From Sare, take the D306 road (towards the Sare Caves). Ignore the road to the caves which branches off to the left and continue towards the Etxola wildlife park. Take the next road on the left, pass the wildlife park and continue along the track * until you reach a sheepfold.
(S/E) Take the wide path heading south. The path winds through the forest and emerges into a meadow, eventually reaching a crossroads higher up at the foot of a stone watchtower.
(1) Turn left, heading east, onto the path leading to the foot of the stone tower.
Continue south-east and then east along the path which climbs to the pass at the foot of Saiberri.
(2) Follow the path along the ridge to climb quickly to the summit.
(3) Take the same path back to return to the car park (S/E).
