Fullersburg Woods Just Made the National Register. Technically, It's Not Even Hinsdale.

How many times have you crossed the footbridge over Salt Creek at Fullersburg Woods without knowing you were standing in the last physical piece of a town that no longer exists?

Most Hinsdale families treat Fullersburg Woods as their own backyard. It's where the stroller loop happens on Saturday mornings, where the dog gets the good walk, where out-of-town cousins get dragged to see the mammoth skeleton at the nature center. But the woods most people call "Hinsdale's woods" actually sit across the village line in Oak Brook. This summer, the federal government made that boundary question strangely official: in June 2026, the U.S. Department of the Interior added 177 of the preserve's 220 acres to the National Register of Historic Places. The listing isn't really about what you'd expect. It's not primarily about the creek or the wildlife. It's about a construction crew that worked here for five years during the Depression, and about a town called Fullersburg that Hinsdale absorbed so long ago that most residents have never heard its name.

The Town the Woods Are Named For

Before there was a Hinsdale, there was Brush Hill, and before Brush Hill had a different name, Jacob Fuller and his son Benjamin platted a town called Fullersburg in 1851. That settlement grew up along Salt Creek, built around what would become Graue Mill. Over the following decades, as Hinsdale incorporated and expanded, Fullersburg was folded in. According to a 2025 feature in the Hinsdalean, most of the original settlement was absorbed into Hinsdale more than 100 years ago, and the only place the name survives is the forest preserve that sits just across the current Hinsdale border in Oak Brook.

So the woods aren't named after a subdivision or a marketing gimmick. They're named after the actual town this stretch of DuPage County grew out of, a town that predates Hinsdale as an incorporated village and that no longer exists as its own place on a map. Walking the loop past the mill and the creek bend isn't just a nature outing. It's the closest thing left to visiting Fullersburg itself.

What Actually Got Listed in June

The National Register designation covers 177 of the preserve's 220 acres, and it's worth putting that number against a bigger one: the Forest Preserve District of DuPage County owns 26,000 acres across the county. Fullersburg's newly recognized footprint is well under 1 percent of that total holding, which makes it a genuinely unusual pick for this kind of dual recognition.

Board President Daniel Hebreard framed the listing around continuity rather than novelty. "Fullersburg Woods is one of the forest preserve district's most popular destinations, and this designation recognizes the history and architecture that continue to make it special today," he said, adding that visitors can experience many of the same landscapes, trails and shelters that have drawn people here for generations.

The timing lines up with the preserve's own history. The forest district purchased the original 65-acre tract along Salt Creek near Graue Mill in 1920, which makes 2026 its 106th year in public hands. Graue Mill itself, an 1852 gristmill, already had its own separate National Register listing dating back to 1975. This year's designation is a second, broader one, filed 51 years later, covering not the mill but the CCC-era construction that shaped the rest of the preserve.

The Stonework You've Walked Past a Hundred Times

That construction came from Civilian Conservation Corps Company V-1668, which built the trails, bridges and shelters at Fullersburg between 1933 and 1938. Sandie Gilmer, the forest district's heritage site logistics manager, put it plainly when the listing was announced: the designation recognizes the preserve's "long-standing impact on the community and the contributions made by the Civilian Conservation Corps in the 1930s."

That work is more visible than most visitors realize. The building that now houses the Fullersburg Woods Nature Education Center, the one with the woolly mammoth skeleton and the microscopes, started life as a CCC-built shelter and boathouse. It has been repurposed, not replaced, which is a big part of why the preserve qualified. According to the Hinsdalean, much of the original stone and timber craftsmanship remains today, making Fullersburg an example of the early 20th-century National Park Service rustic style, a design approach built around natural materials and structures meant to blend into the landscape rather than announce themselves.

Gilmer's point about the preserve's value isn't really about the trails at all. "A visit to Fullersburg Woods offers a refreshing change," she said, encouraging visitors to set aside their phones and take in a place that gives a firsthand look at how this area was originally settled and preserved.

What to Actually Do There Before the Leaves Turn

The designation is history, but the preserve is still an active calendar, and August 2026 has been a busy one. Earlier this month, on August 1, the district ran its annual Rubber Duck Race on Salt Creek, with ducks sold at $15 each, five for $60 or ten for $100, and a $500 first-place prize. Proceeds went to Friends of the Forest Preserve District of DuPage County. On August 6, a Forest Invaders walk taught adults to identify nonnative and invasive plant species by leaf, root and stem for $5 a person.

If you're planning something for this week, the next event on the calendar is the Family Evening Hike: Sounds of the Evening, running Friday, August 14, from 6:30 to 8 p.m. It's built for all ages, with kid-friendly stops and a take-home spotlight card, and costs $10 per family. Earlier programs this month included Little Explorers: Creek Critters for preschoolers and a Family Time at the Miller's House session over at Graue Mill, both priced at $5 per child. An Arts and Crafts for Adults sewing and embroidery session has also been on the district's August schedule.

None of this requires advance planning beyond checking the DuPage County Forest Preserve District's site for exact times, since programs like these tend to fill quickly and require registration. A few practical details worth knowing before you go: the preserve itself is open from one hour after sunrise to one hour after sunset, dogs are welcome on leashes no longer than 10 feet, and the Nature Education Center runs daily from 10 a.m. to 4 p.m. from mid-April through mid-November, shifting to a Monday through Saturday schedule the rest of the year. The center itself is at 3609 Spring Road in Oak Brook, with Graue Mill a short walk south at 3800 York Road.

The Loop You Already Know, Seen Differently

None of this changes what Fullersburg Woods is for most Hinsdale families: the default walk, the place you take a Sunday afternoon when you need forty-five minutes outside without getting in the car for long. What changes is what you're actually looking at. The stone shelter your kids used as a base for tag was built by a CCC crew during the Depression and just earned a federal designation for surviving nearly a century intact. The mill wheel that still turns has been protected since 1975. And the woods carrying a name from a town absorbed into Hinsdale more than a hundred years ago are, as of this June, officially recognized for exactly that history.

That's the kind of detail that doesn't show up on a trail map, but it's the reason a walk you've done fifty times can still hand you something new.
