 This height approximately corresponds to that of the highest settlements in Europe and to the tree line in several mountain ranges such as the Alps and the Pyrenees, where most of the highest roads are located.Some of the listed roads are closed to motorised vehicles, although they are normally all accessible to pedestrians and cyclists.These mountain roads are visited by drivers, motorcyclists, hikers, and bicyclists for their scenery and often feature in the routes of European bicycle races such as the Vuelta a España, the Tour de Suisse, the Tour de France and the Giro d'Italia.
