The Verdon Gorge in south-eastern France (Alpes-de-Haute-Provence), is a river canyon which is often considered to be one of Europe's most beautiful areas. The gorge itself is about 25 kilometers long and up to 700 meters deep. It was formed by the Verdon River, which is named after its startling turquoise-green colour, one of the canyon's most distinguishing characteristics. Gorgeous.
