Park in the cul-de-sac that leads to a small bar-restaurant.
(S/E) Retrace your steps a few metres to a crossroads and turn right, crossing a cattle grid (Xarako bidea). Walk along the Lapitxuli River and follow it until you reach an iron footbridge.
(1) Cross the river and take the path that climbs to the right. After about 100 metres, take a small path on the left that also climbs, marked with yellow signs.
Pass in front of a shed, come out onto a road and go up to the right. Shortly before reaching the Arotzenborda farms, you will come to another crossroads.
(2) Take the path uphill on the left. Follow the yellow markings. At the top of the hill, at a three-way junction, keep right and you will come to a track.
(3) Cross and continue straight ahead to climb the Haizagerri ridge. Continue alternating between ascents and descents to reach the summit of Gorospil.
(4) Descend on the other side to the Gorospil Pass, then climb straight up to reach the ridge of Mount Bizkailuze. Follow it to the left. You will arrive at a large crossroads at the Zuharretako Lepoa Pass.
(5) Continue straight ahead on a well-marked trail along the same ridge to the peak of Mundarrain.
(6) Continue along the same path for a few metres, then turn right to descend off-trail, but within sight, and join the GR®10 at the Mendiko Borda barn-shelter.
(7) Take it to the right and arrive at the Gainekoborda crossroads.
(8) Continue along the GR® trail, then quickly leave it on the right to take the path and reach Pic Soporro. Descend opposite to the Col des Trois Croix.
(9) Cross the GR® here and descend the yellow-marked path. Pass below a pidgeon hunting hut. At the Erramuntenborda farm, join a wide track.
(10) Continue along the track, passing Peruertegikoborda farm. Stay on this track until you reach its end at the Perlaenborda crossroads.
(11) Turn right onto a path after the shed and before the farm. Overlook the Dantxaria quarries. Ignore the path on the right that leads down to them. Climb up and then descend quite steeply to the right into the forest. Reach a flat area and take the old pidgeon hunting hut path opposite (there is an old wooden ladder on the left), then descend to the Venta Pantxo car park (S/E).
