Rondje Château de Sigy en La Seine

The ride

Roll out of Mouy-sur-Seine and the castles come first: Château de Fleurigny, then the Yonne, then Château de Misy. The Seine follows, and after Château de Sigy the Voulzie leads you to the Réserve naturelle de la Bassée. At 84.8 km with 510 m of climbing, it's a steady loop that ends where it began.
