When you arrive at Superdévoluy, take the third exit at the roundabout, then take the road that passes in front of the Hôtel des Chardonnelles and heads south.
Park near the Chalets Margot, in a small car park on the left-hand side of the road in a bend.
(S/E) Head south following theGRP® Tour du Dévoluy trail, which starts just below the car park (red and yellow markings on a lamppost). Continue to the junction with a wide grassy path.
(1) Continue left on theGRP® to climb the wooded embankment. Arrive at the Clot des Millioux crossroads.
(2) Take the path on the right, heading south-west. There are several signposts. Follow the signs for Combe de la Corne. You will reach a grassy slope towards small pass de Prapérouse.
(3) Turn right towards the south-west. After a hairpin bend, continue without a path on a grassy, slightly wooded slope. Stay on the top part and reach the edge of this wooded area.
(4) Towards the last trees, look for a weak spot in the rocky outcrops. The valley where the Pic de Bure cable car is located is clearly visible. A horizontal or very slight descent will take you to the bottom of the valley, where you will find an excellent path, which is once again the GRP®.
Note: this starting point for the traverse is the only place where it can be tricky to find the right path. Here are a few landmarks: when you turn left, you are roughly at the C in the word Chabrières on the map; visually, you are roughly at the same altitude as the middle of the last cable car pillar; finally, a black water pipe from a sheepfold crosses almost exactly where you need to pass.
(5) Now follow this very good path uphill. A little above 1900m, make a 90° turn to the left. You will reach a pass, which is a crossroads of paths.
(6) Continue south, turning right. The well-marked path leads to the entrance to Combe Ratin.
(7) Enter this valley, where the path becomes a little tricky as it is uneven and crosses steep slopes. However, this section is short and easy to navigate. Then follow a path that is almost always in good condition. You will arrive on the plateau, not far from the cable car arrival buildings.
(8) Turn completely left and begin a long traverse towards the south-east. You will reach the pass where the path crosses the Combe d'Aurouze trail.
(9) Continue straight ahead, ignoring the path on the right, and reach the summit of Pic de Bure.
(10) Retrace your steps back to the observatory buildings.
(8) Go around them on the left. Be very careful here as the plateau is very flat. Do not be tempted to head towards Combe de Cluse on the left, but continue on the right, north-west, on very good tracks. You will reach another tricky section, equipped with a few cables, at Pas de la Fenêtre.
(11) The start is a little exposed above a rocky outcrop. Descend a steep but well-equipped slope that leads to the top of the Superdévoluy resort. Join the GRP® variant.
(12) Follow theGRP®, heading diagonally up the slope towards the north, make one or two hairpin bends and reach the top of the Sommarel ski lifts.
(13) Leave theGRP® here and take the gentle slopes on the right, closest to the cliffs that support the Pied Gros de Saint-Étienne. Climb a few metres to reach a small pass between the northern slopes of the Pied Gros and the Bonnet Rouge.
(14) From there, descend as best you can down the large slopes that lead to the Bergerie de Pied Gros, passing not far from the Trous de la Tune, then quickly rejoin the first crossroads on the way there.
(1) Take theGRP® on the left to return to the car park (S/E).
