¿Qué es un GR o un Gran Recorrido?
GR (Gran Recorrido in Spanish) is the name given to trails of tourist and scenic interest of at least 50 km in length which take more than a day to cover on foot.
Furthermore, the characteristics of these footpaths must allow their use by most users throughout the year. This type of trail may also have associated links, branches and alternative routes, which will be marked using the GR colour code.
GR long-distance trails are blazed using characteristic markings, consisting of a white stripe above a red strip, which are usually painted on tree trunks, rocks or specific signposts accompanied by the initials GR.
The allocation of numbering in Spain is the responsibility of the Spanish Mountain Sports and Climbing Federation (FEDME). However, each regional and/or territorial federation is responsible for administering the part of the trail that runs through its territory. The officially recognized trail forms part of a network of local, regional and/or territorial footpaths and must meet specific requirements regarding its layout and signposting.
