Iturriotz (580 m, the spot is reached through a road up setting out at Andatzarrate -road GI-2631-) is a former country inn, where according to historic accounts Ignatius of Loyola stayed overnight on his journey home from Paris in April 1535.

The trail heading south-east, after a long slope is overcome, a couple of zigzags on pebbled soil lead to the top of the mountain.

The route (PR GI-78), shrouded in vegetation, is marked all along on rocks, signposts and trees, with a general direction west running along the mountain range (left).

A dust track winds up from the road (GI-2634) to the very pass of Zelatun, so pick-ups and other SUV vehicles may be found at this spot, sometimes belonging to hunters.

The massif has been inhabited for millennia, as attested in the grotto of Altxerri, where in 1962 wall paintings and rock carvings depicting bison, horses, reindeer, fish and other animals were unearthed.
