You may park your vehicle in the Ferme de Turnac car park provided you go to the shop to ask permission to park and walk along the edge of the walnut groves beside the River Dordogne. These very courteous people will not refuse you.
(S/E) From the farm’s car park, head straight down the path to the Dordogne.
(1) Turn left and walk along the river. Enjoy the view of the castle and the hamlet of Montfort.
(2) Turn left and walk along the walnut grove until you reach the path. Turn left to return to the car park (S/E).
