Pass through Pommeuse via the D216. Just before the bridge over the Grand Morin River, turn left onto the greenway. For 2 kilometers, bike through meadows and along the shady banks of the Aubetin and Grand Morin, before turning left back onto the road. At the first crossroads, turn right towards Courtalin and further on rejoin the Grand Morin along a lovely country lane. At the stop sign opposite the overhanging chapel, turn right to enter La Celle-en-Bas. Cross the village and then gradually climb the D20 secondary road between the river and wood. At the yield sign, make two successive right turns. Bike down towards the houses along Rue de la Croix Jacquée, before turning left to the school. At the second stop sign, opposite the park, turn right. Pedal down the road, cross over the Grand Morin and immediately after the bridge make a sharp left turn towards the Moulin de Bicheret watermill. Careful, visibility is poor here.
