Today, on the traditional end of the French summer season, we"re featuring the wild beauty of the Gorges du Tarn, a canyon formed by the Tarn River in south central France. The Tarn Gorge is about 33 miles long and, at points, almost 2,000 feet deep. It"s a popular spot for tourists, especially kayakers and rock climbers. History buffs also find much to explore, including the castles and villages built along—or even carved into—the canyon walls, like Castelbouc in today"s image.
