Hiking in France moves from the high Alps around Mont Blanc and the Écrins to the pink granite coast of Brittany and the volcanic ridges of the Massif Central. Legendary GR routes thread through the Vercors, the Pyrenees, and Corsica’s GR20, while day hikes above Annecy or around Chamonix deliver the kind of big mountain scenery that makes France easy to return to.
