The Hollenberg Pony Express Station is not officially documented as haunted, but visitors and staff have reported paranormal activity, including disembodied voices and the phantom sounds of pounding hooves. These phenomena are sometimes attributed to the spirits of Pony Express riders and the original owner, Mr. Hollenberg, who are said to linger at the historic site. The claims suggest a spiritual connection between the living and the past, though the cause of these experiences is open to interpretation. Some visitors claim to have heard disembodied voices at the station. Sounds of pounding hooves have been heard, which some believe are echoes of the Pony Express riders' phantom mounts. There are claims that the spirit of the original owner, Mr. Gerat Hollenberg, still haunts the property. The station was a vital link for the Pony Express, and some believe the spirits of the riders, teamsters, and other travelers are still present.
