Starting from Sully-sur-Loire, the Loire Valley is listed as a UNESCO World Heritage Site. The route, mostly on dedicated lanes, follows the meandering river. It passes close to Saint-Benoît-sur-Loire, home to Fleury Abbey, known as the “Romanesque basilica”. A short detour is necessary to discover the remarkable mosaic dome of the Carolingian oratory in Germigny-des-Prés. The route then joins the Chastaing promenade in Châteauneuf-sur-Loire.
