These are the haunted house reviews available for Halloween haunted attractions in Oregon. One of our Scream Teams has written each review based on our standard criteria, which apply to all haunted attractions. These criteria range from Cast and Costuming to Special Effects, Customer Service, and, of course, the Scare Factor! Click on a haunt’s name to go to their most recent review, or if we have older reviews available, you can find them in the “Archives” section to see how they’ve changed over the years.
