Colleyville Fall Events 2026: Your Seasonal Guide by Age
"Unlike previous years, this rendition of Haunted Trails will be more trick than treat." That line comes from the City of Colleyville's 2026 event page. The next sentence explains the change: the walk is being "catered to an older crowd," and the city now recommends it for pre-teens and older.
On its own, that's a small programming change. Put it next to the rest of the fall calendar and a pattern shows up. The events that used to overlap now each serve a clearer audience. Young children get a full Saturday morning at City Hall. Older kids and teens get a darker Thursday night at the Nature Center. Adults get two new things: a makers market the city is putting on with a local gallery, and a walking trail that's still being planted. If your household includes more than one of those groups, it helps to plan the season around that split.
Haunted Trails returns to the Colleyville Nature Center on Thursday, October 29. Gates open at 6:30 p.m. with food trucks, a DJ, and treats. The haunted walk runs from 7 to 8:30 p.m., and the city promises zombies, witches, and clowns along the trails.
The setting suits a spookier event. The Nature Center at 101 Mill Wood Dr. covers 46 acres, with nine ponds, 3.5 miles of multi-use trails, an amphitheater, a covered pavilion, and a fishing pier. During regular hours it's open from 30 minutes before sunrise to 30 minutes after sunset, so a walk after dark there is something you normally can't do. The city's directions point you west on Glade from Highway 26, then south on Mill Creek.
October 29 is a school night, and the new age guidance means families with younger children need a different Halloween plan. The city already has one on the calendar.
The annual Harvest Festival runs Saturday, October 17, from 10 a.m. to 2 p.m. at City Hall, 100 Main Street. It's free and includes a Trunk-or-Treat, games with prizes, a petting zoo, face painting, and fall crafts. For families who just lost Haunted Trails as an option, this is the event to plan around, and the costume contest schedule starts with the youngest age group:
Local Colleyville businesses and nonprofits run the Trunk-or-Treat from decorated cars in the parking lot behind City Hall, and a winning trunk is announced at the event. Food trucks take cash or card. Free parking is available in City Hall's south lot and at City Park.
If a toddler's contest is at 10:30 and an older sibling's is at 11:30, plan on most of the morning. The pet contest at noon gives the dog a turn too.
This year the Harvest Festival adds something built for the adults pushing strollers. The city calls it the Harvest Market. It's new for 2026 and is organized in partnership with ART ALGΣBRA. The city describes it as "a thoughtful mix of local makers, small businesses, food vendors, farmers, and more." No vendor list had been published as of early October. Vendor applications were still open when the market was announced, so the lineup is still coming together.
The partner is local. According to the Star-Telegram's July 2026 coverage, Art Algebra is a Colleyville art gallery with a coffee bar inside, at 1001 Glade Road, Suite 100, next door to girligirl boutique. The owners, Aashna Bharwani and Aatif Merchant, come from education and economics. They opened the gallery because they loved the handmade pieces they kept finding at festivals.
Merchant explained the name to the paper:
"The algebra is finding the missing piece that curates your home, that finishes what you want to decorate and makes your life complete."
So a gallery started by people who found their favorite art at festivals is now the city's partner on a festival market. For Colleyville's biggest free fall event, that's a change in who the morning is for. Kids still get the costume contests. Adults now get a market to browse while they wait.
The fall's other adult-focused addition has no date on the calendar. The Texas Tree Trail sits on nine acres behind the Colleyville Senior Center at 2512 Glade Road. It has a half-mile walking trail lined with trees native to Texas. The city's beautification staff proposed the project with the Colleyville Tree Board, City Council backed it in October 2025, and work began in early 2026.
This is the trail's first fall, and it's only partly planted. Here's where each phase stands:
| Phase | What it covers | Status as of early October 2026 |
|---|---|---|
| Phase I | 42 larger trees, including oaks, magnolias, Texas ash, Montezuma cypress, American elm, pine, and bigtooth maple | Completed early in 2026, according to Community Impact |
| Phase II | 64 flowering trees, including crape myrtles, redbuds, desert willows, Texas mountain laurels, Mexican buckeyes, and Eve's necklace | Council approved about $65,146 on April 21. The city scheduled planting for May but has not posted that it's finished |
| Phase III | The rest of the trees along the walking trail | Listed by the city as "coming soon," with no date |
Community Impact reported that later phases could add landscaping, signage, and lighting, and that the full project is expected to take three to five years from when discussions began in October 2025. So the trail you walk this October is an early version. The city also posts a tree legend and a design map for the trail. Bring the legend along and you can see which plantings are already in and where future ones will go.
The Senior Center has its own season-long calendar right next to the trail. Its Halloween Costume Party and Bingo is Friday, October 30, from 11:30 a.m. to 1:30 p.m. The Holiday Party is December 11, and the Holiday Dance is December 16.
The same age split carries through the city calendar into December.
| Date | Event | Where | Who it's built for |
|---|---|---|---|
| Tue., Oct. 6 | National Night Out | Heroes Park at City Hall | Families; free food, games, and activities |
| Sat., Oct. 17 | Harvest Festival and new Harvest Market | City Hall, 100 Main St. | Young kids, pets, and adults browsing the market |
| Thu., Oct. 29 | Haunted Trails | Colleyville Nature Center | Pre-teens and older, per the city |
| Fri., Oct. 30 | Halloween Costume Party and Bingo | Colleyville Senior Center | Senior Center participants |
| Sat., Nov. 21 | Christmas Tree Lighting Celebration, 5:30 to 8:30 p.m. | City Hall, 100 Main St. | All ages; Santa, food trucks, choirs, Jingle Bell Junction |
| Dec. 11 and Dec. 16 | Holiday Party and Holiday Dance | Colleyville Senior Center | Senior Center participants |
National Night Out comes with a bonus. It's one of the first big gatherings at Heroes Park since the expanded park's official grand opening and hero induction on June 26 during Stars and Guitars. The event starts at 5:30 p.m. The city's listings give two different end times, 8 p.m. and 8:30 p.m., so check before you go if you plan to stay late.
One more outdoor event is still waiting on a date. Texas Junior Anglers is listed for Anglers Pond at the Nature Center as "TBD." It's a free family fishing day at a freshly stocked pond, with prizes for children 16 and under.
Most of these events are a short drive from Colleyville Boulevard, where food options are still changing. Smoothie King opened August 31 at 5615 Colleyville Blvd., Suite 140. For an adults-only evening, Pop & Pour, a sparkling wine lounge that opened in late May at Colleyville Town Center, 5665 Colleyville Blvd., Suite 150, fits the grown-up side of this fall's calendar.
Several more are announced but don't have confirmed dates yet. Lucile's is coming to the former Zafiros space in The Village at 5204 Colleyville Blvd., with an opening reported for late 2026. Lean Kitchen, a meal-prep and grab-and-go shop, is slated for late 2026 at 5604 Colleyville Blvd. Tick Tock Taco's second location at 4605 Colleyville Blvd. lists late October on the company's site. The Star-Telegram reported late November in September, with construction still underway. For a taco stop after Haunted Trails, confirm Tick Tock Taco is open before you count on it.
