Park in the car park at the Maison de la Montagne in the village of Le Claux.
(S/E) Join theGR® 400, accessible via a small road to the right of the house. TheGR® passes by the campsite and takes you up into the hills via a very narrow country lane. Walk past the hamlets of La Jarrige and Lavialle. After the bend at Lavialle, you’ll come to a crossroads of footpaths.
(1) Keep to the right on theGR®, following the red and white markings, and follow an easy climb to the Ruisseau de la Blatte.
(2) Cross the stream and continue uphill to reach another junction at a hairpin bend.
(3) Keep to the right on theGR® and continue through the Bois de Nolly Lavialle. Walk along a path alternating between short descents and ascents to reach the Col de Serre.
(4) Continue straight ahead on theGR® along a path running parallel to the D680. You’ll rejoin the road at the Burons d’Eylac junction.
(5) Carry on straight ahead to reach the Col d’Eylac quickly.
(6) Return via the same route to the burons.
(5) Leave theGR® and turn left to begin a long, easy descent. Follow a wide right-hand circular loop through the Bois Marty to reach a stream below the Roc des Chamois.
(7) Continue along this well-marked path until you reach the Ruisseau de Ricou la Peyre.
(8) Continue the descent and, after two hairpin bends, reach the junction with theGR®400.
(9) Turn right onto the GR®400, follow it past the Chaumilloux car park and then the hamlet of Lascourt. You’ll come to a crossroads with a wayside shrine here.
(10) Keep to the right on theGR® and walk round the Étang de Lascourt. You will then reach the hamlet of Lespinette; turn left to return to the car park at the Maison de la Montagne au Claux (S/E).
