From Carpentras get the direction "Bédoin Mont Ventoux". About 1 Km after the round about "St Pierre de Vassol" (supermareket superU on the left) turn on the left to "Crillon le Brave". Climb up straight to Crillon till a small round about. Then go down in the direction "Bédoin Mont Ventoux" . At the bottom of the descent, at the exit of the big right turn, take on your left hand the "chemin de la madeleine". Pass the speed bump , then le Brin de Bois is a bit further at N° 176 B on your right hand (large wood sign near the mail box)
