Park the car on the Sarrat de Gaye road, on the right, in a lay-by lined with small rocks and before a right-hand bend.
(S/E) Head due south along a wide track towards the Courtalets huts.
(1) Cross a stream and go round these huts on the left.
(2). Continue due south. You will need to zigzag through the snow-covered mountain pastures towards the first hillock (1596 m).
(3) Go round it on the left. Now head south-west towards the rocks marking the summit of La Bèque at 1,721m. Admire the landscape with views of the Pic de Midi de Bigorre. The 360° view is spectacular.
(4) From the summit, head south-west then turn east quickly, slightly south of the ascent route, then due north-east.
(5) At around 1,600 m, turn right towards the south-east, following a gentle ridge, and descend due east towards the Courtaou de Sarroua, which can be seen at the bottom of the valley.
The slope is gentle and perfectly passable on snowshoes. A short stop at this mountain hut (a summer pasture building) provides a chance to rest.
(6). Cross the La Gaoubole stream, turn right at a 90° angle and head due south, climbing to cross the north-south ridge that separates the two valleys.
At a crossroads, turn sharply left, heading north-east, and head for the Courtaou des Esclozes sheepfold overlooking the La Gaoube torrent. Another break may be in order.
(7) From this sheepfold, continue north-east along a track that runs slightly above the Courtaou.
(8) Reach the end of the Sarroua ridge and turn left, heading due west, following the track.
(9) Cross La Guaoubole and turn right heading due north.
(1). Follow this track to the car (S/E).
