Previous visitors to our haunted house have become loyal customers and return each and every year. If you are looking to have an authentic and surreal experience with your friends or family this Halloween, make certain to visit one of the scariest haunted houses in Colorado.

THREE NEW ATTRACTION THEMES for 2017!

Darkest Dreams: Transcend into a dream world of terror that would scare even the bravest of souls. A demonic entity pulls you into her nightmare where she gathers all creatures of horror. You can run, but you can’t hide from Nachtmah’s deadly grip. Attempt to escape her reality, or fall prey to the demented creatures she plans to unleash on all who enter her world. You are getting sleepy…

Slaughter: Residents are slowly vanishing in the quiet, eerie town of Coalfell. Rumor has it that every 20 years an unusually high rate of murders with an increased number of disappearances strike the city, but no one will speak to the issue for fear they will be next. Strange reports describe terrorizing shape shifting creatures, most often seen as evil clowns. Trespassers beware, for these petrifying entities prefer new visitors. Stay focused on your visit to Coalfell, if you don’t you might just become their next permanent resident...

Undead: Restless Spirits: A decaying mansion sits alongside a decrepit cemetery and mausoleums just outside of Denver. This seemingly abandoned manor is a permanent home to evil permanent residents who were unwittingly awakened by a local psychic, Madame Shelta. Now, unwelcomed trespassers will relive the horror of the lady of the house who took her own children’s lives after the house terrorized her and convinced her to kill them. That unfortunately, is not the end of the story. The grief-stricken husband, in a fit of rage, murdered his wife for her evil deeds before taking his own life. The house staff discovered the horrifying murder scene and made a blood vow to keep the family safe in this life-and the next. They staff will harm anyone who dares to disturb the tragic…and gruesome final resting place.
