GR trails in Europe
You will come across white-red and yellow-red markers in other European countries as well, as the total GR network comprises over 100,000 km worth of hiking trails. In France and Wallonia, the letters GR stand for Grande Randonnée, in Spain for Gran Recorrido and in Portugal for Grande Rota. The same markers are also used in the Netherlands, although the trails are called LAWs there, the Dutch abbreviation for Long-Distance Walking Paths. The Flemish GR network also links up with the network of Fernwanderwege in Germany and the Long-Distance Footpaths in Great Britain.
This gigantic European network provides hikers with the opportunity to explore almost all of Europe on foot. It is possible to follow an uninterrupted GR path from east to west, from the Baltic States and Poland to Ireland, from the North Sea to the Mediterranean, from the North Cape to Gibraltar.
