Terror Behind The Walls, Philadelphia
(2.9/5 based on 75+ reviews on the web)
Terror Behind the Walls, America’s largest haunted house, is located inside the massive castle-like walls of Eastern State Penitentiary in Philadelphia, PA. Now in its 24th year, this extraordinary theatrical production is consistently ranked among the top haunted attractions in the country. In 2014, Terror Behind the Walls runs on select evenings from September 19 through November 8. The event is the largest of its scale to offer visitors the option of an immersive experience.



Terror Behind the Walls begins with a critical decision: should you explore the prison and watch the action, or should you mark yourself to truly interact with the denizens of the cellblocks? Those who opt in for true interactivity may be grabbed, held back, sent into hidden passageways, removed from their group, and even occasionally incorporated into the show. They will deal with the consequences of their decision through six long attractions.

  • Although pricey, this is one of the finest haunted attractions around. Be sure to take your time going through the exhibits. Even going slow, it will take no more than 30-45 minutes to see everything....  more »
  • Very well laid out - but handling lines could be a bit better in the way of keeping waiting clients entertained (more "monsters" outside would have been great) The setting is creepy, really makes you ...  more »
