You’ve probably driven past it a dozen times without even blinking. Located right at the intersection of Checker and Arlington Heights Roads in Long Grove, Buffalo Creek Forest Preserve doesn't exactly scream "epic wilderness" from the pavement. It looks like a flat stretch of grass. Maybe a few trees. But honestly? If you judge this place by its perimeter, you’re missing out on one of the most successful ecological engineering projects in the entire Chicago suburbs.
It’s huge. 408 acres huge.
For years, this land was basically just a giant sponge for the surrounding neighborhoods. It was functional, sure, but it wasn't exactly a destination. That changed. After a massive $9.5 million renovation project involving the Lake County Forest Preserve District and the Village of Buffalo Grove, the site was transformed from a simple drainage basin into a high-tier recreational spot. They didn't just plant some flowers and call it a day. They moved over 300,000 cubic yards of dirt to create better water storage and, more importantly for us, a killer trail system.
The Trails at Buffalo Creek Forest Preserve Are Different
Most people go to forest preserves expecting dense, dark woods. If that’s what you want, go to Ryerson. Buffalo Creek is all about the big sky. It’s an expansive, rolling prairie landscape that feels more like the Great Plains than the North Shore.
There are about 5.5 miles of gravel trails here. They’re wide. They’re well-maintained. They’re perfect for those days when the Illinois mud makes other trails impassable. Because it's so open, the wind can get a bit wild. If you’re biking against a headwind on the western loop, you’re going to feel it in your quads. Trust me.
The loops are interconnected, so you can customize your distance. If you’re just looking for a quick 20-minute power walk, stay on the smaller eastern segments. If you want the full experience, take the tunnel under Lake Cook Road. Yes, an actual tunnel. It connects the main preserve to the southern portion, and it makes the whole hike feel like a much larger adventure than it actually is.
Why the "Reservoir" Label Matters
You’ll see signs mentioning the "Buffalo Creek Reservoir." This isn’t just flavor text. The preserve serves a massive role in flood control for the Des Plaines River watershed. During heavy rains, the lower-lying areas are designed to hold millions of gallons of water. This protects homes downstream.
But for the average visitor, the reservoir means birds. Lots of them. Because there’s so much varying elevation and water levels, it’s a magnet for migratory species. You’ll see Great Blue Herons standing like statues in the tall grass. You might even spot a Snowy Owl if you’re lucky and the winter is harsh enough. Bring binoculars. Even if you aren't a "bird person," seeing a hawk dive into the prairie grass from fifty feet up is objectively cool.
Common Mistakes People Make When Visiting
Don't show up in July at 2:00 PM without water. I'm serious. Because the preserve is mostly restored prairie and wetland, there is almost zero shade on the trails. It is sun-drenched. In the middle of an Illinois summer, that gravel can radiate heat like an oven.
On the flip side, this lack of tree cover makes it the absolute best place for sunset watching. You get an unobstructed view of the horizon that you just can't find in the more wooded parts of Lake County.
- Parking: There are two main lots. Use the one on Checker Road for the easiest access to the big loops.
- Dogs: They’re allowed, but keep them on a leash. The rangers here don't mess around, and the local wildlife (coyotes included) is very active.
- Biking: It’s a favorite for gravel grinders. Just watch out for the walkers near the trailheads.
The Ecological Turnaround
Back in the 70s and 80s, this area was mostly farmland and deteriorating open space. The soil was tired. The biodiversity was low.
The Lake County Forest Preserve District experts—people who actually spend their lives studying soil acidity and seed dispersal—have done something incredible here. They’ve reintroduced native shortgrass and tallgrass species that would have been here 200 years ago. They do "prescribed burns" regularly. If you see charred ground in the spring, don't panic. It's intentional. Fire kills off invasive species and lets the native plants, which have incredibly deep root systems, thrive.
These roots are the secret. Some prairie plants have roots that go 15 feet deep. That’s why the preserve is so good at handling floods. It’s a living, breathing machine.
Is It Worth the Drive?
If you’re coming from the city, it’s a bit of a haul. But if you’re in the NW suburbs—Palatine, Arlington Heights, Wheeling—it’s a no-brainer. It’s rarely as crowded as Busse Woods or Independence Grove. You can actually find some silence here.
There’s a specific kind of peace that comes from being in the middle of a 400-acre field where you can’t see any cars, even though you know a Starbucks is only three minutes away. It’s that weird suburban liminal space where nature is winning for once.
Actionable Advice for Your Visit
- Check the Wind: Use a weather app. If gusts are over 15mph, the open prairie will be a struggle for casual bikers.
- Winter Prep: This is a premier spot for cross-country skiing because the trails are so wide and flat.
- Photography: Go during the "Golden Hour"—the hour before sunset. The way the light hits the tall grasses is a photographer's dream.
- The Lake Cook Road Tunnel: If you have kids, take them through the tunnel. It’s a small detail, but for a 5-year-old, it’s the highlight of the trip.
Start your hike at the Checker Road entrance and head west. Take the long loop around the reservoir first to get the "big" views out of the way. Then, as you head back toward the lot, use the smaller interior trails to cool down. If you’re feeling ambitious, cross under Lake Cook Road and explore the southern tip near the golf course. It’s a different vibe—more manicured but still peaceful. Pack a light snack, leave the headphones at home for once, and just listen to the wind in the grass. It's better than any podcast.
