France's Bordeaux and the Dordogne

The world’s finest wines, sweeping vineyards and fine food couple with a river valley dotted with castles. We sample the best Bordeaux then cruise the lovely Dordogne and Lot rivers with stops at chateaux, ancient watermills, and perched villages. Cooking classes and an underground adventure to see pre-historic cave paintings round out the trip. Tips on wine tasting and walking paths.
