Western Pyrenees

The western Pyrenees rise above Béarn in steep ridges and deep valleys. The valleys of Aspe, Ossau and Barétous cut through the mountains towards passes leading south. Their high pastures have long supported flocks brought up from lower ground in summer, while woods cover many of the slopes below. Snow, rocky summits and narrow crossings make these mountains a formidable barrier between the lands on either side.
