The Hotel Colorado is described as haunted by several entities, including a young girl in Victorian dress seen playing with a ball, a woman believed to be a chambermaid who died tragically on the fourth floor, and the cigar-smoking presence of Walter, the hotel's founder. Common paranormal phenomena reported by guests and staff include moving elevators, flickering lights, unexplained cold spots, and the sounds of knocks and voices, particularly on the third and fourth floors. A spectral young girl in Victorian-era clothing is often seen playing with a ball, particularly on the fourth floor, where she is believed to have fallen and died. Guests report hearing a ball bouncing outside their doors. The spirit of a chambermaid, who allegedly died in a love triangle on the fourth floor, is said to cause disturbances, including screams. The ghost of the hotel's founder, Walter, is associated with the scent of cigar smoke. An apparition of an old woman has been seen peering into the basement windows, with one report of her watching a houseman named Dave. A spirit believed to be a former construction worker is said to be seen in the attic. The elevator is reported to move between floors without any passengers. Distinctive odors, such as cigar smoke and flowery perfume, are often reported. Unexplained knocks on doors and disembodied voices, including the sounds of two women talking, are frequently heard. Guests have reported experiencing unexplained pockets of cold air and lights turning on and off. Besides the specific ghosts, a woman's apparition is seen standing over beds, and some guests report feeling a presence. Fourth Floor: This is a hotbed of activity, with reports of the girl in Victorian dress, the chambermaid's screams, and a man walking the halls before disappearing. Room 454, where the chambermaid is believed to have died, is now a storage room. Third Floor: Another area with high reported activity, featuring unexplained knocks, apparitions, strange smells, and flickering lights. Basement: Site of the most frequent activity, due to its use for naval medical operations and as a morgue after being leased to the Navy.
