The Coulommiers railway station

Leave the Coulommiers railway station on your right and continue along the bike path. Cross the level crossing and turn immediately right onto Boulevard du Docteur Lorigny. Continue straight on until the stop sign at Avenue Robert Elvert. Cross and continue opposite, then turn immediately right onto Rue de Vaux. Pass by the posts and the school car park. After a very short climb to the left, take the first right. Rue de la Tour Beaufort (reserved for residents) climbs gradually upwards. Enjoy the view of the valley. Pass the concrete blocks and bike down to the right to rejoin the old trunk road. At the traffic light, climb off your bike. Walk a short distance along the left of the road until you come to Rue des Chalvergnes on your left.
