Park at the Paso de Otxondo.
(S/E) Cross the cattle grid to Gorramendi. Continue on this road NA-2655 to the next junction.
(1) Turn left and immediately right on the stony, uphill road to reach a grassy plateau where several tracks intersect.
(2) Take the path furthest to the right, which follows the NA-2655 overhang. Continue on this path, ignoring a path to the right and another to the left, for about 1km to reach the "T" intersection.
(3) At this intersection, turn left onto the wide track (part of the Route Napoléonienne), which leads up to a sheep pen. Continue along this track, ignoring a path on the right which descends along an area of pine trees. Reach a new intersection.
(4) Here, the path on the right is a dead-end, leading only to the summit of Mont Antsestegi. Continue on the wide path which starts to descend, and whose surface is concrete, becoming dirt a little further on. Continue to the next junction of 4 paths.
(5) Take the grassy path opposite, which bends slightly to the left. Continue on this path, straight ahead at the next 2 intersections with a path coming from the right.
(6) Take the right-hand path which runs along the edge of a row of beech trees and downhill. Continue on this path, then turn right and, a little further on, turn left to avoid the courtyard (with dogs) of the Larraldea dwelling, then turn left again, heading South. Further on, cross the cattle grid (with a low wall on either side) and continue straight ahead.
(7) After the second cattle grid, continue South on this wide carriage road. Reach an intersection after a hairpin bend that no longer exists on the ground, probably a logging road that hasn't been used for several years.
(8) Go straight ahead, the next track on the right leads to a house, so go straight ahead. A second path on the right leads to the top of the hill, so stay on this wide path. There's a third grassy path on your right, so continue straight ahead on this wide track, which leads back to the first crossroads you passed at the start.
(1) Turn right and head back down towards Paso de Otxondo, back to the start / car park (S/E).
