Roll out of Arromanches-les-Bains and let the castles come to you: first the Château du Petit Fontaine, then the Château de Fresné and the Manoir du Pavillon. The route keeps unfolding past the L'Aure and La Drôme rivers before the Château de Commes sends you homeward. With 56.9 km underfoot and a 486 m climb, you'll roll over a mix of paved and unpaved lanes. Castles, two rivers and a loop back to the coast — that's the shape of this one.
