Denver's World Famous Haunted House

40 Years Of Terror!


Do You Dare to Enter Alone?

This legendary horror house was started over 35 years ago by Brad Holder and has been innovating its scares ever since for the Boulder community. It is said that Brad Holders' last known resting place was right here on the grounds of our most terrifying haunted attraction. Legend has it that once Mr. Holder left this world, his soul still roams on the land as it was the last place he knew. Our Boulder customers have reported sightings of him, but nothing was ever proven. Do you dare face the ghost of Mr. Holder and the consequences that await?
