Take the road to the Col d’Ibardin. When you reach the pass, head straight on towards Bera; after the first bend on the right, take the small road branching off to the left. It winds through the forest, then passes the Okalarre restaurant and continues on to the Zahar restaurant.
(S/E) At the far end of the car park, to the right of the bridge leading to the inn, take the path straight ahead along the Intzolako erreka stream. The path runs alongside the stream, changing banks several times until it reaches a Y-junction with a wider track that heads north-east.
(1) Turn left onto this track, which leads out of the forest for about 300 m, then take the hairpin bend to the right towards the south-east onto a track that climbs along the edge of the forest and heads north for about 400 m.
(2) Take a hairpin bend to the right. Ignore a hairpin bend to the left and carry on straight ahead, heading south then east to join the Haute Route Pyrénéenne.
(3) Take a hairpin bend to the left to climb to the summit of Aritzmendi.
(4) Descend back onto the HRP (Haute Route des Pyrénées) and continue along a wide, circular descent leading to Venta Yasola. Continue downhill to the Descarga Haundi pass.
(5) Turn left onto the track heading south-west for a hundred metres until you reach a junction. Take the path on the left; this is a variant of the HRP which leads back to Venta Zahar and the car park (S/E).
