Glencoe Has Three Trails. Most People Only Ever Walk One.

Ask a longtime Glencoe resident where the North Branch Trail goes and they'll tell you it dead-ends somewhere near the Botanic Garden. Ask about the Green Bay Trail and they'll describe the spine that runs past downtown toward Highland Park. Ask about the two together and most people pause. They've walked both. They've just never walked them as one thing.

That's the part worth knowing before the leaves turn: they are one thing. A one-mile stretch through the Chicago Botanic Garden's own grounds is the hinge that makes the North Branch and Green Bay trails into a single loop, and it's been sitting there the whole time, mostly unused by the people who live closest to it.

The Two Trails Everyone Already Knows

The North Branch Trail is the one most Glencoe residents picture first: a paved bicycle trail that runs 20 miles from Devon Avenue in Chicago north to Dundee Road, right at Glencoe's edge. For a lot of people that's where the mental map stops. Dundee Road feels like an ending, the point where the trail becomes somebody else's errand.

The Green Bay Trail is the second one, and it's the trail most residents actually use day to day. It's a 10-mile mix of paved and crushed limestone path that starts in Wilmette and runs north through Glencoe's own downtown before connecting into Lake County's trail system. If you've walked to the train station, to Guildhall for dinner, or past Writers Theatre on a Friday evening in summer, you've been on it.

What almost nobody treats as connected is the piece between them.

The Mile Nobody Talks About

The Chicago Botanic Garden built a one-mile multiuse path that links the Green Bay Trail to the North Branch Trail, cutting through the Garden's own McDonald Woods and continuing into Turnbull Woods, part of the Forest Preserves of Cook County. The Garden did this in partnership with the Illinois Department of Transportation and the Forest Preserves, and it's dotted with interpretive signage calling out the moraine, wetland, and woodland zones you're walking through, the same ecological patchwork that gives the Skokie Lagoons system its name.

On the east end, that connector meets the Green Bay Trail right at the Braeside Metra station on the Union Pacific North Line. On the west end, it feeds into the North Branch Trail as it continues past Dundee Road. In other words, the trail doesn't end at Dundee Road at all. It just changes its name and slips through the Garden on the way to becoming something else.

Most Glencoe residents have walked half of this loop a hundred times and the other half never, simply because nobody ever told them the two halves touch.

What the Loop Actually Feels Like

Start at the Braeside Metra platform, which sits close enough to the Garden that you could walk from the train to the trailhead without checking a map. Head west and you're immediately inside Garden property, moving through McDonald Woods before the path narrows into Turnbull Woods, where the Forest Preserves signage takes over and the noise of Green Bay Road disappears behind you. The path continues on to meet the North Branch Trail, and from there you can go as far south as Dundee Road takes you or turn back the way you came.

None of this requires a car. It doesn't require planning around traffic on Green Bay Road, or driving to a trailhead outside town. It requires knowing that the pieces line up, and most of the people who'd benefit most from that knowledge, longtime residents who've made peace with two separate trail systems, are the ones least likely to have looked it up.

Why This Is the Week to Walk It

Fall is when the reasons to actually make this walk stack up in the same three-week window. The Chicago Botanic Garden's calendar puts three separate draws right along the route this October:

• October 2 to 4: The Woman's Board of the Chicago Horticultural Society hosts its annual Fall Bazaar at the Garden, timed for the same weekend the connector trail is at its most walkable, cool mornings, dry leaves, no summer humidity.
• October 7 to 25: Night of 1,000 Jack-o'-Lanterns runs most evenings from 6:30 to 10:30 p.m., with roughly 75 giant pumpkins weighing about 150 pounds each carved and lit along a path through the Garden. It's an evening event, which means the same connector trail that's a quiet morning walk in daylight becomes a lantern-lit route after dark for a few weeks a year.
• All month: the Village of Glencoe co-sponsors its own Halloween Hello with the Winnetka-Northfield-Glencoe Chamber of Commerce and the Glencoe Historical Society, giving downtown its own October draw to bookend the Garden's.

None of these events require the trail to reach them. But the residents who already know the connector exists get to arrive at the Fall Bazaar or the Jack-o'-Lanterns walk on foot, coming out of Turnbull Woods rather than circling for street parking on Lake Cook Road.

Where It Starts and Ends

Downtown Glencoe is small enough that the loop's natural bookends are a five-minute walk from each other. Hometown Coffee & Juice makes sense as a start, something to carry the first stretch of the Green Bay Trail. Guildhall works as the other end, close enough to the Green Bay Trail that walking there after a loop through the Garden barely adds distance. And the Jeanne Gang-designed Writers Theatre sits in the same few blocks, which is part of why downtown functions the way it does: a small commercial core with a coffee shop, a restaurant, and a piece of notable architecture all within sight of each other, then trail access on either side of town.

This is also, not coincidentally, the same handful of blocks Hollywood found useful decades ago. Glencoe stood in for scenes in Ferris Bueller's Day Off, Sixteen Candles, and Uncle Buck, and the beach and downtown that made it onto film are largely the same ones still functioning as the town's center today.

The Thing Worth Knowing Before October Ends

The point isn't that Glencoe has good trails. Plenty of North Shore towns do. The point is that most residents are treating a connected system as three disconnected errands, and the missing piece isn't hidden. It's built, signed, and maintained by the Garden itself, sitting exactly where the two trails everyone already knows happen to meet.

That kind of detail, the way a town's public infrastructure quietly rewards the people who take the time to actually learn it, is part of what makes a neighborhood feel different to live in than it does to visit. It's also the kind of thing I find myself explaining to buyers who've decided they want the North Shore but haven't yet figured out which town fits how they actually want to spend a Saturday. If you're weighing that question, or thinking about what your own home here is worth in a market that rewards exactly this kind of neighborhood knowledge, I'd welcome the conversation.
