France's Dordogne

S5 E2: The Dordogne River Valley—with its dramatic castles, evocative cave paintings, and prized cuisine—is an unforgettable blend of man-made and natural beauty. We'll take an idyllic canoe ride, and then visit a goose farm and savor the foie gras. We'll also wander through a lamp-lit castle, enjoy a country market, and visit the Sistine Chapel of the prehistoric world. Then we head south to Albi, home of Toulouse Lautrec, and the imposing fortress city of Carcassonne.
