Departure from the former school in Sorendal, in the commune of Hautes Rivières.
10 May 2018: The GR®16 and GR®12C routes have recently been modified by the FFRP to form a single GR® route in this hiking area.
The route follows some sections of marked trails (PR® and GR®) but is not marked in its entirety.
(S/E) With your back to the old school, take Rue du Falligeois. Shortly after the last house, take the path on the right, then immediately left. The trail climbs steeply, then joins a tarmac road. This is part of the Transemoisienne. Follow it towards Les Hautes Rivières until you reach the top of Rue du Commodo, about a hundred metres after a barrier.
(1) Do not go down this street, but turn right to climb eastwards before continuing left towards the north (yellow markings). The path climbs up to Roche Margot.
(2) Turn left to reach the table and viewpoint overlooking the village of Hautes Rivières. After the viewpoint, return to the original path and turn left. The path descends slightly, then veers left to begin a steep descent before turning left again. Continue to a crossroads near the cemetery.
(3) Descend to the right, pass by the cemetery and join the access road to it. Turn right and continue in the same direction until you reach the Linchamps road (D13).
(4) Cross it carefully and take Rue du Petit Ohan opposite. At the end of this street, turn right, then immediately left and finally right again. The GR® trail, which follows the Transemoisienne, climbs gently towards the ridge of Château de Linchamps. Before the top of the climb, you will arrive at La Voye à l'Âne (signpost).
(5) Turn right towards La Dauphinée and continue to a crossroads.
(6) Turn left onto a forest road towards Champ Bernard, where you will find a table and shelter for a short break. Continue along the tarmac road for 150 metres, then turn left and follow the GR® to the Liris viewpoint, which offers beautiful views of Nohan.
(7) Retrace your steps for about 100 metres and take the first path on the left, then immediately turn left again. The path descends steeply and joins the Ruisseau du Nantanru, a tributary of the Semoy, and follows the right bank of the stream. As you approach the confluence with the Semoy, keep to the left to reach the confluence of the stream with the Semoy.
(8) Head left onto the Transsemoisienne and take the first path on the right to reach the Pont de Nohan.
(9) After crossing the bridge, go through the barrier on the left and climb up the embankment on the right. Follow the path to the old Chemin de Thilay in Nohan.
(10) Turn right, pass a path on the right (towards Naux) and reach a crossroads (elevation 223).
(11) Go up to the left on the path that joins a high-voltage power line and runs alongside it. Continue to the Chemin de Thilay in Robessart, located at the top of the climb before a rocky passage.
(12) Take the small path to the top of the Dames de Semoy (lovely view of Nohan).
(13) Turn right without losing altitude onto a small path that leads to a gas line. Follow the path on the left that runs alongside the gas line, pass the paragliding launch area and then a telecommunications pylon. Next, follow a steep descent to reach the Hatrelle crossroads.
(14) Follow the GR® trail to the right, cross a road (D13) and continue straight ahead on the GR® trail until you reach Rue de la Semoy in Failloué.
(15) Turn right onto this street, then left to cross the bridge over the Semoy. Join Rue de l'Industrie and follow it to the right, then turn left onto Rue de l'École, the former Sorendal school (S/E).
