At the Abeilles pass (244m), on the left side of the road, choose the path closed to traffic by a barrier (hiking sign). It leaves the forest, reveals the summit of the Rhune and reaches a clear height. Descend 30m to a small grassy pass (266m), then follow the wide path that goes up to the right, through the ferns. Cross the summit plateau of Aire Leku, pass by a ruin, then go down a path that bends to the left. At the intersection of the Y-shaped paths (252m), take care to choose the one on the left, in the woods. At the second Y-shaped intersection, go left again, uphill. At the third one, go down to the right.
