How to pick a Halloween event in 2026
Separate-ticket haunts like Halloween Horror Nights and Knott’s Scary Farm put all their money into haunted houses and sell out on October Saturdays, so go on a weeknight or early in the run if you can. Events included with admission, like Fright Fest and Halloween Haunt at most parks, add scare zones and mazes to a regular park day.
Families with younger kids should look at the daytime or family events (Harvest Festival, Happy Halloween Weekends, Brick-or-Treat, the Disney parties), which trade scares for trick-or-treat trails and decor. Most after-dark scare events recommend against bringing children under 13.
