#6 Philadelphia, Pennsylvania
Like any major city, Philadelphia offers parties and shows that cater to Halloween fanatics, but what Philadelphia has that other cities don’t, is the Eastern State Penitentiary. Now, the Penitentiary is spooky and scary on average days as is, but it transforms into a massive haunting attraction known as Terror Behind the Walls for the month of October. It is a premier haunted attraction that crushes most other haunted houses and trails – it has 6 different interactive scenarios where people have the option to make the experience physical. Just make sure you get your tickets in advance.
