(S) From the Thabor refuge, rejoin theGRP® trail, descending slightly until you reach the junction with theGR®5, marked in red and white.
(1) Turn right, continuing along theGR®5for a few metres. Pass a small lake on the right, then walk past a cross, the Col de la Vallée Étroite and the Sainte-Marguerite pass.
At the next junction, turn right, leaving theGR®5, and continue on theGR®57, which skirts the mountain range on your right. You will see Mont Thabor opposite and the Cheval Blanc on your right. Continue to the rocky ridge.
(2) Cross to the left bank of Lac du Peyron. Begin the ascent of the Chances du Peyron, a pass between the rocky ridge on your right and the Grand Seru on your left. This massif consists of a very imposing and steep rocky ridge. Continue to the Col des Méandes.
(3) Take the path on the right and begin the very difficult ascent of the Thabor.
Take care on this treacherous path, where numerous snowfields remained at the start of August.
According to the refuge wardens, there was still nearly a metre of snow at the Col des Méandes in early July.
The temperature drops rapidly and the effects of the altitude are quickly felt as you climb. Wayside shrines line the path to the summit, where you’ll find the Chapel of Notre-Dame des Sept Douleurs. The final few metres are particularly difficult.
(4) At the summit of Thabor, the view offers a 360° panorama which, at this altitude, gives the feeling of being on top of the world. Retrace your steps back to the Col des Méandes, taking great care on the steep descent.
(3) At the pass, take theGR® on your right, which descends to Les Granges de la Vallée Étroite with a 1,000m drop.
(5) Leave theGR®57on your right and continue straight on, with the Grand Seru and Petit Seru on your left. Continue straight on, still heading towards Les Granges de la Vallée Étroite.
(6) Cross the footbridge over the stream at Prat du Plan. Reach the hamlet of Prat du Plan.
(7) Continue straight on, ignoring the path branching off to the left. Follow the wide path downwards, with the farm, La Maison des Chamois, on your left. As you descend, you will see a beautiful waterfall on your left. Reach the bottom of the valley at the hamlet of Le Pont de la Fonderie.
(8) Join theGR® 5 and 57.
Turn right and head for the hamlet of Les Granges de la Vallée Étroite, which marks the end of this fabulous stage. Two mountain huts await you there; see the note in the ‘Practical Information’ section (9), (E).
