The Cantal Volcano and the Saint-Flour Region
The Cantal Massif is a wonderful playground for lovers of wide open natural spaces, spanning a diameter of around 70 kilometres.
It is one of the most significant volcanic regions in Europe, notably featuring the Plomb du Cantal and the Puy Mary.
Peaks, mountains and plateaus have gradually taken the place of the enormous volcano that once stood there.
Hikers walk at altitudes ranging from 750 to 1,855 metres, taking in breathtaking scenery.
From Plomb du Cantal or Puy Mary, you’ll get a real sense of this almost mountainous region, which has become a vast high-altitude pasture.
To the east of this route lies Saint-Flour, a ‘Land of Art and History’ and a Cluniac site, nestled at the foot of the Margueride mountains.
Perched on its basalt promontory, Saint-Flour, through its bishop’s palace and cathedral, jealously guards the memory of its former prosperity. It is the gateway to the flattened peaks of the Margeride, dotted with granite boulders, to the Truyère Gorges and to the vast basalt plateau of the Planèze.
