By car: Depart from Sare, take the D406 road to Vera de Bidassoa, via the Col de Lizuniaga.
At the pass, there's a hotel-restaurant. Park in the car park, leaving the spaces closest to the building free for customers.
On foot :
(S/E) Start out on the path that rises to the North, towards La Rhune.
After a bend to the left, at the "Larun" sign (la Rhune), reach a crossroads.
Follow the signs to the right. Pass the pigeon shoots and notice the boundary marker 35.
On the flat, more dovecotes and boundary marker 34. Follow this ridge path to the right, which climbs up and down past more dovecotes.
(2) In a hollow, pass boundary stone 32 and reach the long-closed Venta Negra (aptly named).
Bypass it on the right, climbing up a path (more dovecotes), first winding through the rocky outcrops, then making a very wide left turn as it becomes grassy. Reach a grassy plateau at the foot of the Urkillu ridge.
(3) Pass boundary marker 29 and head straight up the track, which curves sharply upwards towards a fault. Do not descend to the enclosure on the right. Walk along the scree and take the path that climbs through the rock to the top of the gully.
The view of the coast from the collet is magnificent. On the left, you can make out the red-and-white antenna of the summit of La Rhune, which you need to reach.
(4) Pass boundary marker 26 and reach the track leading to the summit, its ventas and the arrival point of the cogwheel railway on the north side.
(5) For the return journey, take the carriage track back to milestone 26.
(4) Leave the outward path on your left, and continue down this track, which makes a sharp right-hand bend.
(6) Below the summit buildings, take a small path to the left (broken sign illegible in 2017), which descends through grassy then stony passages.
The path widens as it passes over a sheep pen with an electricity pylon, then enters a larch forest.
(7) In a right-hand bend, turn left onto a path which descends and soon becomes a track again. Continue downhill on this track. Reach Venta Negra.
(2) Stay on the track which continues to the right, soon skirting a pretty stream, passing by a sheep pen and then climbing again. At the first farmhouse, turn left to reach the first crossroads.
(1) Return to the right and retun to the car park (S/E).
