The Haunted World

Welcome to The Haunted World Idaho’s Largest Halloween and Haunted Attraction!

Since the year 2000, we’ve perfected the art of fear. As the largest indoor and outdoor haunted attraction and haunted house in the state, we offer more frightening entertainment than anyone else. We offer a spooky experience that is guaranteed to scare the pants off you, your friends, or your family. Expect around 1½ hours on weekdays, and around 2 hours on weekends, to experience The Haunted World.

There is no need to travel to Knotts Scary Farm, Universal Studios, or Salt Lake City, when the Largest Haunted Attraction in the western United States is RIGHT HERE in the Treasure Valley. Make no bones about it, our SHOW (haunt) rivals them all. It is not uncommon to have sweaty palms, discomforts in the bowel regions of your body, an irregular heart beat, and an uncontrollable urge to run… fast. WELCOME TO YOUR NIGHTMARE.

Come and join us again for TWO HOURS of unrivaled scares that will eclipse your worst nightmare…
