From Dauprat you roll out past Château d'Armailhac and Château Cos d'Estournel, castle after castle lining the way. Château Cos Labory and Château Pedesclaux follow before the route turns into the Parc naturel régional du Médoc. Then it's on through the Parc naturel marin de l'Estuaire de la Gironde et de la Mer des Pertuis. The 72.7 km loop is almost entirely paved and brings you back to Dauprat.
