Stage11 of this route. One of the most beautiful and challenging stages of the route, featuring the Aup Martin pass at 2,700 metres and the Pas de la Cavale, the highest point ofthe GR® 54. This stage demands the utmost vigilance and experience of high-mountain hiking. The views are absolutely stunning and incredibly wild. We took the shuttle bus to avoid the 8 km of tarmac road to the car park at Entre-les-Aigues.

The hike begins with the ascent of the Pas de la Cavale, which rises to an altitude of 2,735 metres. After this climb, you will reach the Pré de la Chaumette refuge. From there, another climb will take you along the imposing Sirac, passing through the Vallette, Gouiran and Vallonpierre passes. The route ends at the Vallonpierre refuge.

Access from the alpine hamlet of Moussière to the bivouac area located between the Selle and Crousas mountain pastures. This mountain pasture overlooks the Cabane Sainte-Marie, where the sheep are kept at night.

This pleasant second day begins with a climb to the Col de Moussière before passing by the very pleasant Lac du Lauzet, then taking the long forest track back to the Moussière car park.

The12th stage of this route features three passes to cross, the last of which is particularly technical and difficult. The panoramic views remain as exceptional as ever, with vistas of the majestic Chaillol, the Sirac and the Champoléon valley. The refuge is set in lush greenery at the bottom of a cirque at the foot of the Sirac and on the shores of the magnificent Lac de Vallonpierre. A campsite in a beautiful meadow at the foot of the Sirac, with a splendid view of the lake.

From Prapic to Dormillouse via the Fressinières Pass. Please note: the height difference is only 1200 m.

From the Vallonpierre refuge, the hike takes you to the Rif du Sap chapel, then to the charming village of La Chapelle-en-Valgaudémar, where you can stop for refreshments at a local grocery store. The route then crosses the Valgaudémar National Forest before reaching the magnificent lakes of Pétarel and Sebeyras.
