In Oloron-Sainte-Marie, take the D134 towards the Col du Somport. The road bypasses Bedous and Accous. Then turn off to the right towards Lescun. Shortly afterwards, turn left onto the D339 towards Lhers. Pass a lodge on the left and continue along this road to Aumet. Car park on the right (1,140 m).
(S) Follow the road due south for 1.6 km to the Pourcibo hut.
(1) Continue along this road. There are several shortcuts you can take to avoid the hairpin bends that follow.
It’s best to pace yourself as the walk is quite long. You’ll arrive at the Cabane Det Caillau.
(2) Take a path that climbs to the right (signposted). It starts off through grassy terrain but soon becomes well-marked. It follows a circular route to the left before continuing to wind its way southwards up the mountain to a junction marked by a sign.
(3) Ignore the path on the left, which heads towards the huts and the Col de Souperret, and take the one on the right, towards the Col de Saoubathoù. The path continues southwards with a steady climb and reaches a flat section.
(4) A short rest. The path continues and, after several hairpin bends, reaches the junction with the path coming from the right and from the Col de Pau
(5) Turn left. The path follows a contour line more or less straight to the Col de Saoubathou (1949 m).
(6) Continue along the path (signpost) which follows a gentle contour line for about 1 km.
(7) Begin a descent of about 1 km to the Lapassa Hut and the junction for the Hotassy Hut and the Col de Lagréou.
(8) Keep to the right. The well-marked path will first begin a gentle climb, followed by a steeper ascent with a series of hairpin bends up to the refuge.
(9) Take full advantage of this idyllic spot, then return along the same route to (S/E).
