The Massif Central is a highland region of mountains and plateaus in south-central France, covering roughly 15 per cent of the country’s mainland.
Shaped by volcanism that subsided within the last 10,000 years, the massif forms a rugged upland barrier separated from the Alps to the east by the Rhône valley—a deep north–south cleft known in French as the sillon rhodanien, or Rhône furrow. For centuries the region hindered overland travel across France, its difficult terrain isolating communities and slowing trade routes. That changed with the opening of the A75 motorway, which eased north–south passage and brought the interior of the massif within reach. Today the plateau remains one of France’s wilder corners: a mosaic of extinct volcanoes, forested slopes and high pasture that offers both ecological refuge and a window onto the country’s geological past.
