In Oloron-Sainte-Marie, take the Route du Somport. Before the tunnel, and just opposite the road leading up to the pass, turn right onto the small Route des Forges d’Abel. From there, head towards the power station and then take the Route Forestière d’Espélunguère to the car park (altitude 1,350 m).
(S/E) Take the path that branches off to the left of several information boards. It climbs south-west and passes to the right of a waterfall below. The path rejoins the forest track you left at the car park.
(1) Cross the track and take a path opposite, which cuts across three hairpin bends in succession to rejoin the track at around 1,480 m.
(2) Follow it north-east through the forest, emerging at around 1,580 m. Stunning views of the Pic du Midi d’Ossau. Continue to the Col de la Mousquère (1,628 m): views of the Cabane de Grosse.
(3) Continue climbing north-west to reach the hut at 1,630 m.
(4) Go round the hut on the right. The gradient steepens to reach the 1909 m high point: view of the Lapachouaou valley.
(5) The path veers sharply left towards the west and then north-west, running almost flat to the Col de Lapachouaou, 1891 m.
(6) The path continues horizontally along the slope of Montagne de Banasse. Pass above the Cabane de Gourgue Sec and reach the junction with the path coming from Aubise (1,880 m).
(7) Continue along the well-marked path. It begins to climb gently again to reach the area above the lake, then descends to the lakeside at an elevation of 1987 m.
(8) Continue on to reach the refuge (which is due to reopen after renovation work in summer 2023). After a pleasant rest, return via the same route to the Espélunguère car park (S/E).
