.
Library museum passes offer another route, with one family calling it the best free experience they’d had in a while. Annual memberships unlock unlimited year-round visits plus perks at hundreds of other gardens across North America.
With this many options, there’s almost always a way to visit affordably.
Why This Arboretum Earns a Spot on Your List

Some destinations promise magic and fall flat, but this one keeps delivering season after season. Between its storybook art, endless trails, and family-friendly touches, it earns the loyalty its regulars gladly give.
Visitors consistently describe the grounds as beautiful, peaceful, and impeccably kept, with friendly staff pointing the way. Couples even return each fall to celebrate anniversaries where they were married among the trees.
The sheer variety means grandparents, toddlers, hikers, and photographers all find their groove. You can drive, walk, ride the tram, or simply sit on a bench and watch the world go quiet.
Plan for more time than you think you’ll need, since nearly everyone underestimates how much there is to see. Pack water, repellent, and comfortable shoes, then let the day unfold at its own pace.
While the famous trolls have moved on, their spirit of wonder lingers in every colorful creature and winding path. For an affordable, memory-making day in Illinois, this leafy giant in Lisle is tough to beat.
