Departure from the small car park in front of the church of Saint-Georges-de-Gréhaigne.
(S/E) Turn your back on the church and go down the street on the left. Take the first street on the left and follow the path. On the road, turn right.
(1) When you reach the road (D797), turn left and, a little further on, take the path on the right. Continue straight ahead until you reach the first crossroads.
(2) Take the road on the right, leaving the buildings on your left, and stay on the left after these buildings until you reach the second crossroads.
(3) Head south-east to the right to reach Le Pas au Bœuf and head towards the Moidrey farm on the left. Continue straight ahead until you reach the next road on the left.
(4) Turn left (a wayside cross on the left marks the crossroads). Continue straight ahead until you reach the stream on the left. Turn in this direction and follow the stream which leads to the Greenway. Pass through the sluice gate and follow the sign for bicycles indicating Saint-Malo on the left. Follow the tree-lined path, ignoring two crossroads.
(5) At the third junction, take the path on the left, which leaves the trees. Turn right and continue to the junction with the D797.
(6) Cross it and continue straight ahead. You will arrive at a place called Chanel.
(7) At the crossroads, leave Roz-sur-Couesnon on your right and head towards the centre of the hamlet on your left. At the first crossroads, take the road on your right and climb the slightly steep hill.
(8) At the top of the hill, take the road on the left, which turns into a path. There is a beautiful view of the white marsh. Continue along the path, which gradually turns into a trail. Follow it as it veers east and runs alongside the N172 (you can't see it, but you can hear it). The trail passes through the undergrowth and descends to a farm track.
(9) Take it on the left to reach a road and turn right. Continue straight on the road to reach Rue du Puits in Saint-Georges-de-Gréhaigne.
(10) At the third crossroads, look for the bell tower and take the second road on the right to reach the car park (S/E).
