House of Torment Chicago, Morton Grove

Though the haunted alleys, crumbling subway tunnels, and blood-stained storefronts of Fear City are creepy enough, they aren't the reason why visitors tend to leave screaming. This ghastly municipality has more than 100 citizens—including deranged nurses and blood-covered asylum inmates.

These are just some of the scares that await within Fear City's 40,000-square-foot sprawl. The indoor attraction consistently places on hauntedhousechicago.com's top 13 rankings, and the city's always looking for new recruits: visitors are encouraged to dress up, join the madness, and take home whichever crazed clown they think would make a good roommate.
