From the village of Ascain, take the D4 towards the Col de Saint Ignace (the station for the little train to La Rhune)
Before reaching the pass, take the road on the left, passing over a cattle grid.
Follow this small road down to the car park at the bottom, next to the Terminen Muga sheepfold.
(S/E) Head south and walk back up several dozen metres. Then take the path that climbs up to the left, following the Arraioko Erreka stream. Walk up the valley until you reach a T-junction.
(1) Then turn left. After about 100 metres, at a crossroads, take the path that branches off to the left into the forest.
(2) At the next intersection, turn right at an acute angle. At the next fork, turn left. Go around the Zuhalmendi hill on the left and stay on the hillside. At a fork (elevation 222), take the path on the right.
(3) At the T-junction, follow the track on the left which descends to the corner of the Basque pigsty. At a fork, follow the left-hand track and you will soon come to a cross.
(4) Continue straight ahead, heading north-west, until you reach a T-junction.
(5) Turn left, then immediately left again, downhill. At the T-junction, turn left again. After a hairpin bend to the right, take the path downhill (not shown on the map) that heads straight towards a stream. Ford the stream.
(6) At the T-junction that immediately follows, turn left. At a fork, go left and, at the fork that immediately follows, go right (do not cross the stream). Continue along the path to the sheepfold (S/E).
