The big road routes of the actuality are, in a lot of cases, fruit of the experience of centuries of history: from the first hominids hunters and trashumantes until the most remote settlements, the history of the mankind has done walking, and could even say that the ways like such are born with the first populated.
Of the Half Age date some of the historical ways more important, like the Way of Santiago, first Cultural Itinerary European, arose like this a series of main roads that joined the diverse populations. Little by little, with the increase of the roads of communication, some of the ancient ways were falling into disuse, although in the areas of mountain kept on being indispensable the small footpaths that the inhabitants of the territory used to displace .
With the industrialisation, the implantation of a road network, the increase of the population and the construction, many of these ways finished for disappearing.
Along the last years have gone recovering these roads, especially the main, and have arisen like this the GR, or itineraries of more than 50 km of length.
The GR are a network of recognised and apt ways for the pedestrian tourism that find by all Europe and that are coordinated by the ERA – European Ramblers Association (with versions in English, French and German).
In Catalonia, country with an important tradition excursionista, constituted thirty years ago the Catalan Committee of Footpaths, inside the organisation chart of the Federation of Entities Excursionistas of Catalonia. In a principle, the paramount aim of this entity was to mark his itineraries, so that the excursionistas did not lose . Nevertheless, over time it has gone realising an importantísima work of recovery, cleaning and signaling of ways. Of this form, has gone creating all a Catalan network of footpaths, with crowd of variants.
The specific marks of GR are two bands, a white and another red. Besides, there are four types of signals: direction to be followed, derivación, mistaken direction and change of direction.
