Fairfax County Fall Festivals in 2026: Plan Your Weekends

Fairfax County did not ease into fall this year. It opened with a scramble.

On September 19, three fall festivals started on the same day in three different parts of the county, and none of them were close enough to combine into one outing. Cox Farms opened its Fall Festival in Centreville, a seven-week attraction that runs through November 8. George Washington's Mount Vernon opened its Colonial Market & Fair on the 12-acre field along the Potomac, a two-day event that wrapped up September 20. And Reston Town Square Park hosted the Reston Multicultural Festival, a single afternoon that came and went the same day it started. If you live in Fairfax County and wanted to do something fall-shaped last weekend, you had to pick a lane, because these three events sit on opposite ends of a county that stretches from the river in the southeast to the Bull Run Mountains in the west.

That was only the opening weekend. What's actually going on this fall is that Fairfax County's one-off festival calendar runs from September 19 through October 3. There is no long, leisurely run of one-off festivals to wander through. There is a front-loaded stretch of overlapping Saturdays, but that October 3 endpoint doesn't include ongoing attractions.

The Opening Weekend Wasn't Really a Choice Between Festivals

It was a choice between categories of fall.

Cox Farms is not a single-day event competing for your Saturday. It is a seven-week commitment. The Fall Festival opened September 19 and runs through November 8, with the farm shifting to a Thursday-through-Monday schedule starting September 26. Hours run 10 a.m. to 6 p.m. through October, dropping to 10 a.m. to 5 p.m. in November, with last entry an hour before close. Once you buy a ticket, you're choosing to return, possibly more than once, for the hayride, the Cornundrum corn maze, and the goat village that make it Northern Virginia's default answer to "where do we take the kids in October."

The Colonial Market & Fair, by contrast, only existed for 48 hours. Included with regular Mount Vernon admission (adults 12 and up paid $30, ages 6 to 11 paid $16, under 5 got in free), it turned the estate's 12-acre field into an 18th-century marketplace with artisans demonstrating period ceramics, glasswork, and woodcraft. If you missed it, there's no second chance this year. It already happened.

The Reston Multicultural Festival was even more compressed: one afternoon, one park, free to attend, built around the performances, food, and community organizations that reflect Reston's demographic makeup. Also already over.

So on the exact same Saturday, a Fairfax County household had to decide between starting a season-long ritual at Cox Farms, catching a two-day heritage market that would be gone by Sunday night, or showing up for a single free afternoon in Reston that had no rain date. That's not really a menu of festival options. It's three different definitions of what "doing fall" means, and they all opened on the same 24 hours.

This Weekend Splits the County Again, By Age and By Access

The pattern repeats September 26 and 27, but the fault line shifts from geography to audience.

Mosaic District in Merrifield is hosting its Fall Fest in partnership with URBNmarket and FreshFarm, bringing more than 140 local makers to District Avenue for a two-day outdoor market running 11 a.m. to 6 p.m. both days. It's free to attend, parking is free in the garages, and there's a complimentary shuttle running every 20 minutes from the Dunn Loring Metro station. If you don't own a car or just don't want to deal with festival parking, this is the one weekend event in the entire lineup built around not needing to drive.

The Winery at Bull Run, also in Centreville, just a short drive from Cox Farms, is running its Fall 2026 Bull Run Wine Festival the same weekend. General admission runs $48, the event is strictly 21 and older, and it runs noon to 5 p.m. both days with wine tastings from Virginia vineyards, a featured brewery, food trucks, and live music on Hillwood Lawn. Guests under 21, including infants, aren't permitted in the festival area at all.

That means Centreville hosts two fall festivals within the same three-week span that could not be more different: one is a family farm attraction with a goat village and a corn maze, the other is a ticketed, adults-only wine event with a $48 cover charge. Same town, same season, two audiences that will likely never overlap.

The One-Off Calendar's Final Saturday Stands Alone

After the opening rush, the one-off calendar has another overlapping weekend on September 26 and 27, then closes with a standalone event on October 3.

Vienna Oktoberfest takes over historic Church Street on October 3, running 11 a.m. to 7 p.m. with beer and wine gardens, multiple stages of live music, a vendor marketplace, and a dedicated Kids Zone. Admission is free, which sets it apart from both the ticketed Cox Farms entry and the $48 wine festival the weekend before.

What This Means If You're Trying to Do More Than One

Here's the practical shape of the next three weeks, laid out by date:

A few things fall out of this once you see it laid flat. First, the Colonial Market & Fair and the Reston Multicultural Festival from the opening weekend are already over by the time you're reading this on September 24. Second, the two events that overlap on cost and audience, the free Reston festival and the free Vienna Oktoberfest, are two weeks apart, so there's no actual conflict there. Third, the real planning problem isn't spacing, it's Centreville, which hosts both a family farm attraction that runs for seven weeks and a 21-and-over wine festival within the same three-week stretch, meaning anyone trying to bring both a toddler and a designated driver's night out into the same season needs to treat those as two separate trips, not one.

The Takeaway for Anyone Who Lives Here

Fairfax County's one-off fall festival lineup isn't a slow build from pumpkin spice to peak foliage. It's a compressed, three-weekend sprint that opened with an actual three-way conflict, splits again this weekend along an age and access line in the same town, and closes with Vienna Oktoberfest on October 3. If you're mapping out the next few weekends, the smart move is picking one event per weekend rather than assuming you can string several together, because the geography and the calendar are both working against a leisurely tour.

That kind of local rhythm, knowing which weekends compete with each other and which parts of the county quietly run their own calendar, is the same instinct that matters when you're reading a neighborhood's housing market instead of its festival lineup.
