Next to Oulettes de Gaube refuge (2158 m) a bridge crosses to the left bank of the stream, where a signpost indicates the direction to follow. The route covers some flat land next to the meadow and soon starts to climb towards the pass. The path is more obvious at this point with some painted markings and relentlessly snakes up the slope to reach Mulos pass (2594 m).
From this pass we can see the path that crosses the long rocky outcrop that overlooks the valley. To take this path we need to descend a few metres along the path until we see a path marked with cairns leading to the right (2522 m) (crossing with route 19). To the left the path descends towards the valley and we continue to follow the painted markings coming from the refuge. We now have to ignore the markings and find the cairns heading off to the right and follow a horizontal path gently taking us round to Col d'Arratille or Coth d'Arratilha (2526 m) (crossing with route 20).
The painted markings appear again. We then border round Lac du Col d'Arratille (2507 m) next to the pass. At the exit from the rock field the markings disappear once again but the cairns and well-trodden path make it easy to follow. The walk then heads down the valley, following the left bank of Lou d'Arratilja (2247 m). A small bridge leads us across the outlet from the lake and the path moves away from the river to cross a rocky outcrop. Once over the outcrop we return to the banks of the river and follow it to Gaba d'Arratilha. After crossing a bridge (1813 m) (crossing with route 03), the path joins the route between Pont d'Espagne and Wallon-Marcadau refuge (1865 m). We then follow this path to the left and, after a short climb, we arrive at the refuge.
