Opened in 1927, the Hotel Monte Vista quickly became a hub for celebrities and travelers along Route 66 — today it’s one of Arizona’s most haunted hotels. Guests frequently report a phantom bellboy knocking on doors only to vanish, and Room 220 is notorious for unsettling encounters with a long-term guest who died there; visitors still hear coughing and see the bedclothes pulled away. Other spirits include a woman who fell to her death from Room 306 and a pair of ghostly women seen lingering in the halls. With its colorful history and eerie legends, the hotel remains a favorite stop for both tourists and paranormal investigators.
