Starting Point: Cascade de l'Alpe du Grand Serre
Itinerary:
Head to the Cascade de l'Alpe du Grand Serre. From there, take the wide path on the right that climbs into the forest. After two switchbacks, you’ll reach an area known as les Plateaux (1470 m). Continue for a few hundred meters until you arrive at la Combe de la Blache at 1500 m (Danger sign). Continue straight, ignoring the path on the right. The ascent becomes steeper, and the trail makes several switchbacks as it crosses an open basin (keep your eyes open — chamois and roe deer are often spotted here). The path then makes more switchbacks and enters the forest again. You're almost there, watch for the fork on the right leading to the Cabane du Périmètre. You’ll arrive from above, and what a view! The entire Roizonne valley lies at your feet, with the Armet mountain range, the distant Obiou, the Tabor, and the ski area from an unusual angle.

Descent: You can return via the same path or continue for several hundred meters. Around le Périmètre (1600 m), take the trail that descends to the left. It will bring you back to le Clos des Jensannes, then to la Croix de la Blache, at the southern entrance of the resort near the war memorial.
