Lights Out Haunted Attraction in Denver, CO


Located in Westminster, The Frightmare Compound is Denver’s oldest haunted attraction. Founded in 1983 by Brad Holder, it is noted to be the first haunted house to spook the Denver area. Every Halloween season at The Frightmare Compound, visitors’ senses will be turned against them and their deepest and darkest fears will be intensified during the “Lights Out” haunted house nights. Our haunted attraction is known throughout the Denver metro area to provide visitors with a Hollywood-quality, truly scary experience.

Denver’s Leading Scary and Dark Haunted House

Brad Holder obsessively concocted Denver’s scariest haunted house for 16 years before falling fatally ill and to his death. He is said to be buried somewhere deep within the chambers of our compound. Since his death, The Frightmare Compound has invested millions of dollars in retaining its reputation and keeping the standards high for his Halloween haunted house.
