Best Places to Celebrate Halloween in Thornton, Brighton, and Northglenn

Halloween falls on a Saturday this year, which means a whole weekend of options. Whether you're after candy, a safe place for little ones, a big night out, or a classic walk through the neighborhood, Rhino Realty Pros has you covered. Rick Cavallaro rounded up the best ways to celebrate around Adams County, sorted by what kind of Halloween you're looking for.

Best for Little Kids: Trunk-or-Treats

Peak Martial Arts Trunk or Treat, Thornton

Sat, Oct 24, 4-7 p.m. at 12421 Washington St.

A walk-through trunk-or-treat lot, a haunted bus, indoor games, photo spots, and prizes. Admission is $2, and all participants need to register in advance.

Northglenn Christian Church Trunk or Treat

Sat, Oct 31, 1-3 p.m. at 1800 E. 105th Pl., Northglenn

A good daytime option for toddlers and young kids who need an early bedtime. Costumes are encouraged and there are plenty of decorated trunks to visit.

A trunk-or-treat is also listed on East 128th Avenue in Thornton on Halloween afternoon, starting around 2 p.m. That one comes from event listing sites, so check with the host for details before heading over.

Best for an Organized, Contained Setup

Brighton Treat Street

Sat, Oct 24, 5-7 p.m. at Brighton Park, outside the Brighton Rec Center

Free trick-or-treating in a safe, festive setting with costumes, candy, and community spirit. If you're reading this on Saturday afternoon, it's happening this evening.

Hyland Hills Halloween Trick-or-Treat Spooktacular, Westminster

Fri, Oct 30, 5-7:30 p.m. at Adventure Golf & Raceway, 9650 Sheridan Blvd.

Trick-or-treat stations along three mini-golf courses, a family-friendly haunted maze, a photo booth, glitter tattoos, and a balloon artist. A $5 meal deal is available.

Best for the Classic Experience: Your Own Neighborhood

For many families, nothing beats going door to door on Halloween night. The best streets for it share a few things: sidewalks and working streetlights, homes close together so kids can cover more ground, calm traffic, and neighbors who sit out front, decorate, and hand out candy. Compact blocks and cul-de-sacs tend to work especially well for younger kids. Sunset comes before 6 p.m. at the end of October, so bring flashlights or glow sticks and put reflective gear on the little ones.

Best for Adults: A Night Out in Thornton

If you're done with the candy run and want a night out, The Castle Event Center at 83 E. 120th Ave. in Thornton is listed as hosting the Dark Harvest Masquerade Ball on Halloween night starting at 9 p.m., along with DarknessCon Denver. Those are adult-oriented events, so check the host's ticket page for age requirements and pricing before you plan on it.

A Free Neighborhood Test Drive

If you're thinking about buying, Halloween evening is one of the best times to see a neighborhood in action. In an hour you'll see how many families live there, how lit and walkable the streets are, how the traffic feels when it's busy, and whether neighbors come out and interact. That's information you can't get from a daytime showing, and it's a great way to compare the streets on your short list side by side.
