Parking in Saint-Cyr-sur-Morin, in a car park at a junction with the main road (D31), near the Seine-et-Marne museum. For access by public transport, see practical information.
No signposts
(S/E) Go up Rue des Montgoins (south-west). Ignore a street on the left and, at the fork immediately after, take the street on the right for just a few metres.
Yellow markings
(1) Leave the street and take a path heading due west. Descend gently through a grassy area and join a road (D31). Follow this road (west) for about 150 metres.
(2) Turn left onto a path that climbs through the undergrowth. At the junction with another path, turn right and continue west-southwest.
Red and white markings
(3) Continue straight ahead through the woods on theGR®11, heading west-northwest. When you reach a house near a stream, turn sharply right and walk alongside a campsite.
(4) Turn left at a right angle onto a fairly steep path. Cross the D207 road and continue uphill. Shortly before reaching another road, the path turns right, continues along the edge of the woods towards the north, then turns left to join the road as you approach Romény. Turn right and follow the road for a few dozen metres.
(5) Take the road that climbs to the left. After about 100 metres, turn right onto a path alongside some houses, which quickly becomes a lane that crosses a street and then the main road (D114). Continue in the same direction (north), cross one last street and take the path opposite, which runs alongside cultivated fields. After a left-hand bend, turn right and continue north. At a fork, take the right-hand path. Join another path coming from the right and reach a street at the entrance to Jouarre.
(6) Turn right at a right angle. After about 200 metres, take a path that branches off to the right and descends gently in a north-easterly direction.
(7) At the crossroads (elevation 95), ignore theGRP® (red and yellow markings) that branches off to the right and continue on theGR® which turns sharply to the left. After about 100 metres, turn right at a right angle. The path descends steeply, crosses a small road and then a larger one (D204), and ends at a third road. Turn right and then immediately left.
(8) Cross the Petit Morin and reach a square in Courcelles-sous-Jouarre.
No signposts
(9) Leave theGR® and head east on a small road (Rue des Pommières) that crosses Courcelles. At the edge of the village, the road (with little traffic) curves to the right and continues south to reach Vanry and rejoin a GRP®.
Red and yellow markings
(10) Cross Vanry and follow a path southwards that remains fairly flat, on the edge of the forest (on your left) and meadows (on your right). Reach Biercy.
No markings
(11) Leave theGRP® trail on your left and turn right onto the main street (Rue de la Ferme), which you follow south-west to the end of the village. Take a path that follows the course of the Petit Morin. Flat and heading south then east, the path runs alongside cultivated plots and meadows at the foot of a hill dominated by a farmhouse on the left. Shortly before reaching Archets (elevation 59), turn left at a right angle and reach a small road.
(12) Turn right and cross Archets.
(13) At the crossroads, turn right to cross the Petit Morin. Head for the D31, which you follow to the left to return to the starting point (S/E).
