Rondje Château d'Autichamp en La Drôme

The ride

From Montmeyran you roll out toward the Parc naturel régional du Vercors, then follow La Gervanne and La Drôme as they thread through the landscape. A castle, the Château d'Autichamp, breaks up the ride before the Réserve naturelle des Ramières du Val de Drôme brings the nature back in. It's a 73.5 km loop with 1139 m of climbing, and every metre of it is paved. Back to Montmeyran you go, with two rivers and two nature reserves behind you.
