GR 11 (France)

GR 11 is a long-distance footpath in the Île-de-France region of France. It is part of an extensive national network of rural hiking trails. It follows a circular route around Paris, going through the départements of Val d'Oise, Seine-et-Marne, Essonne and Yvelines. Towns passed through include Chantilly, Senlis, Fontainebleau, Provins, Mantes-la-Jolie and Chevreuse. The circle is much wider than that followed by the GR 1, which also rings Paris.
