Located a short scurry down the foggy lanes from downtown Eureka Springs, AR, the 1886 Crescent Hotel and Spa is said to be one of the most haunted hotels in the world. The building once housed a “cancer curing hospital.” Unfortunately, the hospital was responsible for false hope and worse thanks to a useless cure of watermelon seed, brown corn silk, alcohol, and carbolic acid developed by known charlatan Norman Baker. Mediums suggest that the current hotel may house a portal to the “other side” where the former hospital’s morgue used to be. As long as he’s not a traveling snake oil salesman, Fido should get along well with the area’s poltergeist population. He might act the tough pup when it comes to the “Girl in the Mist” or the “Ghostly Lady in Room 3500,” but can he handle the fur-raising specter of an orange tabby in the lobby? Morris showed up at the hotel in 1973 and decided never to leave, even after he died. His headstone can be found in the East Lawn area, but it’s said that his presence can still be felt when he brushes up along guests' legs inside. Maybe that’s just Jasper, the current hotel cat.

Dogs are allowed on Crescent Hotel Ghost Tours with prior approval from the tour guide and other participants. Two pets of any size are welcome to stay overnight for an additional fee of $35 per pet, per night.
