To reach the start, head to Itxassou via the D918. Follow signs for “Pas de Roland” via the D249 then the D349.
Once at Pas de Roland, take the road that goes straight on and follows the course of the Laxia. At the junction, take the road on the left that climbs to the Col de Mehatze.
(S/E) Descend along the track heading south-east and follow the boundary markers to the Col d’Artzatey. Continue along the path in the same direction, leaving the track that passes via the Col d’Espalza on your right. You will then reach the Zelhaiburu sheepfold.
(1) Continue on to reach the Zerkanbide ridge. Climb slightly along the ridge, then follow it along.
Above a stone-walled enclosure, head down until you reach a copse of trees.
(2) Follow the track to the left along the fence. Turn right to reach the Maraputxunea sheepfold. Cross the meadow to the gate, then cross the bridge over the stream. Follow the wide path back up to the road and head to the Olhatea car park.
(3) Follow the road due north, passing a lodge. Leave the road at a right-hand bend and follow the wide path which climbs northwards for about 800m, to the Eihera sheepfold.
(4) Take the path heading north-west, keeping to it and ignoring all the branches to the right or left, to reach the Col de l’Âne.
(5) Cross the Col de l’Âne plateau and take the path climbing south-west up the side of Artzamendi. Climb up to a large solitary oak on the slope near the ruins of Arimaluxenekoborda.
Continue along this path, first south-west, then south-east, following the yellow markings which lead to the summit of Artzamendi.
(6) Descend the grassy slope towards the south for about a hundred metres. Turn south-west to cross the access road to the air base and reach the Menditipiko Bizkarra ridge. Enjoy the view of Mondarrain and La Rhune from here.
Descend along the ridge via a path that is sometimes steep, to the Col de Mehatse (S/E).
