Castles between Le Rhône and La Bourbre

The ride

Roll out of Hières-sur-Amby and the route unfolds past the Château du Cingle, then follows La Bourbre before climbing gently to the Fort de Genas. From there it's on to the Canal de Jonage and along Le Rhône, with 329 m of elevation spread across the way. The 69.4 km loop is entirely paved, so it rolls back to where it began.
