Access: From Embrun, take the N2094 in the town centre towards Briançon-Gap, then just before the post office, turn right and follow the D465 towards Caléyère. Pass the hamlet and then the castle of the same name. Continue to the car park on the right-hand side of the road. It is about 10 km from the Embrun post office on a fully paved road.
(S/E) From the car park, take the track on the left for about 30 metres towards Mont Guillaume via Pré Clos. At the sign, turn right onto the path towards Mont Guillaume and Chapelle des Séyères for 200 metres.
(1) At the intersection and sign, go straight ahead towards the chapel. The path climbs through a thick forest of larch trees to reach a lane.
(2) At the sign, turn 90° to the left, still heading towards the Chapelle des Séyères and Mont Guillaume. Follow this lane for about 80 metres.
(3) At the next sign, continue in the same south-westerly direction and follow this lane for 980 metres until you reach the next intersection.
(4) Leave the lane and turn right onto the path towards Mont Guillaume. The path climbs gently up the hillside through a forest of larch and Scots pine trees, then crosses a wide dirt track. Our path eventually turns into a lane.
From here, pay close attention. A cairn on the left side of the lane marks the starting point of a small path that branches off at an angle.
(5) At the cairn, take this path on the left. It climbs for about 20 metres. Cross the wide dirt track and continue along the path until you reach the next well-marked intersection.
(6) At the sign, take a sharp left turn onto the Widman trail towards Mont Guillaume.
A little further on, when you reach a crossroads (path, lane) that is not shown on the IGN map, continue in the same direction. The lane turns into a path and crosses a rocky area before coming out at another signposted crossroads.
(7) Take the lane on the left, cross the Sainte-Marthe torrent, and continue to the Chapelle des Séyères chapel, then immediately after, in the same direction, to the fountain of the same name. Then take the trail south to the next intersection.
(8) At the sign, take the hairpin turn to the right towards Mont Guillaume. This path leaves the forest and climbs through rhododendron bushes and piles of boulders. Take the hairpin turn to the left and cross the hillside (southeast).
(9) To make the final ascent to the summit, at the intersection, take the path on the right, which climbs more gently. After a hairpin bend, the path continues along the side of the north ridge of the summit, and it is not uncommon to encounter some snowfields at the beginning of the season. A final, steeper climb takes you to the summit cross and the Chapelle du Mont Guillaume.
(10) Return by the same route to the car park (S/E).
