From Irun on the N-1 towards San Sebastian, exit at Oyartzun and head up towards Altzibar
on the GI-3631. From there, follow signs for "Artikutxa" and climb up to the end of the road
(13 km) and the "Eskas" or hunters' house car park.
(S/E) From the car park, head due South, following the road for about 300 m.
(1) Enter the forest on a left-hand path (signposted Artikutxa NA-124) which continues due South. Follow this path through the forest for about 1800 m, crossing a stream. The path then bends sharply to the South. Follow it for about 300 m.
(2) Turn left, due East, until you come to a path heading north. Let this path go left and continue East.
(3) A few dozen metres further on, fork left onto the path which gradually climbs North-Eastwards. Reach the edge of the forest.
(4) Continue due North to the crossroads at 650 m.
(5) Turn right towards Izu. Follow this path for approx. 700 m and join a track heading North up the ridge.
(6) Follow the path to the left (North-West) and leave the track running due North on our right. Climb the ridge line and descend to the Bidango Gana pass. Continue opposite (NW), and follow the path to the rocky summit of Burnaiztieta.
(7) Continue along the NW path to Galzarrieta (813 m), then reach the Bianditz summit (844 m).
(8) From the summit, continue due West along the ridge. The scenery is magnificent on a clear day, with the "Peñas de Aya" massif within easy reach. Follow this path (GR® 121) until you reach the GI-3631 road, cross it and descend due South for 70 m to a track.
(9) Turn left on this track, which heads East and reaches the entrance to an old iron and kaolin mine (Artikutxa mine).
(E) As the track climbs back up to the road, follow the path around the hairpin bend to the right, due South, to reach the car park (S/E).
