The Frightmare Compound in Denver, CO: Halloween Haunted House Attraction

Do you have the courage to make your way to the end of our haunted attraction like other Denverites?

What Lurks in the Shadows

What makes our haunted house different from others in the Denver area is the history. In 1983, a man by the name of Brad Holder founded The Frightmare Compound. He started a horror house to serve Denver and the nearby communities, somewhat similar to what we know and love today. He was obsessed with his work, and in his will, stated he wanted to be buried somewhere on the property grounds. It is said that years later, he can still be found roaming the compound, looking for souls to bring with him into the afterlife.
