The proposed itinerary takes sections of routes marked in Blue (France Camping Club) and Yellow (Barbaricum itinerary). To reach the Loizerolle farm, however, there is no signposting.
(S/E) From the town hall, take the D114 West.
(1) Just before a bend in the road to the left (picnic table and Camping Club de France itinerary information panel), turn right onto an uphill path, marked in Blue. Go straight ahead at the first junction, do the same at the second and join a wide path at a hairpin bend. This part of the itinerary, on a ridge, offers some wonderful views.
(2) Turn right uphill.
(3) Pass the "Trou-qui-Fume" and reach a small tarmac road.
(4) Take this road on the left, downhill towards the hamlet of Vaux lès Grenant, where you find the D114.
(5) Follow the road to the right, then, just before the end of the hamlet, turn left, uphill, and go straight on until you reach a crossroads with several paths.
(6) Go right for a few metres, then take the first path also on the right. When you reach a line (hunting stands), turn left at 90°, slightly uphill. Leave the forest and turn right onto a small tarmac road. Turn left onto the road.
(7) At the crossroads (shed on the left), turn right and continue to the Loizerolle farm.
(8) Retrace your steps to the aforementioned shed.
(7) Go straight ahead, ignoring the road you came by and a wide track on the right. At the crossroads (555m), go straight ahead on a white track.
(6) Continue straight on, passing an imposing hunting hut and continuing downhill.
(9) Leave the white path and take a Yellow path on the right. Follow the signs to the Coteaux de Martigny lookout.
(10) The path then winds through the forest, eventually descending to reach a Blue signpost.
(11) Turn left and follow the double signposting to a sort of pass at the point just before 455.
(12) Leave the Yellow markings and take the Blue route, which is very steep at first. Pass by the Dame à Massiette and return to the D114, which you follow to the right. Cross the ruisseau de la Gyronde (stream) and return to the original crossroads (picnic table).
(1) All that remains is to retrace your steps to return to the town hall car park (S/E).
