In Allan, follow the signs for "Vieux village" (Old Village), go to the end of the road and park just before the barrier.
(S/E) Go through this barrier and climb up to the ruins of the old village. Enter the old village through the south gate, just in front of a barrier erected in 2016 to prevent access to a dangerous path. Cross the village and join the old path from before 2016 on the right. Go down this path on the left to the Fontvielle-Est crossroads.
(1) Go up to the left.
(2) After a house, at the fork, turn left and cross an oak forest.
(3) At the clearing, turn left and then, 100 metres further on, climb up to the right under the pine trees until you reach the Échinière crossroads.
(4) Turn left for 200 metres and then right at the first fork. Continue straight ahead, keeping to the same south-easterly direction. Pass the Jamot crossroads and continue right on the track to climb up to the Claves plateau.
(5) Leave the track and take a path that descends to the left through the box trees. Look for a "VVT 3" route on your right and follow it to Fontagrèse (elevation 250). Turn left and join the D4 near a house.
(6) Turn right and, after the bridge, take the path on the left that climbs between the two houses, to the right of the garden of the first one. It was not marked when we passed by. Climb up to the castle of Rochefort-en-Valdaine. Go around the site on the left and reach the entrance to the chapel. Go down the stairs.
(7) Take the path on the left. Continue left at the next crossroads and you will reach the Serre Pointu crossroads.
(8) Turn left. Join the access road to Durand, turn left and then left again a hundred metres further on towards Grel. Join the D4.
(9) Take the D4 on the left, cross the bridge and turn right onto the path.
(10) At the Jamot road junction, turn right. Climb for about 350 metres and look for a small unmarked path on the right (yellow cross).
(11) Turn right and follow the track, which curves sharply to the left and heads west. Pass the Fontaine d'Artur fountain, join the Chemin de Moïse and follow it to the left until you reach the first junction.
(12) Follow the path on the right to the Maison de la Motte, where you will join the Chemin de la Biscarat.
(13) Continue straight ahead, crossing a wildlife refuge. Leave the road on your right that joins the D126 linking Allan to Espeluche and continue for about 200 metres.
(14) Take the small road on the left, which quickly becomes a path and climbs towards the old village of Allan.
(15) Turn right to go around it, rejoin the outward route and turn right again to return to the barrier and the car park (S/E).
