The Colorado Grande Casino is considered a famously haunted location in Cripple Creek, primarily due to its history as a furniture and coffin shop that also housed a mortuary and morgue. Notable hauntings include sightings of a red-haired woman named "Maggie" on the upper floors and a young female spirit called "Lily" who is said to enjoy purple balloons. The building's original use as a furniture and coffin shop, with its own mortuary and city morgue, contributes to its paranormal reputation. The most prominent reported apparition is Maggie, a red-haired woman often seen on the casino's second and third floors. Another reported spirit is Lily, a young female ghost who employees say has a fondness for purple balloons. The casino is considered one of the most haunted spots in the United States and has a history tied to the town's rise and fall, including its mining boom and bust periods.
