The landscape of the Médoc, a patch of land between the Atlantic coast forests and the Gironde, is monotonous: gravel plains, the brown water of the estuary, and gravelly soil. The D2 wine road, heading off the N15 from Bordeaux, passes through Margaux, St-Julien, Pauillac and St-Estèphe, where many of the famous châteaux reside.
