This Halloween season, the popular Pennsylvania haunt Shocktoberfest will transform into Zombie World, a Jurassic Park-like theme park where visitors can observe zombies in a seemingly safe environment (but we know better, don't we?). Seven themed areas provide the thrills, and those adult guests looking for a more intense experience can take the Naked and Afraid Challenge, where they must sign a waiver and pass through Unknown 2.0 in nothing but their underwear. 2015 also brings an all-new escape room experience to Shocktoberfest.

Visitors brave enough take on the haunts at Dead Acres Haunted Hoochie, located outside of Columbus, will be touched, grabbed and shoved during the self-proclaimed "darkest show on Earth." While there isn't an official age restriction, the gruesome nature of the scenes paired with an obsession for chainsaws means this one is certainly not fit for children.

Pennhurst opened in 1908 as a state school for the mentally and physically disabled and operated until it was shut down in 1986. Today, Pennhurst Asylum sets the scene for an epic haunted house inside the old administration building, using digital light and sound, high-tech animatronics and excellent actors to heighten the already creepy atmosphere. Many of the props are real – leftover equipment from the state school – as are the rooms (the morgue and shock treatment rooms), blurring the lines between fiction and reality.

Hosted on Arasapha Farm just outside of Philadelphia, the Bates Motel and Haunted Hayride features three spine-tingling experiences. Visitors start on a 25-minute haunted hayride with some 75 actors and 25 different scenes before proceeding into the Bates Motel and finish in a terrifying corn maze. Pyrotechnics, digital sound and lighting, extensive animatronics and a team of highly skilled actors make this one of the most intense haunted attractions out there.

Horror comes to Salt Lake City in the form of Castle of Chaos, a completely underground haunted attraction that lets visitors pick their level of "horror." Monster-Be-Gone and General Admission are for those who prefer a no-touch haunted house experience. Participants at the Hands-On Horror and X-Scream Hands On Horror levels must sign a waiver; the former allows the monsters to touch and grab participants and the latter to move them or even separate them from their group.
