The Grand Canyon of France -- The ebbs and flows of the Ardèche, France's fastest-flowing river, have created the Grand Canyon of France. Littered with alluvial deposits, strewn in ravines whose depth can exceed 285m (935 ft.), the river's final 58km (36 miles), before the waters dump into the Rhône, is one of the country's most unusual geological areas. A panoramic road (D290) runs along a rim of these canyons, providing views over an arid landscape of grasses, trees, hardy shrubs, and some of the most distinctive deposits of granite, limestone, and basalt in Europe.
The beautiful driving route, which you can traverse in a few hours even if you stop for sightseeing (follow signs directing you along well-marked footpaths), stretches north to south between the towns of Vallon-Pont-d'Arc and Pont St-Esprit. The meandering corniche roads are a challenge. Look out for other vehicles weaving frighteningly as drivers and passengers admire the scenery and snap photos.
