October is one of the best months to explore Northern Virginia and Washington DC. Cooler weather, changing leaves, fall festivals, Halloween attractions, wine events, live music, and family activities fill the calendar from the first weekend through Halloween. Whether you want a day at Cox Farms, a community festival in Fairfax or Vienna, or an afternoon exploring Washington DC, there is no shortage of things to do. If all that exploring has you thinking about where you want to live, browse Northern Virginia homes for sale or explore Team DDA's Northern Virginia area guides.

Cox Farms Fall Festival in Centreville

Throughout October

It would be difficult to make an October guide to Northern Virginia without including Cox Farms Fall Festival.

The Centreville tradition features its famous hayride, giant slides, farm animals, Cornundrum adventure, hay tunnels, seasonal food, pumpkins, and plenty of activities for families. The 2026 festival continues through November 8.

For visitors looking for something scarier, Fields of Fear transforms the farm after dark with haunted attractions geared toward older guests.

October weekends can get extremely busy, so advance tickets are a good idea.

Vienna Oktoberfest

October 3

Historic Church Street becomes one of Northern Virginia's biggest fall celebrations during Vienna Oktoberfest.

The free festival runs from 11 a.m. to 7 p.m. and includes three stages of live entertainment, beer and wine, international food, vendors, and free children's activities.

The setting around downtown Vienna gives the event a true neighborhood festival feel and makes it one of the easiest October events to enjoy with both adults and children.

Fall for the Book Festival

October 5 through 10

Readers should add the Fall for the Book Festival to the calendar.

The literary festival brings authors, readers, discussions, and special programming to George Mason University and other venues throughout the region. Visit Fairfax lists the festival among Fairfax County's major October events.

It is a good change of pace from the pumpkin patches and outdoor festivals that dominate much of the month.

Mount Vernon Fall Wine Festival and Sunset Tour

October 9 through 11

Few locations around Northern Virginia look better in October than George Washington's Mount Vernon.

The annual Fall Wine Festival and Sunset Tour gives guests an opportunity to sample Virginia wines while relaxing on the east lawn overlooking the Potomac River. Visitors can also explore parts of the historic estate during the evening experience.

This is one of the better October date night options for adults who want something more relaxed than a large street festival.

City of Fairfax Fall Festival

October 10

The City of Fairfax Fall Festival celebrates its 50th year in 2026.

More than 400 art, craft, information, and food vendors will fill downtown Fairfax along with children's activities, entertainment stages, and beer gardens. Admission is free.

The event runs from 10 a.m. to 5 p.m. and free shuttle service is available from designated parking locations.

For a classic Northern Virginia community festival with food, shopping, live entertainment, and activities for children, this is one of the biggest events of October.

ROCKtoberfest at Reston Town Center

October 10

Live music takes over Reston Town Center for ROCKtoberfest.

The 2026 event combines craft beer and rock music with Vertical Horizon as the featured headliner. Visit Fairfax also highlights the event as one of the county's major October festivals.

Because it takes place at Reston Town Center, visitors can easily combine the event with dinner, shopping, or an evening out.

Clifton Day Festival

October 11

Historic Clifton may be one of the most picturesque places in Northern Virginia during fall, and Clifton Day Festival is one of the best times to visit.

The festival includes hundreds of artisans, live music, children's activities, pony rides, food, antiques, and a beer and wine garden.

The historic streets, mature trees, local restaurants, and small town atmosphere make Clifton Day feel different from the larger shopping center and city festivals around the region.

Centreville Day

October 17

Centreville Day celebrates the Centreville community with food, entertainment, art, rides, local organizations, and family activities.

The 2026 festival takes place at Historic Centreville Park and runs from 10 a.m. to 4 p.m.

It is a good local alternative for families who want a community festival without traveling far into Fairfax or Washington DC.

Air & Scare at the Udvar Hazy Center

October 24

Halloween arrives early at the Steven F. Udvar Hazy Center in Chantilly.

The Smithsonian's annual Air & Scare event includes trick or treat stations, crafts, spooky science experiments, stories, photo opportunities, and a costume fashion show.

The family friendly event is free, although free tickets are required for the outdoor portion and parking is $15.

Having Halloween activities surrounded by aircraft and spacecraft makes this one of the most distinctive family events of the month.

Mount Vernon Fall Harvest Festival

October 24 and 25

Return to Mount Vernon later in the month for the Fall Harvest Festival.

The event demonstrates how harvest season looked during the 18th century, with activities involving cooking, wheat treading, spinning, textile making, horseshoeing, fresh bread, and other historic trades.

For families interested in history, it offers something very different from a modern fall carnival.

Halloween Fun Around Fairfax County

Fairfax County has plenty of ways to celebrate Halloween beyond traditional neighborhood trick or treating.

For serious scares, Cox Farms Fields of Fear offers evening haunted attractions, while the Workhouse Arts Center hosts its annual haunted experience at the historic former prison site in Lorton.

Families can also head back to Mount Vernon on Halloween for Trick or Treating at Mount Vernon, which includes candy collecting, a costume parade, historic entertainment, music, and seasonal activities from 2 p.m. to 5 p.m.

October Events Worth the Trip Into Washington DC

One of the advantages of living in Northern Virginia is having the District's October calendar within easy reach.

Snallygaster

October 10

Craft beer fans can head to Snallygaster on Pennsylvania Avenue.

The 2026 festival features at least 450 beers from 166 American and international producers along with food, live music, wine, cocktails, and other entertainment.

Destination DC lists the event along Pennsylvania Avenue between Third and Seventh Streets NW, making Metro one of the easiest ways to attend.

Theatre Week

Through October 11

Theatre Week runs from September 24 through October 11 and provides discounted access to productions around the Washington region.

Tickets are available at $25, $45, and $65 for musicals, dramas, comedies, and family productions, with additional free events included in the celebration.

It is an easy way to explore DC's theater scene without paying full ticket prices.

National Air and Space Museum

New exhibit opens October 30

The National Air and Space Museum opens its new At Home in Space exhibit on October 30.

The interactive exhibition explores how humans live and work in low Earth orbit and draws on lessons from the Space Shuttle and International Space Station programs. Admission is free, although timed museum passes are required.

Hirshhorn Sculpture Garden Reopens

October 31

Art lovers have another reason to head to the National Mall at the end of the month when the Hirshhorn Sculpture Garden reopens.

The redesigned garden will feature around 60 sculptures, expanded exhibition areas, improved access from the National Mall, and a new underground connection to the museum.

Do Not Forget the Fall Foliage

October is also one of the best times to simply enjoy Northern Virginia outdoors.

Popular destinations include Great Falls Park, Burke Lake Park, the Mount Vernon Trail, Meadowlark Botanical Gardens, and scenic roads around Clifton and western Fairfax County.

For a quieter weekend, a fall hike or drive can be just as enjoyable as a large festival.
