To get to the start from Espelette, leave the D918 for the D249 towards Itxassou. Leave the D249 towards the Kukulu farm, then take the first left towards the Saint-Pierre Félix restaurant; this road passes through the Col de Légarré (Legarreko lepoa in Basque). Continue for two hairpin bends to find the car park located before the road that branches off to the left towards a pelota court.
(S/E) Continue along the winding road to the right for two hundred metres.
Turn right onto the path that climbs for 300 metres towards the south-west in the direction of Mondarrain.
(1) Continue on the widest path on the right, ignoring the ridge path that you will find further on.
(2) Turn right onto the ridge path that climbs to the foot of the summit.
(3) Turn left, heading south, to climb to the summit through the woods.
(4) Cross the summit of Pic du Mondarrain and descend via a circular loop to the right that goes around the woods you crossed on the way up and retrace your steps.
(3) Return to the fork in the path from the outward journey.
(2) Continue straight ahead to descend to the car park (S/E).
