To reach the car park from Itxassou, take the D249 towards Espelette. Continue for about 2.5 km and turn left onto a small road towards Panparrina and Col Atharri. After about 3.2 km, you will see a small car park on your left before a hairpin bend.
(S/E) From the car park, continue for about 200 m along the tarmac road through the hairpin bend, then take the path on the right that passes by a house. Cross the cattle grid and climb southwards with the Pic du Mondarrain opposite you. At the first intersection, go straight ahead and stay on the main path. When you reach a small grassy plateau with a fairly steep slope opposite you, take the gentler path on the right towards the west until you reach an intersection.
(1) At the intersection, turn left to go around the Mondarrain on the eastern slope. Cross a wooded area, then an area with very large rocks blocking the slope. You will arrive between the Mondarrain on your right and the Pic d'Ourrezti on your left.
(2) Descend to your left, heading south towards Pic d'Ourrezti, keeping it on your left. After about 700m of almost flat ground, you will reach a fairly steep and stony slope, then the track becomes grassy and very wide, leading to a pass.
(3) At the Col de Zuharreteaco (Zuharreteako on the map), at the junction with theGR®®10, go straight ahead. There is a wooden post about 50cm high at the start, and a gently sloping trail continues southwards to the ridges of Mont Bizkayluze. Follow the trail along the entire length of the ridges.
(4) You will arrive at the R76 border marker. Descend a few metres after the border marker to reach a pass in Spain.
(5) Take the path on the left that runs alongside a fence to reach a junction with theGR®®10.
(6) Turn left north onto theGR®®10. Reach the halfway point on the Col de Zuharreteaco.
(3) At the pass, do not continue onthe GR®®10which descends, but take a Pottok trail (in the ferns in summer) located between the descendingGR®®10and the ascending path. This trail winds halfway up the slope (west side) of the Pic d'Ourrezti and then the Mondarrain.
You will reach an area where the trail is a little unclear, near a sheep pen on the left.
(7) Head slightly left towards a large rock with trees to find a wide grassy path that descends to the right. Keep going in this direction to find a small path that crosses two more or less active but easily passable streams.
(8) When you reach a path descending from the Pic du Mondarrain, turn left and descend towards a triangular pine forest for about 100 metres.
Turn right onto the path that climbs up the eastern slope of Mondarrain. After passing through a wooded area with damp ground, find a path on your left that leads to the first crossroads you came to at the start of the hike.
(1) At this intersection, turn left and follow the path you took on the way up to return to the car park (S/E)
