Invoked by the late-medieval poets, the powerful and serpentine course of the emerald Tarn cuts its way across the plateau landscape. The sheer stone faces it has hewn are one of the region's great attractions and visitors come from far and wide to admire its winding path of cliffs and cascades. Villages nestle in the rocky landscape dotted by colourful pockets of vineyards and orchards. Ruined castles punctuate its course. Exploring by car or kayak, you may be sure of a spectacular experience.
