Walk to the village of Zugarramurdi. Pass to the right of the church and, about a hundred metres further on, turn left onto the tarmac road towards Etxalar. Climb up to the pass.
(S/E) Take the path on the right heading west, ignoring the track that climbs up to the ridge at Mendibil. The path skirts round the top of a fenced meadow and reaches a junction.
(1) Keep to the right, ignoring the path that climbs up to the left, then pass over a woodland to reach the Ibaineta Pass. Along the way, you’ll need to climb over fences twice using stone steps.
(2) Ignore the path branching off to the right at a 90° angle and take the path on the right, which ascends diagonally towards the ridge. The path initially runs along the northern flank, then veers left to climb back up onto the ridge and reaches a three-way junction near a large cairn.
(3) Continue to the right, heading west, to the summit of Atxuria.
(4) Return to the three-way junction.
(3) Turn right and head down south-east along the path, which later veers left (east) and joins the Col d’Ibaineta.
(2) Follow the same path as on the way out to return to the car park (S/E).
