A plurality of biodegradable stakes for use as trail markers that are coated with a biodegradable coating comprised of an adhesive and a fluorescing compound for inserting into the ground such that the coated surface of the marker is exposed at various distances from each other such that the stakes glow when a source of ultra-violet light is present and thus form a route or trail by which a person can find their way to a point of interest even in low light conditions, while remaining unobtrusive so that one has difficulty seeing the stake without ultraviolet light and unless one is specifically looking for it thereby not detracting from the natural appearance of the location.
