A rollicking journey through Boulder and its storied history, Banjo Billy’s Bus Tours uses one of the funkiest vehicles you’ve ever seen. Featuring armchairs for guests inside, the exterior looks like the offspring of a log cabin and a school bus—and features 13 disco balls, five saddles, and a rubber chicken! The 90-minute tours delve into ghost stories and lurid tales of crime, but the tone is tongue-in-cheek and entertaining. Banjo Billy also offers Denver tours.
