Les Bois
The road leaves Dreux and heads broadly southwest through rolling countryside of southern Normandy. It passes the town of Saint-Lubin-des-Joncherets, now in the upper valley of the river Avre. It next comes to Verneuil-sur-Avre, where the RN26 heads northeast to Caen. The countryside is more wooded now as the road crosses the "Les Bois Francs" before coming to the "Forêt du Perche".
