(S) Next to La Nouvelle school, take theGR® R1, marked in red and white, which climbs towards the Col des Bœufs.
Continue across the Plaine des Tamarins to reach the junction of the Col des Bœufs and the Fork in the road.
(1) Then turn right towards the Col de la Fourche and head for it.
(2) Leave theGR® here and turn right.
Take care here: there is a steep, vertiginous section for a few metres as soon as you begin the descent.
Follow the path as it enters the Ravine des Merles. Cross a footbridge over the Ravine Pont du Chien.
(3) Cross it and continue the descent via a series of hairpin bends to rejoin the Ravine du Grand Sable and the junction with the GRR1.
(4) Cross the ravine and turn right onto the GRR1. Walk on level ground across the Grand Sable plain. At the shelter, turn left. The path then winds twice before emerging into the Ravine Camp d’Henri.
(5) Continue along theGR® and, after a long descent, you’ll reach a junction of paths past the houses at Mare d’Affouches.
(6) Keep to the right on theGR®. You’ll soon come to a road; follow it to the junction with a path near the Anciens Thermes d’Hell Bourg.
(7) Turn left and walk through Hell Bourg to return to the starting point (E).
Then simply follow the tarmac road back up to Hell-Bourg.
