Chambers of Fear Haunted House, Glendale

When the macabre minds behind Chambers of Fear opened their first haunt more than 20 years ago, their bone-chilling scares filled only a three-car garage. Over the years, though, the attractions have grown to encompass everything from haunted corn mazes and scream cams to infinitely long algebra tests. These days, the experience stretches more than 25,000 square feet, with high-tech animatronics, creative scares, and traditional maniacs scattered among three haunted houses: Scary Tales, Darkness: Industrial Nightmare, and Chambers of Fear. Including "some of the best scares in the industry," according to Ed Edmunds of Travel Channel's Making Monsters, the sprawling spookfest startles with bloodied ghouls and manifest phobias alike.
