An electric light trail (Swedish: Elljusspår) (Norwegian: Lysløype) is an electrically illuminated trail, often completely or partly in a forest. During seasons with bare ground the electric light trail are used for among other jogging and walking. They often take the form of landscaped trails with gravel or woodchips as a surface layer. In wintertime skiing trails are groomed on many of them, if the snow conditions allow it. During this time, when the snow is groomed, jogging and walking is strongly discouraged. A common length of an electric light trail in Sweden is about 2.5 kilometres (1.6 mi).
