Stand at the Bethelview Trailhead on Big Creek Greenway right now and you'll find orange construction fencing where the boardwalk used to carry you north toward Sawnee Mountain. Walk or bike from the south end, through Fowler Park, and you'll get most of the way there before the trail simply stops. This isn't a rumor passed around a neighborhood group. It's the current, on-the-ground state of Forsyth County's most-used trail, and it's splitting a fall season that usually belongs to one long ribbon of pavement into two separate outings.
What's interesting isn't that the trail is under construction. Trails get renovated. What's interesting is what's filling the gap while it happens. Cumming City Center's Lou Sobh Amphitheater has built its busiest run of free concerts in recent memory for exactly this stretch of September and into October, and the timing means a lot of Cumming residents who'd normally spend a Saturday evening on the greenway are instead finding their way to a lawn chair on Canton Road. That's not a coincidence worth ignoring. It says something about how this town actually spends its evenings when its main outdoor corridor isn't fully available.
Where the trail actually breaks
The greenway has been in some phase of closure for most of 2026, and the reasons have changed enough that it's worth separating them out. Back in late February, Forsyth County closed the stretch from Fowler Park to the Bethelview Trailhead for about two weeks to do geotechnical boring, the soil testing needed before installing the helical piers and Permatrac decking specified for the rebuild. That was step one of a much bigger project: a full redesign of the aging boardwalk sections, funded through a $33 million SPLOST IX allocation, meant to hold up better against the wetland conditions that have chewed through the original structure since it opened in 2009.
Then summer flooding added a second, unrelated problem. According to Forsyth County's own update, most of the greenway reopened on July 27 after the floodwaters receded, but a fallen tree had damaged the boardwalk just south of Bethelview, down to mile marker 8.1, and that stretch stayed shut for repair. Layer that on top of the renovation closure running from mile marker 8.3 north to 10.3, and you get a trail that's effectively broken in the middle at Bethelview itself, for two different reasons, on two different timelines.
Here's what that means if you're planning an actual walk or ride this month:
| Segment | Status | Cause |
|---|---|---|
| South county through Fowler Park to roughly mile marker 8.1 | Open | Reopened July 27 after flood cleanup |
| Bethelview Trailhead and mile markers 8.3–10.3 | Closed | Ongoing SPLOST IX boardwalk renovation |
| Mile marker 10.3 north to Sawnee Mountain Preserve | Open | Unaffected by either closure |
Add up the open sections and Forsyth County puts the usable trail at over 13 miles out of the full 16.5-mile run, which is most of it. The catch is that you can't currently do the whole thing as one continuous outing. You pick a side. The southern half gives you the shaded, forested miles through Fowler Park with its tennis courts and ball fields along the way. The northern half gets you the newer stretch out to the Sawnee Mountain Preserve Visitor Center on Spot Road, with hiking access to the Indian Seats trail once you're there. Both are worth doing. Neither connects to the other right now, and there's no firm reopening date yet for the renovation segment, since the county has said it will release a construction schedule once the design phase wraps.
The free calendar that picked this month to get busy
While the trail's middle sorts itself out, Cumming City Center has quietly built out one of its fullest concert calendars of the year, branded as the Fall Concert Series and presented by The Providence Group. All of it happens at the Lou Sobh Amphitheater, the covered band shell on Canton Road that overlooks the City Center's reflecting pond, and all of it is free.
The month has already delivered four of these nights. The Fixins opened things on September 4, an Atlanta rock outfit, and The Troubadour Project followed the next night. The Mad Hatters brought a Tom Petty tribute set to the amphitheater on September 11, and Elevation followed with a U2 tribute show on September 12. From here, the back half of the calendar is still ahead: Excitable takes on Def Leppard's catalog on September 19, Departure covers Journey on September 25, and the Radio 80s Band closes out the month on the 26th. The series then carries into October, with Pandora's Box covering Aerosmith on October 2 and NÜ Wave ATL closing the run on October 9 with 80s new wave.
None of it costs anything to walk into. Parking is free too. The rules are simple: no coolers, no outside food or drinks, no cans or glass, no smoking, and no tents, though a dog on a leash is welcome and a folding chair or blanket is exactly what you're supposed to bring. If you're planning to make a night of it, Lou Sobh Honda has also rolled out a free ride-home service for select 2026 shows, called Sobh Safe Rides, aimed squarely at people who'd rather not think about driving after a late set.
It's not just concert nights carrying the calendar, either. The City Center green hosts free Monday yoga at the amphitheater through October 26, a Friday morning fitness class at 8:30, and a Fall Market on September 19 that turns the same lawn into an artisan and vendor event during daylight hours. Even on the nights nothing is booked, there's enough recurring free programming that City Center functions less like an occasional event venue and more like a second town square with a set schedule.
Two systems, one fall
None of this is Cumming solving a trail problem with a concert series. The greenway renovation and the City Center calendar were planned on entirely separate tracks, by entirely separate parts of the county and city government. But the overlap this fall is worth noticing anyway, because it shows something about how this place is actually built now. Cumming has spent the last several years developing two distinct outdoor gathering systems at the same time, one a natural trail corridor stretching the length of the county, the other a compact, programmed plaza built around a single amphitheater. Most years, you'd barely notice they're two separate things, because both are usually available and most people default to whichever fits their evening.
This fall makes the split visible. With the greenway's middle segment down, more of that Friday-night instinct that used to head toward the trail is landing at City Center instead, and the calendar there happens to be full enough to absorb it without anyone feeling like they're settling for a backup plan. That's a fairly specific kind of town infrastructure to have built by accident: two systems, each capable of carrying the town's outdoor social life on its own, with enough redundancy that a months-long construction closure on one doesn't leave a hole in how people spend their evenings. It's the kind of thing you only notice living here, watching it play out one closed trailhead and one packed amphitheater lawn at a time.
If you're weighing a walk versus a concert this week, both halves of the greenway are worth the trip, and the September calendar at City Center is worth checking before you assume Friday night means nothing's going on. And if all this texture, the trail systems, the free concerts, the way this town keeps finding a second option when the first one's under repair, is part of what's making you think more seriously about a move here or a sale of your own place nearby, Watkins Real Estate Associates has been working South Metro Atlanta long enough to know which neighborhoods run like this one does. A free home valuation is a low-pressure way to find out what your timing actually looks like.
