A trail, also known as a path or track, is an unpaved lane or a small paved road not intended for usage by motorized vehicles, usually passing through a natural area. In the United Kingdom and Ireland, a path or footpath is the preferred term for a pedestrian or hiking trail. The term is also applied in North America to accompanying routes along rivers, and sometimes to highways. In the US, the term was historically used for a route into or through wild territory used by explorers and migrants. In the United States, "trace" is a synonym for trail, as in Natchez Trace.
