A salt-laden wind meets the prow of the coach as travelers leave Biarritz, crossing the border into the green headlands of Biscay. The first glimpse of San Juan de Gaztelugatxe is abrupt: a stone causeway, a jagged islet, and a ribbon of 241 steps that climb to a small hermitage clinging to the rock. The sea below dares you to linger while the Atlantic keeps moving.
