The Camino del Interior, the inland Camino de Santiago, is a path to Santiago that goes through Zegama and while less known by most people, offers the pilgrim the calm and peace of mind that define the true Saint Jacques Way.
Starting from Zegama, you can find several options to make it to San Adrián’s tunnel:
- One of the routes takes a trail to Iruetxeta’s hermitage, where you’ll start the track that goes around Sierra de Aizkorri starts, with an amazing set of pruned beech trees. Enjoy the woods! Then, reach the hermitage of Sancti Spiritu: previously a hospital and a resting place for pilgrims, travellers and shepherds. From here you will see the medieval causeway that takes you to San Adrián’s tunnel. This is a unique place for pilgrims, loaded with symbolism. In the middle ages it was a fortress and also a lodge to stop during the journey, get some food, or give your horses a rest. There was always a place for pilgrims in this tunnel.
- The other route will take you to the tunnel through what is thought to be the oldest path leading to San Adrián. The town of Zegama restored this path on the other side of the river Oria to San Pedro’s hermitage. From here, it goes up in the mountain and joins the other path.
