This itinerary follows the truly spectacular River Tarn as it winds back and forth along the Tarn Canyon or Gorges du Tarn. With each turn the drive becomes more beautiful, never monotonous. The road cuts through the canyon always in sight of the peaceful waters of the Tarn and its picturesque villages, clusters of warm stone buildings that nestle above its shore. Encased in deep limestone cliffs, the river canyon is at its most glorious in early autumn—a perfect time to visit.
