Nowadays,
Zegama Apeadero is well known for providing access to one hard northern trail mounting up rather straight to a central pass by Andreaitz. The initial mud track going up west (PR-GI 70) peters out into a narrow trail at a major crossroads (col of Intzuzaeta) after taking a turn south-west. Signals are abandoned and the trail penetrates straight into an open
beech forest, where traces of the trail can go almost unnoticed. At the final stage of the ascension, the path winds up. At this point, autochthonous forest and steep slopes are left behind, yielding to a distinctive
karst and grazing landscape. Yet the main ascension route comes from the south-west, from the
Sanctuary of Arantzazu (Oñati), where a beaten trail goes up through a thick forest of
beeches and ends at the Urbia meadows. From there, the route climbs up to the summits (Aizkorri, Aketegi, Aitxuri and others). Way-marking will be easily found. Another access point lies on the east at the
San Adrian tunnel and the Medieval road crossing it. At the southern exit of the tunnel, after a 50-metre walk, from a clearing a trail penetrates almost unnoticed up the forest on the right, so beginning a 30-odd minute uphill struggle (not in vain is it dubbed
Kalbario Bidea, 'Calvary Trail') with loose pebbles all along. At this point, an opening affords a view onto the north and the trail cuts along the verge of several
limestone cliffs on its way north-west. In another 30 minutes, the
Aizkorri summit may be attained. A stark refuge hut (built 1934 as a shelter for shepherds and hikers) and the
Santo Cristo hermitage lie by the summit. ==Events==
