Departure from Cernay-la-Ville (Yvelines)
A loop starting from Cernay-la-Ville. Head west towards Le Perray and Vieille-Église. Return via the Rambouillet Forest. 75% of the route is in the forest. Start and finish in the town centre.The circuit is almost flat (a small descent and climb towards the end), with a little road at the start and end (2 x 1.5 km) and the rest on forest paths. No technical difficulty, but it's not a leisurely ride (not suitable for families), as the paths can be very bumpy (stones, ruts, etc.) but are nevertheless often very beautiful.
