3 h 30 min
Acces to Aldaola-Ubier parking to leave your car.
During your walk, you will see:
1. San Adrián tunnel. A magical and historical place.
2. San Adrián’s hermitage. It’s actually inside the tunnel!
3. Medieval causeway. It used to connect Castilla to the coast during the Middle Ages. It is part of the Camino de Santiago.
4. Santo Cristo de Aizkorri’s shelter and hermitage. Only 10 metres from the top, you will find this shelter and the hermitage. Spend the night there, if you need. From here you can easily get to the top of Aizkorri.
5. Top of Aizkorri. Excellent views from the highest peak in Euskadi. Not in actual height (Aitxuri is the highest peak, 23 metres higher than Aizkorri) but in popularity.
6. Sancti Spiritu’s hermitage. Go down the road that faces Aizkorri. History gives its origin to the Templars, which isn’t odd odd if we consider the location. Being a low-profile hermitage nowadays, only visited by shepherds and some travellers, it does not look like it belonged to the Military Order.
You can follow the Alaveses path that in the beginning coincides with the same route we have climbed but goes to the right following some red paint marks to Zalduendo. We will continue the descent until we reach Gr-283, point called Linategieta, where we will turn left. We will have to follow the Gr-283 to get back to the middle age road that we have seen at the exit of the tunnel.
