(S/E) From the resort car park, theGR®Tourdu Dévoluy route is marked in red and white. It climbs up the ski slopes, starting to the right of the La Roche ski lift, first through woods, then through more sparse vegetation. Reach the top of the Pélourenk chairlift.
(1) Take the opportunity to admire the two lakes (water reservoirs). TheGR® continues through a slightly more arid landscape. Arrive at the top of the Festoure chairlift.
(2) After joining the path that starts at La Joue du Loup and reaches the top of the Sommarel chairlift, continue on theGR® trail, which passes under the Sommarel rock and reaches "La Fenêtre" at the end of the Plattes d'Agnieres ski lift.
(3) Climb La Pierra to reach the handrail that leads to the Bure plateau. In good weather, it is impossible to get lost, as theGR® is clearly marked and heads south-east to the Plateau de Bure Observatory.
(4) Keep to the far left towards the east-southeast, still on the GR® marked in yellow/red. After about 1.4 km, it bends to the south-southwest.
(5) Leave the GR® and follow the path which, after a few bends on a slightly steeper slope, leads to the summit of Pic de Bure.
(6) Enjoy the view from the summit, then descend the path to the junction to rejoin the GR®.
(5) The return journey is via Combe Ratin (which you take near the upper cable car station). To do this, take theGR® and then leave it after about 500 m for a well-marked path on the right that is often used.
At the bottom of the valley, go around a rocky outcrop, keeping to the right.
(7) The descent continues. Leave the Corne valley and walk under the cable car cable to reach a wide path.
(8) Turn left, heading north, towards the small pass of Prapérouse. Continue to the large crossroads before "Les Vallonnettes".
(9) Turn left and head for the Super Dévoluy car parks (S/E).
