(S/E) The start is at the small car park next to the Goihena mill. Follow the road along the Susselgue stream, keeping to the right-hand lane, passing the fish farm and a second mill.
(1) Turn right and continue up the tarmac road to reach Bordaberria.
(2) Turn left onto the path that winds its way up through the forest. The entire ascent is along this wide path, which is accessible to both two- and four-wheeled vehicles.
(3) At the three-way junction, turn right, continue along the track that runs alongside a small gorge and resume the climb.
(4) At the next fork, keep slightly to the left and finish the climb after passing a hut on the right.
(5) To the left, for those who fancy it, is Pic Losco. Our path takes us to the right, along the ridges, to the Harriauzkia house.
(6) Continue to follow the path along these ridges, with Pic Harribeltzeta in view to the north-west. The path becomes a track up to the peak but remains very easy to follow.
(7) From the peak, simply take the path that descends south-west at first, then, after a hairpin bend, descends steeply north-north-east, then east. Just stay on this path, which goes round a few houses.
(2) Follow the final section of the route in the opposite direction to the outward journey to return to the car park (S/E).
