On the N85 road from Gap to Grenoble, between La Guinguette and Chauffayer, take the D57 to reach Le Glaizil. Take Rue du Pont towards the church and then the cemetery. Park in the car park near the cemetery (Rue de la Tour).
(S/E) From the car park, take Rue de la Tour eastwards, then Rue de l’Église and finally Rue du Chapeau de l’Évêque.
(1) Cross the D57L road to Gap, and continue straight ahead along Rue le Long du Riou, heading east-north-east, towards La Condamine and Les Meilières. Pass the first hairpin bend and stay on the main track, ignoring the turnings to the left and right. Pass a second hairpin bend, then reach a junction of dirt tracks.
(2) Take the Chemin des Meilières on the left, heading north-west. Continue until you reach the D57L road at the Torrent des Amars.
(3) Turn right, heading north-west, and walk carefully along the D57L road to reach the hamlet of Lesdiguières.
(4) Continue straight on along Rue du Château, which runs alongside the ruins of Lesdiguières Castle, marked by the passage under the south gate. Then pass through the north gate.
(5) Turn left onto the Chemin de la Vialette, heading west then north-west, to reach the forest.
(6) Head uphill straight ahead, ignoring the paths to the right and left. Pass a few small hairpin bends, then cross the Torrent de Lesdiguières twice. Take the path that bends sharply to the left to join a forest track.
(7) Take the track to the left, heading south-east, leaving behind the path that climbs to the Pic de Chauvet. Walk through the Souvestre forest along its eastern flank and cross the Torrent des Amars in a ravine. Climb back up to follow the eastern flank of the Sapet des Amars as far as the Mont Fort bend.
(8) Walk down the slope to the Ravin du Glaizil, cross the stream, then climb 50 metres to reach the start of a small path on the right.
(9) Take the path on the right, heading south-west, to leave the forest track and continue through the woodland. Winding its way up in a series of hairpin bends, this path climbs nearly 300 metres in altitude before turning north-west to cross the torrent just above the Pellegrin waterfall. Continue the ascent, heading north-north-east, to reach a path junction just before a rocky outcrop.
(10) Take the path on the left, heading north-west, to go round the rocks on the left and climb via a series of gentle switchbacks. The path then turns north-east to climb the rocky spur. Reach the summit of Mont Pellegrin and the Rocher Ferrand hut.
(11) Turn back, pass the waterfall, and descend the numerous hairpin bends to rejoin a forest track at the junction you passed on the way up.
(9) Turn right onto the track, heading south, to cross the Ruisseau du Glaizil and walk up the hillside to a junction with two paths.
(12) Head down to the left, heading north, to cross the Ruisseau du Glaizil once more, then join Rue de la Tour and follow it to the village. Pass under the ruined tower, then walk alongside the cemetery to reach the car park (S/E).
