The Dordogne (Occitan: Dordonha, French: La Dordogne) is a river in south-central and southwest France. The Dordogne and its watershed was designated Biosphere Reserve by the UNESCO on July 2012.
Contrary to appearances, the name of the Dordogne is not a recent word resulting from the names of the Dore and the Dogne. It comes from an ancient Durānius, derived from a Pre-Celtic root dur-, dor- (as the Durance).
The medieval forms adopted a redoubled suffix -ononia: Dorononia fluvius (sixth century), Dornonia (eighth century) that evolves in Dordonia (ninth century) by a phenomenon of dissimilation, giving the impression of an etymology *Dore-Dogne.
The river rises on the flanks of Puy de Sancy at 1,885 metres (6,184 ft) above sea level in the mountains of Auvergne, from the confluence of two small torrents above the town of Mont-Dore: the Dore and the Dogne. It flows generally west about 500 kilometres (310 mi) through the Limousin and Périgord regions before flowing into the Gironde, its common estuary with the Garonne, at the Bec d'Ambès ("Ambès beak"), in the north of the city of Bordeaux.
The Dordogne is one of the few rivers in the world that exhibit the phenomenon known as a tidal bore.
The upper valley of the Dordogne is a series of deep gorges. The cliffs, steep banks, fast flowing water and high bridges attract both walkers and drivers. In several places the river is dammed to form long, deep lakes. Camp sites and holiday homes have proliferated wherever the valley floor is wide enough to accommodate them
Below Argentat and around Beaulieu-sur-Dordogne, the valley widens to accommodate fertile farmland, well-watered pasture and orchards. In the towns, which are major tourist attractions because of their history and architecture, the quaysides are lined with eating and drinking places. In Périgord, the valley widens further to encompass one of France's main gastronomic regions, with vineyards, poultry farms and truffle-rich woodlands.
The main season for tourism in the Valley of the Dordogne is from June to September, with July and August being high season. The lifestyle and culture of the Dordogne valley attract both visitors and incomers from all over France, but also from many other countries, particularly Britain and Germany.
