We say farewell to the Virgin of Arantzazu and follow the red and white signs that lead out of it. The Sanctuary remains on our right and we take the road away from it, leading up to the last houses. After the last house, at the fork we take left. We continue upwards, straight ahead. We arrive at a junction of three roads, with a fountain nearby. We take the middle road (with a signal indicating the way to Urbia). Later, after a few minutes of wide and shaded track, we find the spring at Erroiti, on our left, which marks the place where legend has it that the Virgin of Arantzazu appeared to the shepherd Rodrigo de Baltzategi.
The road zigzags as we make our way up to the mountain pass of Elorrola, following the red and white signs of the main road. We arrive at the mountain pass and start the descent. We arrive at the Chapel of Andra Mari de Urbia (1924), which we leave on our left to follow the dirt road and reach the shelter of Urbia, where in summer we can find refreshments at the Bar of the shelter.
We follow the dirt road, clearly marked and wide. Further on we pass between some shepherd huts in the meadows. A little later, we pass near the Zorrotzari monolith and the Perusaroi mountain shelter nearby. We go forward on the dirt road that descends steeply and then goes up once more. After a fence we should leave the track by a gravel path that leads through the woods (a very clear path) that brings us back to the track later on. Near where the path begins there is a blue pole with a red box on top, the Mail Box of Askiola.
By the time the wide track begins a sharp descent we have to quit it. There is another track on the left marked with red and white GR-282 that leads us to meet the Camino de Santiago which we can recognize by the yellow arrow and the remains of an ancien paved road. We follow the road leading to Santiago at least a few hundred meters down. Until a sign that tells us Zumarraundi (or petrolerak) on the left.
We reach the small plain called Zumarraundi. On the right an asphalt road begins, that leads to Araia (about 2km there is an indication on the left: “Araia 4km GR-25″ that avoids the asphalt). Going down it, we reach a reservoir: be careful here, because at the next junction we turn left and leave the main road. We leave a big house, Gartzabal, to our right. Keeping to the paved road, we enter Araia, after going through a complex of swimming pools. Going ahead in the direction we have been taking, we arrive at the church and the town hall.
