The Frightmare Compound has become a staple in the Denver and Westminster area of Colorado as a premier haunted house attraction to visit during the Halloween season! Over the past 3 decades, we have welcomed thousands of hungry patrons who crave “The Feeling”. The feeling of PANIC…of WEAKNESS…of complete and utter FEAR, and year after year we deliver to our guests who are thirsty for more. We offer three terrifying horror house experiences! We pride ourselves in being Colorado’s #1 rated haunted attraction and bringing our guests a Hollywood quality haunted house experience in Westminster, CO. Considered as the most horrifying haunted house in the Denver area, this is not for the weak hearted.
