From LE RIOU VERT, head for the Fromage pass via the Riou Vert valley, up through the forest to the footbridge. From the pass, walk up to the observatory (a former military lookout post) for a beautiful 360° view over the Ruine Blanche ravine, the Riou Vert valley, the Ceillac valley and Font Sancte. The crossing continues along ridges to the Bramousse pass, then down to Les Sagnes. From there, head for the Souillet pass and the Bramousse chalets before returning to BRAMOUSSE via the GR58 trail.
