Coming from Toulouse or Albi, take exit no. 7, direction Rabastens. Cross Rabastens then head towards Grazac. At the entrance to the village, just before the school, take the first road on the left (Les Millets). Then always to the right.
Coming from Montauban, follow the GPS (Les Hauts de Grazac) on Google maps and you will arrive at your destination.
