GR 9, long-distance walking route in France, connecting Saint-Amour and Port Grimaud
The GR 9 is a long-distance trail in France that starts in the Jura region near Saint-Amour and ends near the Mediterranean coast at Port Grimaud. The route is marked with the standard red and white blazes of the Grande Randonnée network and crosses varied terrain including forests, plateaus, and mountain massifs such as the Vercors and Chartreuse.
The Grande Randonnée network, of which the GR 9 is part, was developed after World War II to open up old footpaths for recreational walking. Many sections of the GR 9 follow paths that traders and shepherds had used since the Middle Ages to move between the Jura and the south of France.
Along the GR 9, walkers pass through villages where stone fountains, roadside chapels, and weekly markets give a sense of daily life in rural France. In the Vercors and Chartreuse areas, the path crosses landscapes that local communities have shaped through farming and shepherding for centuries.
The GR 9 can be walked in stages over several days or weeks, with accommodation available in villages along the way. For the mountain sections, sturdy footwear and a paper map or GPS are a good idea, as some stretches are remote and signage can be harder to follow in poor weather.
The GR 9 crosses the Vercors plateau, which served as a base for the French Resistance during World War II, and some sections of the trail pass near memorials and former hideouts from that period. Walkers who know this history will notice that certain ridgeline paths were chosen precisely because they were hard to spot from the valleys below.
