"We began in 1970 as a local festival to promote the city of St. Charles," festival chairman Mark Stubblefield said of the Festival of the Little Hills, which now spans more than half a century of continuous run. That festival returns to Main Street and Frontier Park August 21 through 23 this year. Five weeks later, on September 25, a much younger tradition takes over the same riverfront: the Saint Charles Oktoberfest, marking its 40th anniversary. And wedged in between, on September 19, a wine festival that is only entering its third year sets up two miles away in Frenchtown.
Most write-ups about St. Charles treat the fall calendar as a single, undifferentiated list of things happening on Main Street. That flattens the more interesting fact: this isn't one festival repeating four times. It's four events at four completely different stages of life, in three separate parts of the same city, and knowing which is which changes how you actually spend the weekend.
Three Neighborhoods, Not One Street
Ask most residents where "the St. Charles festivals" happen and they will say Main Street. That's true for two of the four weekends. The other two happen somewhere else entirely, and the distinction matters if you're trying to figure out where to park.
| Weekend | Event | Where | What's different about it |
|---|---|---|---|
| Aug 21-23 | Festival of the Little Hills | Historic Main Street & Frontier Park | The oldest, largest, most craft-focused |
| Sept 11-13 | MOSAICS Fine Art Festival | North Main Street | Juried fine art, not crafts |
| Sept 12 & 19 | Apple Festival / St. Charles Wine Festival | Saint Charles Market, Frenchtown | Food and drink festivals, not vendor fairs |
| Sept 20 | Saint Charles Fair | Blanchette Park | Carnival games and family contests, inland from the river |
| Sept 25-27 | Saint Charles Oktoberfest | Frontier Park | Beer, brass bands, a timed race |
Main Street and Frontier Park handle the big three: Little Hills, MOSAICS, and Oktoberfest. Frenchtown, the older residential grid along North Second Street, hosts its own Saturday market series, and that market is where the Apple Festival and the Wine Festival live. Blanchette Park, set back from the riverfront proper, is where the Saint Charles Fair happens, and it reads more like a county fair than a downtown festival: carnival games, face painting, pony rides, a petting zoo.
If you only ever go to Main Street, you're seeing maybe half of what the city actually programs between late August and late September.
Where the Half-Mile Doubles as a Museum
Little Hills isn't just old. It's specific about what it's preserving. The name itself comes from Les Petites Côtes, what French Canadian explorer Louis Blanchette called the settlement he founded in 1769, before it became St. Charles. The festival that carries that name has run every August since 1971, which puts this year's edition well past its 50th anniversary.
The 2026 lineup keeps the historical framing literal. Alongside the more than 300 arts and crafts vendors lining Main Street and spilling into Frontier Park, there's a Lewis and Clark encampment, a keelboat showcase, working blacksmiths, and Daniel and Rebecca Boone impersonators walking the grounds. Two stages in Frontier Park carry the entertainment through the weekend, and most of the food and drink booths are run by local nonprofits, whose proceeds fund at least five annual scholarships for St. Charles high school seniors.
The logistics are worth knowing before you go. Free parking is available along Riverside Drive, in the lot at Riverside and First Capitol, at the Lewis and Clark Boat House and Museum lot, and in the City Hall parking garage. Free shuttles run from Duchesne High School, St. Charles West High School, and EPC on the edge of downtown. Given that the festival draws visitors from well beyond the metro, arriving without a plan for parking means arriving late.
The Boundary Your Dog Needs to Know
Here's the detail that only matters if you actually live nearby and walk this stretch of river regularly: Frontier Park sits directly beside the Katy Trail State Park trailhead, and during Little Hills weekend, pets are welcome on the trail but not inside the park itself. If your normal Saturday route takes you and a dog down the riverfront path and back through the park, festival weekend is the one time of year that route gets interrupted partway through. The trail keeps its year-round rules. The park temporarily doesn't.
The Newcomer Still Finding Its Footing
The St. Charles Wine Festival, held in Frenchtown on September 19, is only in its third year. That puts it in a different category entirely from Little Hills or Oktoberfest. It's still building its identity: an evening of wine tasting, music, and live art demonstrations, set in the same market space that hosts the neighborhood's regular Saturday vendors.
A week earlier, on September 12, that same market space hosts the Apple Festival, with an apple pie contest and kids' activities layered onto the regular Saturday market rhythm. Together, the two events suggest Frenchtown is quietly becoming its own festival corridor, distinct from Main Street's arts-and-crafts identity and Blanchette Park's family-fair identity. It's smaller and newer, but it's not incidental.
Where the Family Day Actually Happens
If Main Street is about browsing vendor booths and Frenchtown is about food and drink, Blanchette Park is where the more traditional county fair energy lives. The Saint Charles Fair runs September 20, 11 a.m. to 5 p.m., with carnival games, a petting zoo, pony rides, and a lineup of contests that reads like it was written for a small town rather than a metro suburb: a Donut on a String Competition at midday, live music from the Riverbend Bluegrass Band in the early afternoon, and a Homemade Cream Pie Competition before the closing magic show.
That same Sunday, Pedal the Cause holds its charity cycling ride through the city, a reminder that not everything on the September calendar is a craft fair or a beer garden. Two very different kinds of gatherings, both drawing crowds to the same weekend, in two different parts of town.
Forty Years of Oompah
Oktoberfest closes out the run on September 25 through 27, and this year's edition is its 40th, dating back to 1986. The anniversary framing leans into tradition: oompah bands, bratwurst, funnel cakes, and multiple stages of live entertainment across Frontier Park. Sunday morning adds a structured event to the weekend's otherwise loose programming, the 15th annual Oktoberfest 5K and 10K, with every finisher receiving a medal and a themed shirt. For anyone who wants a lower-stakes way to participate, there's also the Wiener Dog Derby, which is exactly what it sounds like.
Forty years is a long run for a themed festival, and it shows in how established the format is. Compare that to the Wine Festival's third year, or even MOSAICS' more recent arrival on the calendar, and the age spread across just five weeks becomes the real story. This half-mile of riverfront isn't preserved as a monument to one era. It's still actively adding new traditions next to fifty-year-old ones.
The One New Name Worth Knowing in O'Fallon
Festival season isn't the only thing changing this year for residents of the broader St. Charles, Dardenne Prairie, and O'Fallon area. In O'Fallon, Interruption Public House & Brewery took over the former Good News Brewing space this year, with co-owner Donnie Cochran describing the run-up to opening in characteristically low-key terms: "We're so mentally ready to open." The brewery's roots go back to home brewing that started in 2018, grew through a homebrew competition at Good News, and eventually outgrew a one-barrel system and a single tap. The initial menu leans into wood-fired pizza and sandwiches built to complement the beer rather than compete with it.
It's a small addition compared to a 300-vendor arts festival, but it's the kind of local detail that tells you something real: this part of St. Charles County isn't just hosting the same festivals every year. It's also where new, smaller things are still getting started, one converted brewery space or one third-annual wine festival at a time.
If you're weighing what a neighborhood like this actually offers day to day, beyond the festival calendar, that's exactly the kind of on-the-ground read Kim Jones brings to every conversation about this part of West and St. Charles County.
