To get to the starting point, from Noirétable follow the D53 towards Vollore-Montagne, then the D101 towards La Chamba. Then follow theD1015 to the right and head towards Notre-Dame de l'Hermitage.
(S/E) With your back to the buildings, take theGR® 3 (parallel to theD1015) heading south. A barrier marks the entrance to the path leading to the chapels.
(1) Cross the stream "Le Lignon" and continue until you reach a small clearing. Turn left to reach the Croix Saint-Guillaume.
(2) Facing the cross, turn a quarter turn to the right (east) and head towards the entrance to the path leading to the Lit de la Vierge (path located between the departmental boundary and theGR® 3 on the IGN map). The entrance to the path is marked on the left by a tree trunk painted blue and on the right by a tree trunk bearing the number 1 in red on a white square background.
Follow the path for about 400 metres, now marked by blue ribbons attached to the branches and/or blue marks on the tree trunks. Turn right (blue arrow) and you will reach the chaos in about 100 metres.
A sign (at last!) at the foot of the granite chaos indicates "Lit de la Vierge" (Virgin's Bed), points out the panoramic view and warns of the slippery nature of the rocks. In dry weather, you still need to use your hands.
Climb to the top via a fairly steep ascent with narrow passages between the boulders. At the top, admire the 360° panoramic view.
(3) Descend carefully and return to Notre-Dame de l'Hermitage via the same route (S/E).

). If you are still there at the moment, would you mind telling the owner that, as promised, I have advertised her lodge, which is well worth it (stay from 13 to 20 July - 4 people from the Pyrénées-Atlantiques)?
