A *desire path* (also known as a *desire line*, *social trail*, *goat track*or
*bootleg trail*) is a path developed by erosion caused by footfall or by
bicycle. The path usually represents the shortest or most easily navigated
route between an origin and destination. The width and amount of erosion of
the line represents the amount of demand.
Desire paths emerge as shortcuts where constructed ways take a circuitous
route, have gaps or are lacking entirely. The paths take on an organically
grown appearance by being unbiased toward existing constructed routes.
Desire paths manifest on the surface of the earth where original movement
by individuals indicates, thereby encouraging more travel. Explorers tread
through foliage or grass, leaving a trail "of least resistance" for
followers.
