Updated October 3rd, 2026 by Aaron McFarland

Halloween in Boise runs the whole month of October 2026, with haunted houses in Caldwell and Nampa open most nights, free trunk-or-treats nearly every weekend from October 10th on, and Halloween itself landing on a Saturday this year. Most of the family events are free, and the haunted attractions run about $20 to $30 a person. The standouts are The Haunted World in Caldwell for scares, Boo at the Zoo on October 24th and 25th for kids, and Harrison Boulevard on Halloween night for the decorations.
