A continental web of trails spanning over 60,000 kilometres
In short: Across Europe, a sophisticated network of long-distance walking trails connects diverse landscapes, from the Pyrenees to the coast of Portugal. Known as GR footpaths, these routes rely on a standardized visual language of red and white blazes to guide hikers through forests, mountains, and cities.
The GR (Grande Randonnée) network is a massive infrastructure of long-distance trails primarily located in France, Belgium, the Netherlands, and Spain. In France alone, these routes cover approximately 60,000 kilometres. While the name varies by language—such as 'Langeafstandwandelpad' in the Netherlands or 'sendero de gran recorrido' in Spain—the core concept remains a 'great route' designed for significant trekking distances. The Portuguese network includes the Percursos Pedestres de Grande Rota. These paths range from short circular loops to long linear treks. For example, the GR 22 covers 540 kilometres in a circular format.
Navigation across these vast distances is made possible by a specific system of blazes. In most of the primary countries, these marks consist of a white stripe above a red stripe. This specific color combination was selected because it provides the highest visibility against natural surroundings. While these markings are often painted directly onto trees or rocks, they may transition into metal signs when the trail enters urban centers. In Switzerland, the system differs slightly, utilizing either red and white bars or yellow diamonds. The markings are designed to be legible in both directions. This ensures that hikers can navigate the path regardless of their heading. The system is used consistently at forks and crossroads.
The maintenance and governance of these trails are handled by national bodies, such as the French Hiking Federation and the Spanish Mountain Sports Federation. These organizations manage complex international routes that cross multiple borders, such as the GR 7, which traverses Spain, France, and Andorra. The network also includes specialized circuits like the GRP in Andorra and the HRP in the Pyrenees, which combine elements of various regional routes to create expansive, multi-country hiking experiences. The French Hiking Federation has even introduced a public voting system since 2017. This allows people to choose a favorite trail for an annual award. The network also features specific routes like the GR 13-E4, which spans 240 kilometres.
