A salt wind cuts across the narrow causeway as travelers climb the zigzag stair to the hermitage at San Juan de Gaztelugatxe. Waves push against the basalt cliffs below, and the 231-step staircase becomes a rhythm — two steps, breath, two steps — that rewards with a stretcher of Atlantic panorama when the hermitage appears.
