Cross carefully and enjoy the superb view of the Ossau valley and the Pyrenees. Go up opposite the Paillassa path for 400m.
Arrive at the crossroads between Chemin Paillassa and Chemin d'Aliou, the highest point of the walk (cleaning containers). Then turn right, north, for 2 km, a gently sloping path in the pretty wood of Gelos.
Halfway, you can admire the Château de "Tout-y-croît" on the left, a private property dating from the 16th century.
