The most easiest route to climb the peak Lakora is across the south face but I think what the routes across some of the ridges, east or west, are better itinerarys to climb. The circular route it's possible using for the descent the south face or the east ridge.
Valley of Belagua, Navarra (Spanish route)
Trailhead: Venta de Juan Pito (1150m).
Time: 2h30min (total 4h)
Location: road NA137 Isaba-Arette, to col of Piedra de San Martin (frontier France-Spain) 1 km before the refuge of Belagua
We begin to col of Arrakogoiti in Venta Juan Pito, the same route of peak Kartxela from this point. See the page of this route to approach to Col of Arrakogoiti.
In col of Arrakogoiti we turn to right (west) across the easy ramps of two little pre-summits of 1502m. After a little descent to a col (Portillo de Larregorri) we reach the bottom of the peak Larragoiti. In summertime it's possible the climb direct of west face with some steps of I but with snow it's not the better option. With snow we turn to left near of the metallic fence following a path over the rocks. This 20 meters had a exposed fall in north face to left side and the use of winter material it's necessary (crampons, ice-axe) to evitate the fall.
After this horizontal traverse of a few of meters we reach the wide ramp north of the peak and little by little we walk to the summit of Larragoiti (1683m). We descent to a col (cornises in winter) and we walk the great ramp of peak Cortaplana. The long ramp it's very wide and easy to walk to reach the rocky summit of Cortaplana (1781m) with spectacullar landscape with the summits of Lakora and the peaks of valley of Belagua.
The descent from the summit it's very pronunciated (not advisable in winter) and we reach a little col between both peaks. The last 90 meters of slope are the hardest of the route and with snow not are advisables because the great fall of north face (left side). The path go directly to the rocky Lakora West (1847m) with the vertex. In north direction we reach the main summit of Lakora (1877m).
