Drive LaGrange Road past 167th Street on any weekday and you'll pass the same landmarks everyone in Orland Park uses to give directions: the mall traffic, the strip retail, the steady churn of cars turning into parking lots. What most of those drivers don't know is that less than a quarter mile west, behind the last row of stores, sits 960 acres of restored tallgrass prairie that didn't exist in its current form twenty-four years ago. It was farmland. Before that, hayfields the Forest Preserve District leased out through 2003. Today it's one of the better grassland bird sites in Cook County, and it's sitting there mostly empty on a Saturday morning while the parking lots a quarter mile away fill up.
That's the thing worth knowing about Orland Grassland. It isn't old growth, and it isn't wilderness in the untouched sense. It's a deliberate, still-ongoing rebuild, and understanding that changes how you use it.
The Land Was a Hayfield Until 2003
The Forest Preserve District of Cook County bought this land in the 1960s, a stretch running from 167th Street to 179th Street and from LaGrange Road to 104th Avenue, and called it the Orland Tract. For decades it functioned as leased farmland. Farmers hayed the interior grasses right up until 2003, which means the prairie you'd walk through today is younger than most of the subdivisions around it.
The restoration effort that changed that began in 2002, when the district committed to what became one of the largest land restoration programs in its history. Openlands, the Army Corps of Engineers' Chicago Region office, and the Forest Preserve District put roughly $7.7 million into the work: removing woody invasive growth, planting more than 100 species of native prairie plants, rebuilding wetland pockets that farming had drained. Much of the site is now enrolled in the Illinois Nature Preserve system, and it carries an Important Bird Area designation.
None of that shows up from LaGrange Road. From the outside it still just looks like open field behind a retail corridor. That mismatch between what the site looks like and what it actually is turns out to be most of the reason so few residents have walked it.
Two Trails, Two Very Different Walks
Orland Grassland isn't one loop. It's really two units connected by trail, and which one you pick changes the walk.
- The main unit has a five-mile paved trail ringing the perimeter, flat, wide, and suited to strollers or a bike if you'd rather cover ground than stop and look.
- The south unit, adjacent to the main tract, has its own 1.6-mile paved loop, a shorter option if you're working around a nap schedule or just want thirty minutes outside.
- Unpaved interior trails, including the stretch locals call the Birdsong Trail, cut through the restoration areas themselves rather than skirting them. These are marked with handmade signs put up by Cub Scout Troop 372 out of Orland Park, and they're where you actually get inside the prairie instead of walking its edge.
If you've only ever driven past, you've seen the tree line ringing the property and assumed that's all there is. The interior trails are where the site earns the acreage.
The Birds That Don't Show Up in Any Wooded Preserve Nearby
Here's the part most people miss, including some residents who do walk the paved loop regularly. Orland Grassland's value isn't generic nature. It's specifically grassland habitat, and that's a different thing from the wooded forest preserves scattered around the south suburbs.
Grassland-obligate birds, meaning species that need open prairie and won't nest in woodlots or backyard tree cover, have been losing habitat across Illinois for a century. Orland Grassland's restored acreage gives them a place other nearby preserves can't. Bobolinks, Dickcissels, Eastern Meadowlarks, and Henslow's Sparrows all breed here. So do Grasshopper Sparrows and Field Sparrows. In the wetland pockets scattered through the site, you'll find Virginia Rail, Sora, and Wilson's Snipe. Bell's Vireos and Yellow-breasted Chats work the shrubland edges.
In 2016, the Forest Preserve District ran a friendly competition among its sites called Bird the Preserves. Out of 21 locations across the entire county, Orland Grassland finished second, with 194 species recorded over the year, behind only Busse Woods, which is roughly three times the size and has decades more established habitat. For a site whose interior restoration was barely fifteen years old at that point, that's not a modest result. It's the clearest evidence that the rebuild worked.
The Month Nobody Puts on the Calendar
Most people who think about birding in Illinois think spring migration, the few weeks in May when warblers pass through and every preserve fills with binoculars. Orland Grassland benefits from that traffic too, but its actual specialty runs later. Grassland breeders don't pass through and leave. They arrive in late spring and stay to nest, which means the best window for seeing Bobolinks doing their tumbling flight display, or hearing a Henslow's Sparrow's short insect-like call from deep in the grass, runs from May into July. That's exactly the stretch when most casual walkers have moved on from thinking about birding at all.
The Chicago Bird Alliance, formerly the Chicago Audubon Society, runs guided walks here timed to that window. One scheduled for May 2026 met at the parking lot on 167th Street specifically to target returning breeding species, Bobolinks, Dickcissels, and meadowlarks among them, with sparrows including Henslow's, Field, and Grasshopper also expected. The trip filled and closed to new registrants, which tells you something about who already knows this site is worth the early wakeup.
Who Keeps 750 Acres From Reverting to Brush
Restored prairie doesn't stay restored on its own. Left alone, invasive brush and volunteer trees creep back in within a few seasons, which is exactly what had started happening to the original Orland Tract before residents intervened. A volunteer group organized in the early 2000s, persuaded the district to formally rename the site from Orland Tract to Orland Grassland, and has run recurring workdays ever since, clearing invasive growth, maintaining the interior trail signage, and coordinating with the district on prescribed burns that keep the prairie ecosystem functioning the way fire historically did before European settlement.
That volunteer layer is worth knowing about if you're the kind of resident who likes understanding how a place actually gets maintained, not just what it looks like on a nice day. The Orland Grassland Volunteers group still holds quarterly meetings at the Orland Park Civic Center and organizes seasonal work.
Getting There Without Guessing
The main access point sits at 9700 W 167th Street, a parking lot just west of LaGrange Road. It's an easy address to underestimate on a map because it reads like any other suburban lot, but it puts you directly at the trailhead for both the paved perimeter loop and the unpaved interior trails. The south unit's 1.6-mile loop is reachable from the same general area. Bring insect repellent in summer. The paved sections handle strollers and bikes without issue, but if you want the Birdsong Trail experience, plan for uneven ground and the kind of shoes you don't mind getting a little dusty.
There's a particular kind of local knowledge that comes from knowing a place isn't what it looks like from the road. Most of Orland Park drives past this prairie on the way to Target without a second glance. The residents who've actually walked it tend to be the ones who know the village in a way that doesn't show up on any listing sheet, the ones who can tell you which corner of town still surprises people who've lived here twenty years.
That kind of granular, walked-it-myself familiarity with Orland Park is the same thing I bring to conversations about buying or selling here. If you're weighing a move in this village, or just curious what your own corner of it is actually worth these days, I'd rather talk specifics than generalities. Reach out to Aaron Gaines when you're ready for that conversation.
