Monster Mash on Main St. brings a free family Halloween celebration to The District at Green Valley Ranch on October 31st, 2026. From 4:00 PM to 7:00 PM, Main Street will be filled with trick-or-treating, live music, Halloween characters, local vendors and a children’s costume contest.
The outdoor event gives Henderson families a place to celebrate Halloween before heading out for the rest of the evening. Children can dress in costume, collect candy from participating businesses and meet characters including Dracula and Frankenstein while families explore the shops and restaurants throughout The District.
Trick-or-Treat Along Main Street
Participating businesses along Main Street will hand out treats during the event while supplies last. Families can walk through The District at their own pace, stopping at participating storefronts and enjoying the Halloween atmosphere along the way.
Because candy and individual activities may be limited, arriving earlier in the event can give families more time to make their way through the participating locations.
Meet Halloween Characters
Costumed Halloween characters will be stationed throughout the event, including recognizable favorites such as Dracula and Frankenstein. The characters add another interactive element for children and create opportunities for Halloween photos throughout Main Street.
The event is designed to be festive and family-oriented rather than a haunted attraction, making it suitable for children who enjoy Halloween without intense scares.
