Once in the village of Saint Avaugourd des Landes, go to the center. At the crossroads, take Rue du Stade in the direction of Avrillé and in the descent, number 17 will be on the left, near the speed bump. If you come from Avrillé, 17 will be on your right. The gate is blue, equipped with a videophone.
Be careful, the rue du Stade extends into the route d'Avrillé which also includes a number 17!
