Guidebook with maps/step-by-step
1 - When you arrive at the car park, take the path uphill signposted Pic St Barthélemy, which leads to the Atlantic salmon breeding pond (please note: swimming and fishing are prohibited).
2 - Go around the pond on the left, following the track through the beech forest.
3 - Continue climbing until you reach the old barracks of the talc quarry, pass them and climb through the forest to the ridges (Monts d'Olmes viewpoint). (Yellow signposts).
4 - Follow the ridge to the left until you reach the post, then turn right towards the summit.
5 - At the crossroads, turn left and descend towards the scree.
6 - Climb under the stone pines until you reach the Trout Pond.
7 - Turn left and climb again among the stone pines and then over the scree.
8 - At the junction with the GR del Macizo de Tabe, turn right (yellow and red signs). Caution: wet area
9 - Skirt around the Diablo pond from a distance. Once past the pond, keep to the left and approach the snowfields below the Soularac peak.
10 - Climb up a small chimney that leads just below the upper ponds, which you will go around on the right.
11 - Climb up to the Trou de L'Ours pass and finish the ascent to Saint-Barthélemy peak via the fairly steep ridge. You can choose to descend via the same route or via the ridges to the north until you find the path you took on the way up, always following the ridge. Descend to the car park.
Variation: There is a variation for the ascent: leave the D909 directly, 2 km after the track junction. Climb through the forest, pass the Orri forest house, continue through the forest and, once at the edge, turn left to climb the ridges.
