Antioch’s official trick-or-treat hours are 3 to 7 p.m. Saturday, Oct. 31. Families are encouraged to prioritize safety by ensuring children use flashlights, glow sticks or reflective tape and wear light-colored costumes. Trick-or-treaters should stay on sidewalks and look both ways before crossing the street. Residents who wish to participate are asked to leave their porch lights on, while those who do not should keep them off.
