From Arvieux, take the D902 towards Col d'Izoard to Brunissard. At the entrance to the village, take the small road on the left that follows theGR®5towards Pré Premier, Chalets de Clapeyto. Pass the campsite and park at the next car park at Pré des Vaches.
(S/E) From the car park, head west following theGR®5(red and white markings). Follow the track that joins the Rivière torrent at Pré Premier, then climbs in hairpin bends to an altitude of 2,142 metres (direction sign).
(1) At the sign, leave the track and climb to your right (north-west) via theGR®5towards the Col des Ayes. You will see the pass with the Pic de l'Aiguiller to its left and the Pic de Beaudouis to its right.
(2) At Col des Ayes, follow the ridge to the right (east then north-east). Pass under two small gendarmes before reaching a plateau on the western ridge of Pic de Beaudouis.
(3) Head east-southeast and take the path that crosses the imposing west-southwest face of Pic de Beaudouis. This path takes you to the southern ridge of the peak, which you will need to climb, following the cairns to the summit.
(4) The return journey follows the same route in reverse. However, it is possible to cut across the middle of the traverse by descending directly south into the scree without going back via the Col des Ayes (remain cautious in the scree). Return to the car park where you started (S/E).
