Asylum and The 13th Floor are put on by the same creator, so expect a similar experiences -- as in, they’re both scary as hell and more suited for the braver souls. This Mile High favorite for screams boasts 10,000 square feet of unadulterated terror. Once you head in, there’s a whole lot of demons, killer clowns, and blood and gore until you get out. Like Asylum, this one’s open most days during the week (and more expensive on weekends).
