On the A63, take exit 5 (Bayonne Sud) and follow the D932 towards Ustaritz and Cambo-les-Bains. After 15 km, follow the Cambo exit ramp, then continue right towards Espelette (D918). After the Espelette exit, at the junction with the D20, turn left to continue towards Ainhoa. Pass the Col de Pinodieta and reach Ainhoa (car park near the fronton).
(S/E) From the fronton square, go up the main street (D20) on the right towards the church. Pass the crossroads and continue to the bend at the end of the village.
(1) Leave the main street before the first bend, going straight down and then immediately left. Take the street on the right, then at the next junction go up to the right at the car park and stream until you reach a Y-junction.
(2) Go down to the left (dead end straight ahead). The road goes uphill. Pass the first house and continue to an intersection towards Arbonakoborda.
(3) At the crossroads, take the road on the left, then left again. Continue to the D20 (stop sign).
(4) Cross the main road carefully and continue straight ahead on the road that descends to the right until you reach a crossroads.
(5) At the bottom, at the bend, continue straight ahead along a track until you reach a footbridge and a ford. Cross the footbridge and continue along the track until you reach a path that climbs to the left.
(6) Follow this steep track until you reach a road, which you should climb to the left. Continue until you reach a fork after a cattle grid.
(7) Leave the road and turn left uphill onto a track, then a path. Further up, follow a straight fence on the left and continue in the same direction until you reach a small summit (elevation 389).
(8) Turn left onto the ridge, descend towards a meadow (with a sheepfold) and walk along it on the left and below, towards a gate. After the gate, take the track and follow it to the left until you reach a farm.
(9) Leave the entrance (two red wooden posts) to a farm (Erremuntenborda) on your right and continue straight ahead, heading north, until you reach a fork halfway up the slope between Erremuntenborda and the main ridge.
(10) Leave the main path and turn left onto a balcony path. At a small beech grove, the path passes just to the left of the large beech tree. Continue in this direction until you arrive slightly above three large white crosses on your left. Join them (red and whiteGR®10markings) and the Arantze chapel (Notre-Dame de l'Aubépine).
(11) To the right of the chapel, start descending on a stony track. Follow it, passing in front of the Arantzazu fountain (virgin on the rock, on your left). Join a small road and take it to the right until you reach the first junction.
(12) Turn left and, at the end, take the pedestrian street between the recycling bins and the Maison pour Tous community centre. Walk up the alleyway that leads to the main street (D20) to return to the church and the pelota court. Turn right towards the square (S/E).
