The vines

Turn left and then first right onto the Route des Sarrasins.
You will come to a wine-growing landscape. Continue straight on until you come to the crossroads with Rue des Acacias, on your left is the former wine estate of Ladignac, hence the name of the place.
Turn right into rue des Acacias, and before the crossroads on your left, you will see the magnificent Château Ricaudet Troussas.
