Trails are blazed with characteristic marks consisting of a white stripe above a red stripe. These appear regularly along the route, especially at places such as forks or crossroads. The network is maintained in France by the Fédération Française de la Randonnée Pédestre (French Hiking Federation), and in Spain by the Federación Española de Deportes de Montaña y Escalada (Spanish Mountain Sports Federation). Many GR routes make up part of the longer European walking routes which cross several countries.
