Park at the Sainte-Marie-de-Campan town hall annex.
(S/E) Pass under a porch (due north). At the end of the porch (10m), climb up to the left. Go through a gate and climb up to the north-west. After 500m, head for the water reservoir on your left. Go around the reservoir on the right.
(1) Head south. Go through the gates (making sure to close them behind you). Continue climbing due south. Take a pretty path that runs alongside some beautiful, well-maintained barns. When you reach the last barn, do not cross this private property (yellow cross). Descend slightly to your left and follow a flat path below that runs parallel to the property. Continue for 170 metres.
(2) At the intersection with a track, take a wide path on your right that climbs and leads you to a large gate (you are at the other end of the property). Turn left onto the well-marked south-west path that climbs. Continue for 200m.
(3) Take the path that climbs south on your left (towards Courtaou d'Empièye). Continue climbing this path through the summer pastures heading south. Arrive at Courtaou (1,450m).
(4) Follow the path that climbs up the grassy ridge, heading south-west.
(5) At the 1513m mark (boundary stone), the path turns gently west. Continue climbing along this ridge. Pass to the right of the 1711m altitude.
(6) Arrive at Pla de la Serre (1746m). Already, you can enjoy a beautiful landscape with a view of the forward chain of the Central Pyrenees. At the end of this plateau, take a path that heads southwest, climbing slightly, then remains level to bypass Soum de Hailla.
(7) At Col Dé Bén, at an altitude of 1,843 metres, turn completely north-east. Continue climbing.
(8) You will reach the summit of Le Soum de Hailla (1,889 metres).
You can enjoy a well-deserved rest while taking in the spectacular view of the Pyrenees. Now, start thinking about the return journey, heading due east.
You must descend directly north, following another grassy ridge. At around 1650m, the path heads east.
If in doubt, turn back and descend via the same route.
(9) At around 1550m, at a sort of pass, the path heads north again (the path that goes around to the east leads back to Courtaou d'Empièye). Continue descending.
(10) Arrive at Clot des Artigous (1,405 metres). The path gently heads northeast.
(11) Arrive at Burros (1354m). Continue descending along the grassy ridge.
(12) Arrive at Cabanettes (1235m). From there, a pretty, well-marked path heads south. This path descends.
(13) Arrive at a place called Le Courbet. There are still yellow markings, follow them and cross the small stream La May d'Escaret (1113m). Cross this stream again and follow a small water supply canal on the left bank. This canal will take you to this morning's junction (Courtaou d'Empièye).
(3). Follow the morning's path in the opposite direction. There is another small water supply canal, barns, gates, a water reservoir on the right, and a descent under the porch, then back to the cars (D:A).
