The intuitive path that is created by walkers/hikers or drivers vs a marked trail or road. Once established it can become an alternative or preferred route. Typically it is a short cut on a marked trail or road but it can also be a well-worn ribbon of exposed soil or rut in an open space where there are few trails to connect desired areas.
