Roll out of Genneton and let the castles come to you: first the Château d'Argenton, then the Château de Sanzay, with the Le Dolo and L'Ouère rivers slipping by between them. Further on, the Château de Somloire and the Manoir de la Roche-Coutant keep the theme going before the route settles into the Parc naturel régional Loire-Anjou-Touraine. The 84.4 km loop is fully paved, so you can keep your eyes on the scenery rather than the ground. Back to Genneton with a few castles and rivers behind you.
