Drive down Sellers Avenue in the last week of August and the cherry stand at G&S Farms is dark. The 2026 cherry U-pick closed weeks ago, the short season that usually opens in early May and wraps by mid-June having run its course months before most people think about fall. A quarter mile away, the same farm's fruit stand is still stacked with sweet corn and cannery tomatoes, the crop that took over the moment the cherry trees emptied out.
Ten minutes east, at the corner of Marsh Creek and Vasco roads, Three Nunns Farm already lists its pumpkin patch as open for the season. Not a typo, and not decorative gourds waiting for October. The farm's own posted window for pumpkin picking runs August through September, weeks before Smith Family Farm's Pumpkin Harvest even opens and more than a month before the corn maze crowd shows up anywhere else in town.
This is the thing about Brentwood's farm trail that a single "visit the pumpkin patches" post never quite captures: the season doesn't turn over on one date. It rolls through in overlapping waves, timed to each grower's own crop, and if you're waiting for the whole town to feel like fall at once, you'll miss the early movers and show up too late for the ones that wait until October.
The Signs That Already Flipped
Cherries are the shortest window on the calendar, and by late August, that window has already closed at the stands that count on it most. G&S Farms, the family operation that has grown Brentwood cherries for three generations, posted its 2026 cherry U-pick as closed with a thank you to the season already behind it. Marsh Creek Cherries, on its 40-acre spread at Orchard Lane and Concord Avenue, closed for the 2026 season too. Dwelley Family Farms, the only certified organic cherry U-pick in the area, runs its own short window each spring across its TK's Ranch and Suzuki locations, the same early window that closes every other cherry farm in town by early summer.
None of that is unusual. Cherry season here typically opens in early May and is largely finished by mid-June, weather dependent. What it means right now is simple: if cherries were the reason you were planning a farm trip, that door closed months ago, and the next one on the calendar hasn't opened yet.
The Stand That Never Actually Closes
What has not closed is the produce that fills the gap between cherry season and pumpkin season. Smith Family Farm, at 4350 Sellers Avenue, runs its fruit stand daily from spring through the beginning of December, and right now that stand is stocked with tomatoes, Brentwood corn, peppers and chiles, summer squash, Bartlett pears, and the tail end of stone fruit season. The farm has sold produce out of that stand for more than three decades, and late August is one of its busiest stretches precisely because so many crops are peaking at once.
Even that window has an expiration date. Brentwood's signature Super Sweet corn, the crop the city is best known for, typically runs from late May or early June through Labor Day weekend, according to one longtime area grower. That means the corn on the stand right now is closer to its last few weeks than its first.
The Farm That Didn't Wait for October
Here's the detail most visitors miss because they're comparing farm websites one at a time instead of side by side. Three Nunns Farm markets its pumpkin patch as an August-through-September activity on its own site, distinct from the October-only openings everywhere else in Brentwood. If you want the first pumpkin picking of the year in this town, Three Nunns is very likely your earliest option, running daily from 10 a.m. to 6 p.m. through October 31.
Compare that to Smith Family Farm, whose Pumpkin Harvest and Tomato Day open September 26, or Harvest Fields Corn Maze & Hayride, which doesn't run at all until October 9. Three farms, three different starting lines, and none of them share a calendar.
| Farm | What's happening in late August 2026 | What opens next |
|---|---|---|
| G&S Farms | Cherry U-pick closed for the season | Corn maze and live-vine pumpkin U-pick open in October |
| Smith Family Farm | Daily fruit stand: tomatoes, corn, peppers, stone fruit | Pumpkin Harvest and Tomato Day open September 26 |
| Three Nunns Farm | Pumpkin patch already running per the farm's own August–September window | Open daily through October 31 |
| Harvest Fields Corn Maze & Hayride | Not yet open | Corn maze and hayride run October 9–24, evenings only |
Two Different Corn Mazes, Not One
The bigger surprise is that "the Brentwood corn maze" isn't one experience. It's at least two, and they serve different crowds.
Smith Family Farm's version runs during the day, 9 a.m. to 5 p.m., alongside live music, animal encounters, a sunflower forest, and an herb garden labyrinth. It's built for strollers and younger kids, the kind of outing where a toddler can nap in the car on the way home. Three Nunns runs on a similar daytime schedule, 10 a.m. to 6 p.m. daily through the end of October, with its own corn maze and pumpkin patch layered into the visit.
Harvest Fields Corn Maze & Hayride is a different animal entirely. It runs Friday and Saturday nights only, 7 p.m. to 11 p.m., October 9 through 24, and the admission covers unlimited maze runs, a hayride, a hay fort, round bale racers, duck races, cornhole, and a corn cannon that costs a dollar for two shots at a pumpkin target. That's not a stroller outing. That's a nighttime event built for older kids, teenagers, and couples looking for a fall date that isn't dinner and a movie.
So the question isn't just when the corn maze opens. It's which corn maze, because the daytime, animal-and-live-music version and the nighttime, hayride-and-games version aren't competing for the same evening, and they're not even open in the same month.
Reading the Trail Instead of Waiting for a Sign
Part of why this staggers the way it does is that farms here don't run on a shared publicity calendar. Each one posts its own hours, and several don't lock in exact fall dates until close to the opening weekend. The practical move, if you actually live here and want to time a visit right, is to check the individual farm rather than assume the whole trail moves together. Harvest Time in Brentwood, the nonprofit that has tracked local agritourism for years, keeps a running farm status page and produces an annual trail map covering more than 65 growers who sell direct to the public. It's the closest thing this town has to a single source of truth for what's actually open this week.
The Brentwood Farmers' Market, on First Street every Saturday from 8 a.m. to noon, year-round, is another useful pulse check. Vendor lineups shift weekly with whatever's actually ready to sell, which makes it a faster read on the season than any single farm's website.
Why the Trail Matters Beyond the Pumpkins
This staggered, farm-by-farm calendar isn't an accident. It's a byproduct of how much working farmland still sits inside city limits here, close enough to newer subdivisions that the city's Right-to-Farm ordinance shows up on disclosures for homes built at the edge of it. The same fields that give Brentwood its early-August tomatoes and late-September pumpkins are also why living near them comes with a different kind of neighbor than a typical suburban block, one that runs on planting and harvest schedules instead of a homeowners association calendar.
For anyone who already calls Brentwood home, that rhythm is part of what the town actually feels like day to day, long after the last corn maze closes for the year. If you're weighing whether that rhythm fits the way you want to live, or you're comparing what a home near this farmland actually looks like on paper, the team at The Lucas Group knows this stretch of the East Bay from the ground up.
