Ask a longtime Williston resident what they do for Halloween and most will say the same thing: you go downtown for Trail of Treats. That answer has been true for over a decade. It is no longer complete.
In the last two years, two organizations that had never run October programming before have added their own events to the calendar, and neither one asks you to wait until Halloween night. Great Northern Events Center is hosting its second annual Oktoberfest on Saturday, October 24. The Williston Parks and Recreation District has scheduled a Floating Pumpkin Patch at the ARC on Thursday, October 29. Trail of Treats still closes out the month on its usual date, Saturday, October 31. What used to be a single evening downtown is now a run of three weekends, three organizers, and three different kinds of nights out, and if you're only planning around the one you already know, you're planning around a third of what's actually happening.
The tradition you already know
Trail of Treats is the Williston Downtowners Association's long-running Halloween event, and it earns its reputation. In recent years the event has drawn more than 4,000 kids downtown, with over 50 businesses signing up to hand out treats along a route that the city closes to traffic for the afternoon. It's a daytime, family-first event built around the same downtown blocks that host Summer Nights on Main and the Art & Wine Walk. Many businesses also participate in the Teal Pumpkin Project, offering non-food treats for kids with allergies or sensitivities, a detail that matters if you're bringing a group with mixed needs.
None of that has changed, and none of it needs to. What's changed is what sits on either side of it.
What didn't exist two Octobers ago
Great Northern Events Center, the historic downtown venue that already hosts Summer Nights on Main after-parties and Tuesday trivia nights, ran its first Oktoberfest in 2025. This year's is billed as the second annual, which tells you something useful: this is not yet a fixture with a decade of muscle memory behind it. It's a young event still finding its shape, scheduled for Saturday, October 24, with music from the MoonCats. If you've been to the venue for a wedding or a conference and never for a themed night out, this is the one to watch, because it's the kind of event that either becomes a permanent piece of the fall calendar or quietly fades, and right now nobody outside the venue knows which.
The Floating Pumpkin Patch is a different animal entirely. Williston Parks and Recreation District is running it at the ARC on Thursday, October 29, and the concept itself is worth explaining if you haven't encountered it: instead of walking a field to find a pumpkin, you step into the pool, where pumpkins float on the surface waiting to be picked. Once you've chosen one, you decorate it on site with supplies provided at the ARC, or take it home to finish later. It's paired on WPRD's Halloween lineup with Costumes on Ice, another indoor rec district event for families who want Halloween activities without a coat.
The practical difference matters more than the novelty. A traditional pumpkin patch means driving out of town, dressing for whatever the weather is doing, and walking a field. A floating pumpkin patch means driving across town to an indoor pool on a Thursday evening. For a family with young kids and a school night ahead, that's not a small distinction. It's the difference between an outing and an errand.
Reading the calendar in order
Lay the last two weekends of October 2026 out and the shape becomes obvious:
- Saturday, October 24: Great Northern Events Center's Oktoberfest, adults-oriented, live music, downtown venue
- Thursday, October 29: Floating Pumpkin Patch at the ARC, family and kids, indoor pool, Williston Parks and Recreation District
- Saturday, October 31: Trail of Treats, family daytime event, downtown streets closed, Williston Downtowners Association
Three different organizers, three different audiences, three different settings, none of them competing directly for the same night. That's worth noticing on its own. A few years ago, the honest answer to "what's happening for Halloween in Williston" was one event on one date. Now it's a sequence that starts a full week before Halloween and asks you to actually check a calendar instead of relying on memory.
Where Cottonwood Forest still fits
Cottonwood Forest remains the name most people reach for first when they think about fall in Williston, and for good reason. It's been running its pumpkin patch and haunted attraction for roughly a decade, long enough to become the default answer before the Downtowners or the parks district added anything new. If you've followed local news at all this year, you likely already know the property has been at the center of a zoning debate with the city, a separate story from what's covered here. What matters for weekend planning is simpler: it's still there, still seasonal, and still the option most people picture when someone says pumpkin patch. It just isn't the only option anymore, and for a Thursday night with young kids who don't want to bundle up for a field, the indoor alternative at the ARC might actually fit better.
What this means if you're planning your own October
If you want the event that's been part of Williston's identity the longest, Trail of Treats on October 31 is still the one to build your Halloween day around. If you're looking for something you haven't tried yet and don't mind an event still working out its footing, Great Northern's Oktoberfest on the 24th is worth a look, if only to see whether it becomes a fixture. And if you've got a household with young kids who'd rather not fight October wind for a corn maze, the Floating Pumpkin Patch at the ARC on the 29th solves a problem that didn't have a good local solution a few years back.
None of this requires leaving town, and none of it requires guessing. It requires checking three separate calendars instead of one, which is a strange kind of progress but progress all the same. Williston's fall used to be built around a single institution's programming. Now it's built around three organizations that don't coordinate with each other, which means the family that wants all three has to do the coordinating themselves.
That's the actual shift here, not a new pumpkin patch or a new venue booking a band, but the fact that Williston's October calendar has enough going on that residents now have to choose between events rather than simply showing up to the one that's always been there. Whether that becomes permanent depends on whether Great Northern's Oktoberfest sees a third year and whether the Floating Pumpkin Patch draws enough families to stay on WPRD's calendar past this season. For now, it's three weekends worth marking down, not one.
