The Oregon Vortex is a roadside attraction that opened to tourists in 1930, located on Sardine Creek in Gold Hill, Oregon, in the United States. It consists of a number of interesting effects, which are gravity hill optical illusions, but which the attraction's proprietors propose are the result of paranormal properties of the area.
