Continue along the entire ridge on a very clear path. It goes up and gets close to a borderland. Go up Soum du Coutchet de Planté After the mountain pass, go down a path and get back onto the road. Go along the tarmac for 100m and walk left, staying on the ridge line. The path disappears so go straight up until you reach the edge of a forest. Follow the fir forest towards Pic d'Anie on the right. Get back on a path, still on the edge of the forest, and go down to reach a track. Walk until you reach the Col de Serre Benou.
