At Col Otxondo, take the road signposted Gorramendi. Pass Col d’Itzulegi and park 300 m further on.
(S/E) Take the middle path which passes immediately to the left of a sort of lodge (converted hut). The path climbs along the western flank of Gorramendi-Gorramakil and arrives gently onto a small plateau where there are two huts: Urtsuko Borda, sheltered by large rocks.
(1) Continue along the path, which veers sharply to the right. This path winds through the forest, crossed by a few streams. You will reach a clearing, Unizko lepoa (754 m), below the Uniz hill (778 m).
(2) The path heads back into the undergrowth to reach the Burdimotzeko Pass (898 m). You are now below Barda or Akomendi (956 m).
(3) Follow the path north-east towards Irubela, passing along the western flank of its ridge. A little further on, you reach the Gorostiko Pass.
(4) Follow the grassy path which veers south-east. Pass beneath and go round the 861 m peak on the right. Reach a pass (835 m), then continue along the path to the summit of Irubelakaskoa or Alkaxuri (950 m) by following the ridge line. This path passes through a rocky area but remains clearly visible. Magnificent views of all the peaks.
(5) Retrace your steps back to the Burdimotzeko Pass.
(3) Take a path on the left that climbs south-south-west along the ridge to the summit of Gorramakil (1090 m).
(6) Follow the track due south. At the first bend, leave it and take a path straight ahead which joins it a little further on at Col Otarnarteko (1032 m).
(7) Here, either continue along the grassy path which leads to Gorramendi or, as shown on the map, follow the track to reach the Gorramendi junction.
(8) Descend, still on this track, to the next junction.
(9) Turn right and follow this road back to the car park, past the Col Itzulegi (S/E).
